What is the device and its functions

The devices are installed not only on the window part of the building, but also on the doors.
Often, store or office owners use this function. They have the ability to put bars on windows and doors and lock them at night. Thus, the room will be protected at night. Different systems are installed for different types of premises. Often steel bars are installed on windows as decoration. To do this, they are made in various shapes. They are created to decorate buildings, apartments or houses. Such structures do not perform a protective function. You can simply take them off and get into the apartment. In order for the fence to have a beautiful appearance and protect the house, it is necessary to choose the appropriate systems.

Anti-burglary fittings

The most affordable alternative to gratings is replacing conventional trunnions with mushroom-shaped ones. The pin is the main element of window locking; they can be conventional or burglar-proof.

Photo: Roto NX V-shaped mushroom locking trunnion* The principle of operation of mushroom trunnions is that, when locked, they fit into reinforced strikers located on the window frame and cling to them with their “caps”. Due to the shape of the trunnions in the form of a mushroom cap, a reliable connection is achieved, and when the sash is moved with a hand tool, it is very difficult to open the window. The more pins, the smaller the distance between them and the more reliable the locking. In a standard sash window, 4-5 trunnions are installed, but their number can be increased to 6-7. The more there are, the higher the protection, and the larger the sash area, the more trunnions are required.

What to pay attention to

Knowing the capabilities of each type of grating, it is easier to make a specific choice. In this case, a number of nuances should be taken into account.

1. According to fire safety rules, it is prohibited to install blind bars on all windows on the first floor. At least one of them must have a sliding or swing structure.
2. The grate turns out durable and beautiful in appearance if an iron rod with a diameter of 16-20 mm is used.
3. When choosing a product, it is necessary to take into account the possibility of burglars entering the premises through the grid cells. Therefore, the distance between the rods in any direction should not be more than 15 cm.

Advantages and disadvantages

The advantage of bars is protection against attempts to break in, children or animals falling from the window.

You can install not just strong, but also beautiful products that will become an additional decoration of the room and harmoniously complement the interior.

Having studied different proposals, it is possible to find a design that is suitable in size, technical parameters, color, and cost.

Sliding products will not reduce the degree of fire safety, but removable ones suggest the possibility of moving to another window, for example, in case of moving.

Various images or designs can be applied to translucent polycarbonate grilles, for example, inside a nursery. You will be able to make a durable, beautiful design.

Dense polycarbonate supports the weight of an adult, which confirms its reliability.

The main disadvantage is the impossibility of exiting the building through the window in case of fire - the grille cannot be folded. Also, closed shutters will need to be opened, which will require a key.

The fastening must be as strong as possible so that the protection does not fall.

Another consequence of poor installation can be misalignment of the structure, which leads to the rollers getting stuck, making it difficult for the moving parts of the grille to move. When operating a skewed unit, the grille will stop opening.

Opening models and their installation cost more than their stationary counterparts.

Grilles are a universal design that can be installed on windows, doorways, and make partitions for zoning a room. They cover small departments with goods in shopping centers.

Purpose of the element

The main purpose of using window grilles is protection. The owners of the premises, of course, do not want this kind of design to spoil the appearance of the windows outside and inside the room, so they select a solution that can decorate the window openings. The market offers a wide range of goods and services of this kind and direction. The price is also different and depends on the material used and the complexity of the work, both in manufacturing and installation.

Window bars protect your home from illegal entry

Regardless of which design you choose and whatever design is made, you must remember that the main factor is its fastening. Such work can be carried out directly by the owner, or you can resort to the help of a professional craftsman.

Types of hinged grilles for window openings

"My home is my castle". Each of us strives to protect ourselves and our loved ones, to make our home a reliable fortress that protects us from intruders.

In addition to a reliable door, there is a need for protection of window openings. But how not to turn your home into a prison or a cage? Indeed, in the event of a fire, ordinary bars on window openings are an obstacle to salvation if the front door is blocked by fire. The risk of poisoning from combustion products is enormous.

In this case, bars on hinged windows will come to the rescue.

Types of gratings by manufacturing method

The standard design is a frame made of a 25x25 or 40x40 mm profile pipe, filled with a pattern of rods, squares, or strips. Preparation method:

• welding - with a pattern of simple geometric shapes. Steel reinforcement is assembled into a single structure by electric arc welding, constantly checking the accuracy of the connections, due to which the lattice acquires high strength. Weld seams are cleaned with an angle grinder and a wire brush. The metal is coated with primer-enamel, which creates an anti-vandal, anti-corrosion film on the surface. Production time - 2-4 days;

• forging - a pattern of various themes (floral ornaments, animal figures, monograms and logos). Despite its apparent lightness, the security grille is strong enough to detain an intruder and is resistant to external influences and weather conditions. Forging is divided into hot forging - heating the metal to give it the desired shape by hand, cold forging - deformation of metal blanks using mechanical action with forging equipment. The production time for forged products is from 3 to 7 days.

Materials used for gratings

Metal structures for house window openings are divided into two main groups:

• welded, which are inexpensive and can be afforded by different segments of the population;
• elite - forged, differ significantly in cost from the previous ones.

Types of grating designs
Welded gratings are made using steel rods that have a square or rod cross-section. You can also combine these materials. Welded gratings are used more as protective structures than decorative ones. Often a simple design is made, it consists of the intersection of rods, resulting in cells that have the correct shape. Such a lattice can be decorated with individual simple patterns; in this case, the metal is exposed to high temperature and, while it is hot, it is shaped. All resulting seams must be fixed by welding.

Forged gratings are more resistant to corrosion, but are much more expensive than welded ones

Forged gratings are made from hardened metal using cold or hot forging methods. The resulting structure is resistant to corrosion. Such grilles perform both a protective function and a decorative and aesthetic one.

Kinds

The grilles on opening windows differ in design. Manufacturers are trying to make them less noticeable so that a person does not feel discomfort in his own apartment. For this purpose, designs are developed using various materials. But it is worth remembering that fences primarily serve a security function.

Types of gratings:

• folding;
• swing;
• folding.

Hinged window grilles Folding window grilles Internal folding grilles

Folding

Among the different types, folding or sliding ones are the most popular. Their advantage is the ability to open the product during the day and close it at night. Thus, during the day, you can open the double-glazed window and not see the fence. At night it will protect you from intruders.

In small offices or shops, the mechanism will be an additional advantage. Then, the window opening also serves as an emergency exit. This is necessary according to fire safety regulations.

Such devices are easy to use. They are also installed on doors. This would be more suitable for a bank premises. It will be more difficult for a thief to get to the property. Usually, during this time, law enforcement agencies have time to arrive.

Swing

Swing mechanisms are those in which one of the ceilings opens. The products are suspended on hinges, so that parts can be opened. It complies with fire safety regulations.

The opening structure itself has no moving mechanisms. It is forged from steel rods. When you try to break in, the outer frame takes all the blows. Its durability is increased by pins located along the edges.

In order for such a metal structure to protect the premises, it must be installed in compliance with all standards. The standards include:

1. The rods are made of steel. Their diameter is at least 11 cm.
2. They are connected by welding or a forged-welded mechanism.
3. The individual elements are connected to the frame. It is made from a metal corner. The profile thickness is at least 5 cm.
4. The frame is fixed to the wall using steel pieces that go in to a depth of 10-12 cm.

Hinged bars on windows are often closed with a regular lock. This is the disadvantage of the product. The lock is easy to open, break the glass and get into the room. If the lock protects well, the weak link will be the fastening system.

Folding with internal arrangement

Folding types located inside have become very popular. Their advantage is the ability to open the metal structure during the day and close it at night. Thus, during the day, you can open the Euro-window and not see the fence. At night, the structure will protect against intruders.

Disadvantages of burglar-proof windows

You can open a regular plastic window in 30 seconds by quietly pressing the sash. The first and most important impact criminals have is on window fittings. If the window has 1 protection class, where only anti-burglary fittings are installed, the attacker will spend 2 minutes and will not be able to press the sash. Then he will move on to drilling out the handle, which in a normal window takes 30 seconds, but this cannot be done silently. With the 1st class of protection of the fittings, it will not be possible to drill out the handle, and after fiddling around for a couple more minutes, the “professional” will proceed to attempt to penetrate through the double-glazed window, which is accompanied by a loud sound.

Photo: a burglary-proof window will not allow a criminal to quickly and silently enter the premises. If the double-glazed window is protected, then after a couple of minutes the uninvited guest will understand that he has no chance and will disappear without achieving any results. Of course, with an hour of time and an arsenal of tools at your disposal, you can get into any house or apartment, but, as a rule, thieves expect 2-3 minutes.

Comparison of prices for bars and anti-burglary windows

No manufacturers or means of protection, including bars on windows, will provide a 100% guarantee against the entry of uninvited guests. They only delay the robbers, making their work inconvenient, more risky and longer. The buyer decides what level of protection to choose based on the budget allocated for the security of the property.

Methods for making window railings

1. Welded products. The cheapest option, which consists of steel reinforcement bars arranged in different orders. This can be a classic “checkered” lattice, a pattern of longitudinal or transverse rods, or the composition outside the window can take on other fancy shapes that the manufacturer’s imagination is capable of. This budget option can look whatever you want, the main thing is that it perfectly fulfills its main task and protects your home from the penetration of various types of ill-wishers.
2. Forged fences. This is still the same metal structure, but now supplemented with decorative designs and complex patterns. The most advantageous difference between forging and welded products is the external component - they are more aesthetically pleasing, lighter and more airy in appearance. Grilles with forged elements are an undoubted decoration of the facade and add elements of style to the entire house, while not forgetting to fulfill their main protective function. The option is no longer so cheap, since the production of products involves very extensive manual work. But an order for production will undoubtedly be worth the money if you involve a good designer in the design. Then you will certainly receive exclusive products that will emphasize and enhance the stylistic identity of the house.

Preparatory work

Preparing tools and materials for the manufacture of gratings is no less important than the production itself. After all, the quality of the finished product depends on correct measurements and accurate execution of the drawing. You need to start by taking measurements by preparing a tape measure.

Taking measurements

The success of the upcoming installation of the structure directly depends on the accuracy of the measurement. It is good if the outer part of the window opening is available for measurement. Depending on the chosen installation method, it is necessary to measure the height and width of the future installation location of the fasteners.

• external fastening . When taking measurements, be sure to mark the locations of future holes with chalk;
• internal fastening . Keep in mind that the grille, which is mounted in the slopes, must fit freely into the window opening. To achieve this, you need to subtract 10 mm from each indicator.

Drawing up a drawing

If you are not planning complex intricacies and intricate patterns in the window bars, then you can neglect the scale. A simple sketch with dimensions will be enough. Otherwise, the drawing of the window grille should be made in accordance with all the rules for its design. A squared notebook is perfect for this. It is important to note that the more accurate the drawing, the easier it is to subsequently calculate the amount of material.

Also, despite the artistic part of the work, one should not neglect the “physics” of the design. It must have stiffening ribs, which will ensure its strength. This function can be taken over by spacers. When the sketch has been double-checked and all dimensions are marked on it, you can begin selecting rolled metal. And if the size of the windows in all rooms is the same, then the amount of material can simply be multiplied by the number of windows in the building.

Tools, Supplies and Placement Types

There are several ways to install iron bars on windows, and each of them requires its own set of tools. Below is a general list, most of which you probably already have. Run your eyes over it and figure out what is already there and what you will have to look for.

So, to install bars on windows with your own hands you will need:

• a simple pencil;
• tape measure (5 meters);
• drill with drills;
• screwdriver;
• perforator;
• hammer;
• level;
• protective clothing and welding mask;
• electrodes;
• welding machine;
• angle grinder;
• self-tapping screws;
• anchor bolts;
• primer;
• paint for metal surfaces.

What exactly you will need from this will depend on the chosen method of placing the grille. Relative to the window opening, the structure can be installed in three different planes:

1. Outside.
2. Inside.
3. Between the glasses.

The most popular of them and the most classic is the external type. It is worth dwelling on it in more detail.

External fastening methods

You can secure a metal structure outside your window in the following ways:

1. Fastening by welding. The most reliable option. When working with a welding machine, it is very important to follow fire safety rules, use personal protective equipment, and also cover the window itself with sheets of any non-flammable material. It’s great if a friend comes to your aid who has not only the welding machine itself, but also experience working with it. Otherwise, you should play it safe and invite a knowledgeable and experienced person. The principle of fastening by welding is quite simple. First, we cut metal pins 12-15 cm long, depending on the size of the fence itself. Then, placing the grille against the window opening, we make 6 marks where the holes for these pins will be made. Next, in the places of the marks, we drill holes with a hammer drill, the depth of which is slightly greater than the embedded parts themselves. We drill holes of exactly the same diameter in the grille frame. After this, you need to lift the structure into the window opening and insert the pins into the drilled holes. The final chord is our welding. Using it, we secure the entire structure tightly.
2. Bolt fastening. With this method, you also cannot do without a welding machine, since the eyes need to be welded to the frame. Then, using a hammer drill, we drill holes in the wall of the diameter required for the passage of the anchor bolt. Next, we attach the grille to the wall and insert the bolts into the holes through the eyes. If you plan to get a removable structure, do not bore the splines and bolt heads. An important clarification: if the installation is carried out in a wooden house, then not anchor bolts are used, but self-tapping screws.
3. Wall mounting. This is the most unaesthetic method, since the bolts with which the grille is screwed to the wall will stick out into the room along with the nut screwed onto them. However, it is quite simple and energy-intensive and is popular when installing bars on the windows of technical rooms and warehouses.

Window bars today are becoming a necessary attribute not only for residents of the upper floors, but also for owners of private houses, offices and other premises that may, one way or another, become an object of interest for robbers and scammers. But metal grilles do not always make you feel as protected as possible. For example, when installing stationary grilles and a fire occurs, such grilles become not only protection, but also an obstacle. Therefore, the best option would be to install sliding metal grilles.

Design Features

Based on the method of movement, grating structures are divided into two types:

There is also a separate category - these are sliding metal grilles with upper and lower suspension. The movement of such gratings is carried out by rollers located in the upper or lower part of the frame. Grilles with bottom suspension are one of the most budget options. The roller can move along a guide, which can be U-shaped or T-shaped. However, this option has its drawbacks. For example, the load in such a design falls on the roller, so it quickly becomes unusable. To avoid its rapid wear, the guide and wheel should be lubricated regularly.

Sliding window grilles with top suspension move smoothly and softly. But a design with such a system must have the most durable guides, because it is on them that the entire weight of the grille will be supported. In turn, such guides significantly increase the cost of the entire structure.

Screen grilles do not have any guides. They simply fold into two parts, allowing the window to open completely. Among the advantages of the screen grille, it is worth noting the simplicity of the design, and among the disadvantages - height restrictions.

The opening method of louvers resembles standard shutters. The canvases of such grilles consist of lamellas that can move from vertical to horizontal space, thereby partially opening the window opening. Venetian blinds have a higher price compared to other designs. Such models can be made in the form of an accordion. Sliding grilles for accordion windows when folded occupy only about 20% of the window opening.

There are internal and external sliding grilles on doors and windows at the place of attachment. Internal grilles are installed directly in the room itself and open inward. One of the advantages of such grilles is the ability to quickly get out of the room in an emergency. In addition, grilles installed indoors are less exposed to the negative influence of the environment. But such designs also have a drawback: in the event of an attack on a room through a window, the latter will most likely suffer.

External grilles are installed on the facade of the building. They can be mounted inside the window opening, if space allows, or directly to the walls. Such grilles are considered the most reliable when attacking a room. But they require more careful care, because... come into contact with harmful external factors. In addition, if the rules of care in an emergency are not followed, they can become an obstacle.

Sliding grilles for balconies

Such structures meet all safety requirements and, in the event of a fire, will allow the structure to be quickly opened, without additional assistance from the Ministry of Emergency Situations team. A swinging grille on a balcony should not only provide protection from burglars, but also ensure complete safety for its owners in the event of an emergency.

Installation of gratings

If you decide to buy a sliding grill for windows, but don’t know which one is best to choose and how best to install it, then just call us. We will send our specialist to you who will help you solve the following problems:

1. Selecting a grille based on design, opening method and mounting location
2. Measuring and calculating lattice parameters

Already on site you will be able to find out the exact cost of your future grille and evaluate the appearance of the window with the installed structure.

In turn, the cost of gratings is influenced by the following parameters:

1. Dimensions
2. Material of manufacture
3. Lattice design features
4. Manufacturing features of the grating
5. Fastening and installation method
6. Additional services

Grill production begins only after all aspects and nuances of the product, timing and cost have been agreed upon. The on-site technician determines the complexity of the work, the fastening method and the need for additional work. We consider additional work only those services that do not relate to our products. So, if the walls around the window opening have crumbled or individual building materials are coming off, then before proceeding with installation, the craftsman will have to restore the integrity of the wall. This is necessary in order to create maximum reliability of the grid. After all, if you attach it to a destroyed wall, then, most likely, anyone will be able to pull it out along with the fasteners.

Selection of material

When making window grilles with your own hands from reinforcement, you should take into account the variety of sizes of this material. The most popular types of rentals for this are:

• square with a section of 10x10 and 12x12;
• round timber smooth or corrugated with a diameter of 10 and 12 mm;
• strips of metal of different widths with a thickness of 3-4 mm.

The following is often selected for the frame:

• corner 40x40 mm;
• the profile is square (25x25, 30x30) or rectangular (15x25, 20x30).

Depending on whether the grilles are intended to be opened, you need to take into account the hinges, locking mechanism (for hinged ones), rivets and wheels (for retractable structures).

Beauty or reliability

Most residents of ground floor apartments have to either put up with the presence of a steel lattice frame or install very expensive impact-resistant double-glazed windows. Often they try to give the gratings themselves a more elegant and aesthetic look, fortunately, modern technology can do a lot according to one’s desire. But it is worth remembering: the lattice structure on the windows of the first floor, assembled from elements of different lengths and shapes, can greatly lose strength. It will not be difficult for attackers to identify the weakest link at first glance.

Types of grating designs

Grilles used for installation on window openings of a house are of the following types:

• sliding,
• stationary;
• swing;
• double-glazed windows containing window grilles.

Stationary grilles are the most common type; they do not have elements that move, and during the manufacturing process they receive a solid protective sheet.

Stationary grilles are easier to manufacture and install than others

The hinged design can be opened as a whole leaf or as separate doors. The functionality of such gratings depends on the needs and imagination of the customer and the manufacturer.

The swing grille can be opened and closed

Interesting in the manufacture of grilles for window frames of a removable design, which are not mounted on the wall. They are installed directly into the window opening of the house using bolts and can be removed if necessary. This design is not particularly safe, but it is easier to install, and the façade of the building is not distorted by steel protrusions.

Removable grille is mounted in the window opening

Screens for sliding windows in a house are a fixed frame, have a system of sashes, they can be opened by moving them to the sides. They are not difficult to operate, are quite reliable and perform their main function. It should be noted that due to the peculiarities of its creation, this design has a lower rigidity than a swing lattice. Its doors fold like an accordion.

Sliding grilles have the following advantages:

• take up little space when assembled;
• there is free access to the window;
• fire safety requirements are met;
• aesthetic appearance;
• Due to the wide choice in colors, it is possible to purchase a design that suits your color.

Stationary grilles

They are installed only once and cannot be removed. If removal is required, you will have to carry out complete dismantling with sawing off with a grinder. Therefore, they raise questions from the fire inspectorate if they are located inside public buildings. However, it is a valid option for a country house or country house.

Steel products are sliding and removable. Sliding structures are fire-safe. The mechanism works like a blind or screen. Screen grilles are easier to manufacture, but even in the folded position the screen cannot be completely removed.

The grille-blinds rise up, does not interfere in the open position, and does not interfere with free visibility. The removable structure is secured with bolts that firmly fix the position; if necessary, the shutters can be removed.

Technical requirements for installation

The most important thing in fastening gratings is their operational reliability. For windows of standard sizes, it is recommended to install overhead grilles on a certain number of mounting bolts or pins. For the bottom and top of the window it is 1-2 elements, for the side ones - from 2-3 or more. Also, their number depends on the weight of the structure itself. Heavy welded and forged solutions can fall out of the wall along with a piece of it if the support is not strong enough or the number of pins is small.

For reference! Reliability of fastening is the key to the durability and safety of a protected home; moreover, ease of installation allows you to make truly durable structures.

Features of self-installation of the grille

If you have minimal skills in working with a welding machine and other specific tools, you can install a metal grill on your own, without the involvement of professional help. To do this you will need the following:

• drill and drill bit for working with metal;
• hammer;
• hammer drill with long drill;
• marker;
• welding machine.

For ease of work, it is better to do this with a partner who will support the grille during measurements or fastening.

Fastening the grille using bolts and eyes

How should you install bars on windows using bolts and eyes?
Drill holes in the walls with the same diameter as the anchor bolts. Then insert the structure into the opening and screw the pins through the eyes. The lugs themselves can be welded to the frame. After this, it is necessary to bore a slot on the bolt, that is, a special recess on the head. This will protect the grille from illegal removal. This method of fastening is suitable for installation in concrete, as well as wooden and brick walls. When attaching grilles to windows in wooden buildings, plumbing screws are used instead of bolts. This method allows installation both in the opening and in the overlay. Another nuance: fastening with lugs is suitable for forged gratings. In addition, if we are talking about wooden walls, you can attach iron grilles to them using threaded rods. In this case, holes are made through the entire wall. Then the grille is installed overlay and secured with bolts.

When installing gratings in a brick building, as a rule, the embedded pin method is used. The principle is the same as when attaching gratings to reinforced concrete walls. Holes are drilled between the bricks in the cement layer. Bolts are driven into them so that they protrude a few centimeters from the wall. The frame is welded to them.

When choosing a particular method, you need to take into account the characteristics of the building. So, sometimes windows are located flush with the wall, and in this case, installation only with an overlay is possible. At the same time, the strength of the walls must be taken into account. So, if the wall is wooden and there are doubts about its strength, it may not withstand a heavy forged lattice installed in an overhead manner.

Installing a grill inside a window opening

How to put a grill on a window inside a window opening? The process is similar to installing an overhead grille on a brick wall - it can be concrete, frame, or brick.

1. The locations for drilling holes are marked in the slopes. The marks are placed arbitrarily if the lugs are not welded to the grille.
2. Holes up to 12 cm deep are drilled (for concrete, Pobedit drills are needed).
3. Pins or anchor bolts are driven into the resulting holes, and the heels are welded to them.
4. The places where the lugs are attached are marked on the grid, after which they are welded to the structure.
5. The grille structure is welded to the embedded pins.

Installation options

The installation option for a metal product depends on many reasons. Firstly, it is important on which side of the opening the system will be installed. The mounting methods depend on the type of structure and the wall itself, namely, what material it is made of. In addition, the methods of attachment to the wall also differ. It is divided into the following types:

• welding fasteners;
• using bolts;
• end-to-end

Each individual type has both advantages and disadvantages. They are not universal for all devices. Therefore, the method of fastening often depends on the fence itself. Welding fasteners are the most reliable method. But after a while, the attachment point will begin to rust, and it is impossible to remove and replace it.

When using bolts, the device is removed. They will not leave marks on the walls. But such installation is not reliable enough.

The through-mounting of bars on the windows changes the appearance of the interior of the room. The fastening must be additionally masked. But this method is the only one possible for wooden houses.

Preparatory stage

Before you begin installing the product to the wall, you need to decide on the method. After this, the wall and glass unit are prepared. With some mounting options, glass may be damaged, so you need to take care of protecting it first.

Before starting work, prepare all tools and materials. Otherwise, you won’t be able to interrupt your work to get something. It's better if you have an assistant. He will help you carry tools or support the fence.

Welding

This method will be the most common. Often this applies to metal fixtures. First you need to take care of the safety of the window profile. It may be damaged during welding.

Concrete, cinder block and brick walls are suitable for installation in this way. Iron pins are driven into the wall and the frame and grille are connected by welding. The pins are driven in to a length of 12 cm. Another 3-4 cm are located outside.

Another way to attach the structure is to drill small holes in the fence frame and thus secure it to the wall.

Bolted

Products are fastened without welding. To install grilles on windows, you will need bolts. Depending on the material from which the wall is made, different types of bolts will be needed. Thus, anchor bolts are used for brick walls. For wooden ones, technical screws are more suitable.

The bolts are screwed in through special eyes. Holes are pre-prepared in the walls. At the very end, the screw heads are bored out.

Through

The method is to make a hole through the entire wall. The fence is secured with nuts that are threaded through the holes. In the interior of the room, the edges of the nuts are secured with bolts so that the system cannot be removed.

This method is suitable for wooden walls or vinyl siding.

How to paint a grille

Ready-made gratings sold in hardware stores are already painted. The need for painting arises if the grille structure was made on its own or the metal began to rust in some places. In this case, many homeowners are trying to find out how to remove the grill from a window for painting. This is only possible in two cases:

• overhead grille, installed with bolts;
• The design is hinged - it can be removed from the hinges.

In all other cases, you will have to remove the grate with a grinder. Therefore, you will have to suffer and paint the grill on the window. The process is simple and includes cleaning the iron from rust, applying a primer to prevent metal corrosion, and painting itself.

The paint should be powder - it is resistant to ultraviolet radiation, temperature changes, and perfectly protects the grille from corrosion. Costs from 360 rubles. for 1 kg. Warranty for about 20 years. An alternative could be alkyd enamel - the quality is almost as good as powder paint.

Types of window grilles

The popular opinion among ordinary people “there are no bars or locks against a thief” often turns out to be based on one’s own experience of overestimating the protective properties of roller shutters or roller shutters, internal removable bars, vandal-proof plastic windows, widely advertised by manufacturers of such products. Practice shows that we often perceive protection from an accidental blow or impact as a real system that protects against the intentional actions of a criminal. And these are two big differences.

The protective grill on the first floor window should:

• Warn and stop a potential intruder with your presence and appearance before attempting to penetrate;
• To be precisely a steel grille on the windows, made of high-quality material;
• Have secrets and tricks that the criminal is clearly not ready for.

Almost all government agencies have bars on the windows in their offices on the first floors, even if there are guards or alarms. This requirement is met for the first floors, although most people believe that even wrought iron bars on the windows are not capable of stopping an intruder equipped with modern steel cutting tools.

The bars on the ground floor are designed to detain the criminal for some time necessary for the main security forces to respond. But if, under certain conditions, there is no money or opportunity for additional measures, steel bars in the first floor windows will become the main protection against burglary.

Paint coating of grilles

In order for the grilles to serve for a long time, they need high-quality painting. There are many modern means for this. Some of them do not even require preliminary surface preparation and cleaning of rust. Although there are quite budget oil paints, their use will require additional application of a primer in color.

Products such as hammer paint for rust Hammerite and primer-enamel 3 in 1 have proven themselves to be excellent. Water-emulsion-based enamels are a cheaper option. Only for their greater reliability is it worth applying a transparent varnish on top. Of course, there are also aerosol cans, but their significant drawback is the excessive consumption of paint. In any case, the choice of color palette is huge; everyone can easily choose their favorite shade.

It is worth applying both enamel and paint with brushes of different widths for better painting. Hard-to-reach places should be blotted with a foam sponge. For example, such elements as fastenings and hinges of swing structures. It is more convenient to do this before installation. But if installation is carried out by welding, it is recommended to apply paint to the installed grille.

A few more nuances

The cost of production depends on the quantity and quality of the metal, the complexity of the design, its functionality and labor costs. It’s quite easy to make and install it with your own hands; the necessary materials and tools are sold at any hardware store.

Caring for the installed protection is also important - so that it does not collapse under the influence of natural forces and does not spoil the facade of the house with rusty streaks, it is necessary to choose materials that are initially undamaged by corrosion, carefully prime all elements, and cover the top with water-repellent paint.

For reference! Please note that covering all openings with blind structures is contrary to fire safety rules, because in the event of an emergency evacuation, exit through the windows will be impossible. In a convenient place for this case, place sliding or swing options.

Window decoration

Metal structures for windows come in a wide variety of shapes and varieties. The main criterion on which the choice of the appearance of the structure depends is the material from which it will be made. The following components are most often found in modern solutions:

• square;
• rod;
• stripes.

Rod and square are the most preferred because both materials are reliable and have high strength. It is through their use that the most diverse elements for decoration are obtained. For the manufacture of window grilles, a rod with a cross-section of 0.6-1.6 cm is used. For a square, this figure fluctuates within 1-2 cm. The strip, as a material, is much inferior to the others in terms of strength, and it cannot be used to achieve any special decorative effect. . But this is an excellent budget option for those who want to protect their home from theft, but do not yet have the funds to install an alarm system.

The use of one material or another determines the shape and design of the gratings. Flat structures are cheaper, most often made of a square or rod and are a two-dimensional product (located in 2 planes). Convex (or French) products look very elegant and unusual. In addition, they provide simple and convenient access to the window, making it easy to clean or paint. Convex grilles will cost an order of magnitude more than flat ones, and if you decide to get one, carefully study all the offers for reviews. Making such products requires skill and skill, so use the services of only trusted craftsmen and experienced designers.

In general, when you choose window bars, you need to pay attention to the following criteria:

• thickness of alloys and their strength;
• the quality of the fittings and materials from which they are made;
• professionalism of the craftsmen;
• price.

If you choose all the components wisely and think through the details, window grilles will not only provide you with protection from unwanted guests, but also an exclusive decoration of your home.

No. 4. Grating production technology

Most window grilles are made by welding, as it is cheaper. More openwork designs can be obtained by forging. Casting technology is used much less frequently.

Welded gratings

There is a popular belief that welded gratings are primitive structures with a very simple design. To prove this point of view, the example of a lattice in the form of a rising sun is usually given. These were very popular during the Soviet past, and they are still used today. However, welding technology allows you to create much more interesting designs that will not only protect, but also decorate the window.

The production technology of welded grating is quite simple. First, blanks of the required size and shape are made from a rod, strip or square. Everything is according to the previously drawn up sketch. The elements can be straight or in the shape of geometric shapes, but can be intricately bent. Interesting details are obtained using torsion, when a rod or square is twisted along its axis several times. When all the elements are ready, they are laid out on a non-flammable surface and welding begins. Welding areas are cleaned and smoothed, they can be hidden with special clamps - this is the ringing method. Sometimes small forged elements are welded to welded gratings. In general, the design is not as primitive and boring as many people think.

The design of the grille can be absolutely anything: the manufacturers’ catalogs are amazing in their variety, and besides, it is possible to make a grille to order. The design can consist of repeating elements, be symmetrical or abstract. Welded joints can be decorated with clamps, peaks, sheets and petals. Today, the lattice is no longer the primitive patterns that were used in the not so distant past, but you should not overdo it in this matter, so as not to greatly reduce light transmission.

Advantages of welded gratings:

• low price;
• speed and relative ease of manufacture;
• high strength.

The downside is that the appearance is less impressive than forged grilles, but manufacturers are working hard on this drawback, so it cannot be called critical.

Forged gratings

Forged grilles are made from square and rod, and the elaborate pieces resemble lace. Such gratings are more expensive than welded ones, since their manufacturing process is quite labor-intensive, and in terms of reliability, such structures are in no way inferior to welded analogues. They are perfect for the windows of a country house, and for an apartment in a multi-storey building it is better to use welded products.

According to production technology, forged gratings are:

• regular , in which clear symmetry can be traced. Made from rods with a diameter of 20 mm. Such gratings are cheaper than their analogues, they resist burglary quite well, but they look a little rougher than irregular gratings, and due to the thickness of the steel they take in too much light;
• irregular lattices are an example of openwork and airiness. Such gratings can be called a real work of art in metal. However, an irregular design is easier to break into, so the craftsman needs to accurately draw a sketch to obtain maximum burglary resistance. For these reasons, such gratings are more expensive than regular ones;
• mixed products consist of regular and irregular elements, and it is the areas where they meet that become weak points.

The main advantage of forged grilles is their high level of aesthetics and even artistry. This design will not spoil the window, but will even decorate it. The combination of a forged lattice and the same railings for the stairs will look harmonious. The only downside is the higher price.

Cast gratings

Structures of this type are inferior in terms of strength to welded and forged gratings. They are quite fragile and do not resist burglary well, but they are inexpensive, and artistic casting allows you to obtain quite interesting patterns. Cast grilles are rarely used; sometimes they are installed in offices where there is an alarm system, and the windows overlook the central busy streets.
