The decision to install bars on windows implies an increase in the level of security of residential buildings. At the same time, the design and appearance of the grille must correspond to the existing architectural style of the building.
The variety of models and photos of window bars that manufacturers offer today allows the customer to objectively approach the choice of protective means of home protection. The customer can choose the necessary metal products in accordance with his wishes and financial capabilities.
One of the main requirements for protective security means is to ensure prompt opening of an object by Emergency Situations Ministry workers in an emergency situation.
Purpose of metal bars on windows
Metal structures of window grilles can perform a barrier function, providing protection for the object from external penetration and decorative at the same time.
Depending on their purpose, metal gratings are divided into:
Decorative. They can decorate a balcony or window opening on the lower floors of residential buildings. For the manufacture of gratings, class A 1 reinforcement with a diameter of 6-8 mm is used. When composing a pattern, the cell size is no more than 200 mm.
Security and decorative. The grid is made from reinforcement bars of class A 1 with a diameter of up to 14 mm. A simple ornament allows for cells up to 180 mm in size. This design significantly increases the protective function of the grille.
Security. If increased safety of the facility is needed, class A3 reinforcement bars with a diameter of up to 20 mm are used. The cell in this case should not exceed 150 mm.
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.
Choosing metal bars for windows
To protect metal-plastic or natural wood windows, many details should be taken into account when choosing grilles. It is worth understanding the manufacturing technology of the product.
It is also important to know the type of coating on the metal grille. The diameter of the reinforcement bars, the geometric dimensions of the grille and compliance with the window opening can be checked using a construction tape measure and calipers.
You should pay attention to how the ornament and pattern on the grille are made. It should not resemble a ladder.
Preference should be given to structures with welded rod joints. The cost of such products is relatively low with good security characteristics. The strength of the grating structure will be higher when using round and square profile rods.

Features of choosing the type of paint coating for metal grilles
In the process of producing such metal gratings and other metal structures, we use 3 main methods of painting them:
- 1) gratings painted using nitro enamel are distinguished by a smooth, glossy surface and mirror shine (the paint lasts about 3 years, after which the metal must be repainted);
- the Hammerite paint material will reliably protect steel from corrosion, the negative effects of ultraviolet radiation, and temperature changes (the service life of the coating is from 5 to 6 years);
- 3) the most practical and durable protective coating is powder coating , which retains its appearance for 20 years or more.
Cost of metal products
If you decide to buy bars, then the question will soon arise - where to buy bars for windows? Typically, specialized hardware stores sell all kinds of metal products to protect windows. However, we should not forget that there are private craftsmen who can adjust the price and please the buyer with a good discount.
It is worth paying attention to a company that takes measurements of windows for free before accepting an order. You should read reviews, compare prices, and talk to previous customers.
If there is a need to purchase inexpensive metal gratings, you can take unpainted products, as well as products made by welding the rods. In this case, the quality will strictly correspond to the price of the product.
The price range for metal grilles for windows is quite wide. The complexity of the design, the material used, and the popularity of the craftsmen also have a huge impact.
The approximate price of window bars varies from 1,500 to 4,000 rubles per square meter.
Useful tips
- Experienced craftsmen advise taking the proper time and drawing a sketch drawing to scale for subsequent accurate calculation of the material.
- In order not to miss the holes on the frame with the through fastening method, it is worth marking the edges of the pins with paint.
- You should not weld the frame element by element. First, the structure is assembled (by spot welding), and only then the grate is scalded.
- At least one grille in the building must have a swing design.
- It is very difficult to make an intricate forged lattice at home, so it is easier to purchase decorative elements ready-made.
- It makes no sense to buy a welding machine for the sake of making one or two gratings. It can be rented in specialized stores.
Making your own window grilles is much easier than it might seem. Especially if you have at least some skills in operating a welding machine, and you have a set of necessary tools at your disposal. It’s still worth starting with the simplest design. If you have a country house, first you can experiment with its windows. The main thing is not to neglect the preparatory work and observe safety precautions when working with welding.
