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.
What types of window grilles are there?
Window grilles are made according to the shape of the window: rectangular, round, rounded at the top, etc.
Depending on the design of the grating, there are the following types:
- Stationary. It is mounted directly into the walls and remains in the house for centuries. Reliable in cases of emergency exit.
- Sliding. It moves away conveniently, but due to the design it loses some of its rigidity and strength. If necessary, I open the window opening up to 80%.
- Swing. A grill that protects against entry from the outside, but in emergency situations (fire, etc.) allows you to escape through the window. One of the most popular options.
- Removable grid. Bolted on. On the one hand, it still makes it possible to get out of the window from inside the house, but in a state of panic, only a person with nerves of steel and pliers in his pants can unscrew all the bolts in a short time. If this is not you, then think about the feasibility of this option.
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.

Basic window grill design
A window grill always has a base: a corner frame made of a 15 by 15 cm profile pipe. Parallel rods, round or square, with a diameter of 10 mm, are welded onto it. The standard safe distance between parallel bars is 15 cm: you can neither crawl through them nor get stuck. Forged or welded decorative elements are superimposed on the base, forming the overall picture of the design.
The grille can be installed:
- Overlay - on the outside of the window opening.
- Into the opening itself.
- On anchor bolts.
- On pins without welding.
- On pins with welding.
The type of installation depends on the type of walls and the design of the gratings, and is installed by the surveyor on site.
