Metal bars on the windows (56 photos): choose beautiful and safe

If you live on the first floor in a block of flats or in a private house, then the problem of security concerns you much more than the inhabitants of higher floors. After all, attackers can penetrate into the residential premises of an apartment, cottage or office, not only through the door, but also through the windows. And as shown by criminal statistics, it is through the penetration through the windows and vents, which are located on the first floor, and the majority of burglaries are committed.

You can protect your home or office by installing metal welded or forged grilles on the windows, which, besides the protective one, also have a decorative function, sometimes being a real example of the art of forging. The article will look at how to choose the right metal grilles on the windows and what their types are.


What features are inherent in metal grilles designed to protect windows:

  • The metal lattice is a design from special shock-resistant steel with carbon impurity.
  • Each grille designed to protect windows has several basic elements of steel. These are corners, pipes, flat strips that reinforce the structure, and an iron bar as the basis of the whole structure.
  • The thickness of the rod - from 10 to 20 mm. Standard size is 12-16 mm. The rod is never hollow. It is always all-metal. Such a monolithic design enhances product reliability. Welded structures are always made from rods.
  • Carbon steel is not resistant to corrosion, so the grating is usually coated with powder coating or, less commonly, painted with enamel. Sometimes, especially in the manufacture of decorative structures, they use patina techniques and even gilding, bronzing and silvering.

Manufacturing techniques

How exactly are metal bars on the windows? There are two main methods - forging and welding. More details:



  • It is clear that in this case the rods are welded to each other.
  • With the help of this technique they make mainly protective grids using simple straight elements.
  • Inexpensive option, has a low decorative value, but reliable and durable.
  • Welded grates are often coated with enamel, as in an uncovered form, they make a depressing impression.


  • A much more decorative option, implies beautiful elements, elegant lines and aesthetics.
  • Have due to the complexity of the implementation of a higher price.

Types of lattices

Consider what options for metal gratings are available today and their features:


  • This is the so-called ordinary lattice of uniform cells - sometimes even a design that repels by its appearance. Primitive, but at the same time extremely reliable. Protective grilles are most often welded.
  • The main thing here is not external beauty, but reliability.
  • These types can vary with the thickness of the metal rod and the size of the cells. The smaller the cell, the more reliable the protection. But that and less light will fall into the room.
  • Residential apartments such a lattice few people make out. Most often they are intended for office buildings, banks, storages and archives.


  • The most beautiful and graceful of all kinds. They can be real works of art forging, have various decorative elements and details.
  • The cells here are of irregular shape, the whole lattice is a certain composition, and the cells are part of this composition, they obey it. The size of the cells can be quite large, if this is required by the drawing.
  • Despite the reduced level of protection functions, forged grilles cost more than welded ones. The fact is that it is much more difficult to create such a highly artistic work than a primitive horizontal-vertical mesh construction. This is a job for a real master, who has prices corresponding to his skills.

Protective decorative

Compromise option, combining good protective qualities and good decorative - is the most popular option, which is most often chosen by people for their windows.

Types of opening

On this basis, the lattices are of 3 types: sliding, folding and stationary. Consider them in more detail:


This option has a special device that allows you to move the grid, if necessary, folding it in half. The presence of such a function allows sometimes in sunny weather to open the windows wide open, and then re-install the grid. Features:

  • By the principle of work they resemble a screen. The most difficult in the engineering sense option.
  • It has a significant drawback - it does not prevent glass breaking and damage to the frame, it is not suitable for cottages or houses where they do not live permanently.
  • Closed with a lock.
  • Rarely decorative, as the folding structure does not allow for many interesting elements and techniques.


It also provides an opportunity to open the grilles, but only with the help of plowing - like a shutter. Features:

  • This option can be opened / closed both outwards and inwards. Here, every property owner is already watching how it will be more convenient for him. Usually open to the side of the street.
  • Happen with one or two shutters. For small windows, you can use a single-door construction, well, for large ones, of course, only a double-wing one.
  • The doors open quite easily. The child will cope with this, so this option is the safest in case of a fire. It allows you to easily leave the room.
  • Great for giving.
  • In order to secure the house, hinged windows are closed with special locks.
  • The cost of this option is higher than stationary. Fire safety regulations prescribe mandatory installation on one of the windows.


Another name - deaf or monolithic. Everything is clear here - this is the most common and simple form - they do not add up and are not removed. Once installed, they will "decorate" the window constantly. But this is also the most reliable option of all. Stationary welded or forged lattice is almost impossible to open, crack. More features:

  • They completely overlap the window openings, are very firmly fixed, are installed "for centuries". The ends of the metal pins are “bricked up” into the walls, the frames are welded firmly to them.
  • Such a structure cannot be removed or damaged without special tools and appropriate noise.
  • A significant disadvantage is fire safety - after all, through windows in case of fire it will be impossible to leave the premises.
  • They have the lowest cost, since it is easiest to manufacture and install these types of grids. You can also install it yourself with some skills and the right tools.
