In the modern world, apartment thefts are not so rare. Often, attackers fall into housing through the windows. Therefore, the installation of protective metal grilles on windows is a necessity, especially for windows that are on the first floors.
Protection of window openings has already been known for many years. Metal lattices are made forged or welded. Welded gratings have greater strength, but have simple patterns and drawings. They are widely used because of their low cost. Forged lattices look much more elegant and more solid, however, in order to make them, it is necessary to spend a lot of time and effort. Therefore, forged lattices are much more expensive than welded.
Of course, metal lattices, regardless of whether they or welded, reliably protect the window openings. But they also have certain shortcomings. For example, they are attached to the wall quite firmly, which does not allow them to open. And this means that you have to look through the window through a steel lattice, that not everyone likes. They fit very difficult to the general view of the building. In unforeseen circumstances, for example, a fire, it will be impossible to get out through the window opening.
