The most important task of the Eco -Rospon door in Moscow has always been ensuring the safety of not only an apartment, office, cottage or bank, but also any room at the entrance of which it is installed. Such a door should prevent the penetration into the protected room. The door made professionally should have sufficient resistance when selecting keys, hacking or destroying door nodes.
By acquiring a steel door, you should be convinced that you will not be robbed and it will serve you for a long time.
Doors, by stability to hacking, are divided into four classes:
– The first class can be attributed to doors, which cannot be opened to a specialist using only the simplest tools and physical strength;
– The second class includes doors, which cannot be opened to a specialist using any static tools (crowbar, chisel, hammer), except for electric;
– The third class includes doors, which cannot be opened to a specialist using various tools, including electric ones, the power of which is less than 500 watts;
– Grade 4 is assigned to the most reliable doors that provide bulletproofing (from small arms of any kind). Such doors are called armor -piercing.
No less important is the installation of the door in the opening. The door must be reliably mounted in the opening.
Each such door should have a certificate of compliance with a particular stability class.
