To correctly decide on the steel door, you need to understand the indicators with which it should correspond. And first of all, this is ensuring the proper level of security. She takes responsibility for the safety of your housing, property, values and even the life of households! She must persistently prevent dangerous penetration, which can be carried out by means of selection of keys, by hacking or by a daring type of destruction. There are a whole list of rules and standards for the safety of the front door in the GOST instructions. In most cases, this list is reduced to four main degrees of stability.
The degree of resistance to autopsy is classified according to four criteria:
The first class – the door cannot be hacking, using only physical strength or using the simplest tools;
The second class – it is not opened when using heavy objects, such as a chisel, scrap, hammer, only by means of special electric equipment this is feasible;
Third grade – it cannot be opened even using electrical equipment;
Fourth grade – it provides complete protection against any type of weapon.
For steel doors to have at least the first class, they must have a frame structure made of steel pipe and have additional stiffener ribs. The sheathing of the canvas consists of two sheets of steel, the thickness of which is at least 2.5 mm. For reliable safety, two locks with different opening systems are mounted. The design itself should be made in such a way that access to the locks is as difficult as possible.
What standards should the steel door meet
If it should provide the highest level of protection, then the requirements for equipment become as high as possible. Auxiliary internal grilles are installed on the design. In addition, it is equipped with special materials with anti-abrasive characteristics. Manufacturers produce such designs of input steel canvases, with which when pouring concrete, the box forms a monolithic block with a wall. This design cannot be knocked out by any means. Its inner part can be empty, or to accommodate soundproofing and thermal insulation materials.
If you take care of the appearance of your elite housing, then look at the entrance doors with glass that can not only protect you from crackers, but also decoratively decorate your country mansion. Equipped with glass looks excellent, but also have high -quality technical characteristics. The window opening is completely sealed. The thickness of the double -glazed window provides excellent thermal insulation. A reliable original grate is installed on the glass.
Grace with glazing and decorative forged grille
Most manufacturers today have doors with forging and glazing elements. The consumer should not scare the fact that these structures do not have a continuous version of the door leaf. They are not inferior in terms of reliability due to the use of the strongest reinforced glass in their production. Moreover, such products belong to the elite class of models. They look like an expensive work of art. With their help, you can adorn even the most magnificent mansion with dignity. Such designs are mainly performed on order, on which highly qualified specialists work.
