Conscientious manufacturers, such as bastion-s, use only the highest quality materials, the latest equipment and time-tested technologies for the manufacture of metal doors. Thanks to this, modern steel entrance doors boast not only by increased gusts and strength, but also by a beautiful appearance.
Equally value is attached to the stiffness of the canvas, the thickness of which is usually at least four centimeters in basic models and at least five centimeters in anti -vandal structures. The vertical and horizontal rib frame of the steel door can significantly improve the rigidity of the canvas and increase its resistance to mechanical deformations. The canvas is sheathed on both sides, for which iron sheets of three -millimeter thickness are used.
The design of the entrance doors is such that it provides excellent protection not only from strong blows, but also from the penetration of attackers using various tools and devices. To enhance strength, the most important elements of the steel door, such as loops and locking mechanisms, can be reinforced with armored plates
It must be remembered that without high -quality and reliable locks, metal doors are only a useless piece of steel. Therefore, they must be equipped with at least two locks of different types. The leaf has a low level of secrecy, but it is perfectly confronted with knocking out. The cylinder, on the contrary, is less protected from gross power, but it is almost impossible to hack it with a master. Иногда они объединяются в один запорный механизм, но чаще всего устанавливаются по отдельности.
An important elemental of any iron door is the pins that are advanced when closing, also known as rigels. When the lock is in a completely closed position, the pins are automatically placed in special grooves. Even if you cut the loop at such a door, it will still be impossible to open it without a key. To protect the locks from drilled, and the loops from cutting, they are protected with thick durable armored plastins, which will not take a grinder or drill.
However, entrance metal doors are not only effective protection against thieves, but also protecting the dwelling from cold, noise and unpleasant odors. Smells and dust from the entrance are delayed with hermeted rubber seals located around the perimeter of the canvas, and the protection against cold and noise are insulating materials that fill the voids of the door box.
