Your knowledge of metal doors
Metal entrance doors, in comparison with products made from other materials, have a number of obvious advantages. Metal doors are suitable for installation in residential, office or industrial premises.
Equipped with additional elements, which increase the protective function, the entrance metal doors are now in great demand. In the near future, the question of installing metal doors, caused the residents to be perplexed - what to do with the door, if the mortise lock went out of order or the keys were lost? But at the present time, replacement of door locks occurs quickly and inexpensively. There were many specialized companies to replace door locks not only in Moscow, but also in other settlements. If this question is removed from the agenda - the metal front door becomes an indispensable option.
What is the indicator of the quality of the metal entrance doors or how do you feel that this model is yours? Of course, these are the parameters:
• availability of a reliable door box
• a tamper-resistant locking mechanism
• availability of high-quality accessories (bronenakladki and loops).
Therefore, when choosing an entrance door, it is necessary to be guided by such a notion as the "class" of metal doors.
What does the term "class" of metal doors mean?
The term "class" of metal doors means the characteristic value. If we combine the common notions of noise insulation, fire resistance and door resistance to burglary, the concept of "class" will eventually be defined. However, it is necessary to shed light on the concept of burglarproof.
The class of burglary resistance is not fundamentally dependent on the class (reliability) of the castle. Therefore, the protection class of the metal door combines the following parameters:
• design features
• fabrication material
• method of fastening the lock
• Protection against mechanical impact and access.
The choice of the type of the entrance metal door should be based on the qualitative characteristics of these parameters.
But not always the external appeal of the door can become a criterion for choice, in this case it is better to give preference to the class of protection of entrance metal doors.
Classes of protection of metal doors
There are the following classes of protection of metal doors, according to the regulatory standards of regulatory documents:
Class 1 door must resist attempts at penetration using physical strength. In deciphering the notion of "physical strength", the door of class 1 does not need, because the manufacturer theoretically guarantees protection from karatist kick.
Class 2 door must resist the breaking that can be done using a primitive tool, namely a screwdriver and pliers.
Higher 3 protection class will not succumb to the attempt of breaking with the use of massive tools - notorious scrap and Fomka.
Class 4 Door will rebuff the attempt to penetrate using complex tools and their successful combination, namely a drill and a chisel, a hammer and an ax.
Class 5 Doorconceals behind itself in the bowels of the apartment untold treasures and wealth, because who will be at 2 o'clock in the morning to open the door with the use of powerful electric tools - grinders, abrasive and grinding tools.
And, finally, door of class 6 It should withstand the invasion of aliens with laser installations.
