To date, safe is a rather complicated technical structure, made of high quality and modern materials, metals, heat resistant and high strength concrete and composites. Safes basically have double walls, between which is placed a special filler.
Most of all, buying a safe, consumers choose between a fireproof safe and a burglary. First of all, you have to decide whether, from a risk you want to protect your valuables.
Burglar-proof safes are designed to protect valuables against burglary and unauthorized access to content. Fire safes, in turn, are mainly intended for protection against flames, heat, fire. Shells of both species are safe from the outer wall, the concrete layer and the inner wall. In the proof safes in concrete, which is located between the walls, added iron fittings, granite or marble crumb to increase the strength of the safe.
Fireproof Safes are between the metal layer of refractory concrete or aerated concrete. Today, more and more instead of concrete to reduce the weight of the steel safe to use composite materials. Burglar-proof safes are certain classes of burglary and fire safes - fire resistance classes.
Classes are 10 burglary, but the boxes that are on sale, have Burglar from first to sixth grade, and from the seventh - made to order. Safes grades 1 and 2 have a thickness of 5-10 mm of metal between which a solid concrete poured, the final wall thickness - 20-40 mm. Safes 3-4 class are somewhat different and more complex. Here the walls are made of steel with a thickness of 15-20 mm between the walls of poured reinforced concrete. Concrete reinforced with a 30-70 mm with two or three layers of reinforcement. This design can hold up to a skilled attacker 20-60 minutes - these are the results of certification tests in the life of the offender will take much longer. Castles in the vaults of a robust and expensive, often two. These safes are often installed in homes and offices.
It is very difficult technically safes are 5 and 6 classes. The walls in these safes - 80-200 mm. Manufacturers of these safes are not so much a testing time break is 10 hours. Accordingly, these boxes are expensive. Safes burglary of this class are often equipped with various safety innovations and non-standard devices.
In the manufacture of fire-resistant safes are used 0.5-0.9 mm thick steel. There are three classes of fire-resistant safes, which are denoted by letters: B, D, DIS. Class B is for storing important, and securities, and money. Fireproof safes are designed to keep the D magnetic media (film, magnetic disks, film, magnetic tape). Class Dis able to protect floppy disks. Near the lettering a fireproof safe is always digital (60, 120), which represents the time during which a fire contents of the safe will remain intact.
Fireproof Safes have a very low burglary qualities. Fireproof safes, above all, buy to store important papers and information carriers, and for the money and valuables to buy proof safes.
There ognevzlomostoykie safe, but if they have a normal rate burglary and fire, then there are very, very expensive. Ordinary safes this type of indicator is average.
Be very careful when choosing safe, because of your decision depends the safety of your valuables.
