A safe (also called strongbox or coffer) is a secure lockable box used for securing valuable objects against theft or damage. A safe is usually a hollow cuboids or cylinder, with one face removable or hinged to form a door. The body and door may be cast from metal (such as steel) or formed out of plastic through blow molding. Safe history can be traced back to the Middle-Ages. In medieval paintings, occasionally to see wood cabinets full of gold and silver jeweler, this is the prototype of modern safe. Such safes shape of furniture, no special locks, lower security. Until 200 years ago, in the early 19th century, with the socio-economic growth, the safe industry began to develop, and there were special lock system manufacturers in Europe. 1818, the United Kingdom CHUBB company set up (in nearly 200 years later today, CHUBB safe has become a leading industry figures). 1825, France FICHE-BAUCHE company and many other companies set up, and then these companies were beginning to create safe. The material of safe from all kinds of solid wood into the metal, but the basic use the wood rabbet technique or the whole cast, no matter from the look or the process they all were similar to the furniture, and locks were not high degree of precision. In the late 19th century 50 the locks industry is not yet developed, although the safe appearance with each passing day at that time, but the locks were not great development in precision and reliability. 60 in the late 19th century, Americans invented the more lock bolt and lock bodies’ technology for the safes’ use, then the safe performance of the security have greatly enhance. In the 1960s and 1970s because of the ever-changing semiconductor technology, the industry developed electronic code lock. Electronic code lock was also widely used in various types of safe products. After again LED, LCD digital display used for the safe, on the other hand users’ demand hastened the birth of various types of fire safety products; Fingerprint scanning identify technology promote the development of fingerprint lock use in the safe; The popular of the magnetic card also derivative the magnetic card safe. Now, the safe products to the most simple function was developed to security, fire prevention, security / fire prevention, Magnetically-shielded, household, commercial and hotel use, firearms use, document / data, and other types. There are many categories of safe; Following is currently available in the market the more common classification of the safe. a) In accordance with its own anti-theft security of the safe levels can be divided into: safe, safe, collection boxes, safe deposit boxes, filing cabinets. b) The scope of use can be divided into: the hotel safe, business safe, home safe, guesthouses me, fire cabinet, filing cabinets, gun cabinet, safe vehicle, treasury door, ATM cabinets, counters, and other coin. c) By the panel and safe locks can be divided into the open the way: the electronic password series, fingerprints series, machinery password series, remote control campaigns, touch-screen series, IC card sensor series. Regardless of what model to buy the safe products, consumers should pay attention to the following areas: 1, the surface film (or spray film) color of safe should be uniform, can not have obvious cracks, gas gowns, dot defects. 2, the electronic anti-theft box should be targeted at least one electronic anti-theft locks, but not the use of magnetic locks. 3, when the box (and the door) composed by carbon steel plate production, the tensile strength of steel should be no less than 345 Mpas. The thickness of plate: A-level not less than 6 mm; B-level not less than 8 mm. When the box (and the door) structure by high-strength low-alloy steel production, the thickness of plate: A-level not less than 4 mm; B-level not less than 6mm. 4, safes’ door opening angle would not less than 90 degrees. The biggest gap between the doors with the door frames would not more than 2 mm. Both sides of the door surface would no larger than 2.5 mm. 5, electronic code lock can transform anyway, may be a number of password management and multi-level, three enter the wrong code, automatic locking or alarm. When by a safe, you can refer to this technical data to take a compare and ask the seller, further identify the quality of the products.
