According to the national standard GB10409-2001 "Anti-theft safes," the material requirements for anti-theft safes are: The steel used in anti-theft safes should have a tensile strength of not less than 345 MPa.
The national public safety industry standard GA166-1997 "Anti-Theft Safe" requires the material requirements of the anti-theft safe box: the thickness of the steel plate should not be less than 6 mm when using ordinary low-carbon steel plate to make the box; when using low carbon alloy steel plate to make the box, The thickness of the steel plate should not be less than 4 mm.
From a durable point of view, the best material should be stainless steel, especially as a surface material, the more light it is. Its strength, corrosion resistance, color unchanged. However, there are many types of stainless steel, which can be mainly divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless iron, a long time, the environment is not good will rust, only austenitic stainless steel will not rust, the identification method is simple, use a magnet to test can be identified.
Copper is one of the most widely used lock materials. Its mechanical properties are good, corrosion resistance and processing performance are good, and bright color, especially copper forged handles and other lock decorative parts, the surface is flat, high density, no porosity, Blisters. Both strong and rust-proof, can be used to plate 24K gold or gold and other surface treatment, it looks magnificent, noble and generous, adding a lot of color to people's homes.
Steel + cement, commonly known as cement cabinet, is generally made of low-priced safe selection materials. It is made according to national standards for use with no less than 3MM steel plate + cement foaming cavity. Such safes are idiot due to the presence of cement, but they are also vulnerable to damage by the drill head and lose the anti-theft function. Due to fierce competition, there are unscrupulous merchants who use the iron plate clips that have been treated to cover the skin and wrap the cement. It is also a drill to wear, and the anti-theft capability is very low.
Steel is popular in the market, and the material used in more safes is steel, which is divided into common low-carbon steel plates and low-carbon alloy steel plates. Most of the safe deposit boxes are made of low-carbon steel plates, and the anti-theft performance is slightly weaker. The vast majority of safes with low-carbon steel plates have passed the national 3C compulsory certification. The thicker the steel plate, the deeper the box, the thickness should be more than 6mm, and the thicker the safe is the better.
The plastics used in plastic safes are not ordinary plastics. Instead, they are made of special materials with the addition of molten aluminum, ceramics and minerals. Due to industry requirements, it can have both fire and anti-theft functions.
