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. Not recommended to buy steel Popular in the market, more safe materials used are steel, ordinary low-carbon steel and low-carbon alloy steel. 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 the characteristics of the industry, it can have both fire prevention and anti-theft functions. In 1990, it was developed by Chap, the largest safe manufacturing company in the UK.

An industrial pendant lamp is a type of lighting fixture that is designed to hang from the ceiling and provide focused illumination in a specific area. It typically features a metal or metal-inspired design, with exposed bulbs and a minimalist aesthetic. Industrial pendant lamps are often used in commercial and industrial settings, such as factories, warehouses, and workshops, but they have also become popular in residential spaces for their unique and stylish look. They can be used as task lighting above kitchen islands or dining tables, or as statement pieces in living rooms or bedrooms. Industrial pendant lamps come in a variety of shapes and sizes, and can be customized with different finishes and materials to suit different design preferences.
