PRODUCT CENTER
Galvanized coil G550 belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc.
Q235 galvanized coil is a surface galvanized coil with yield strength of 235MPa. Galvanized coil, a thin steel sheet that is dipped into a molten zinc bath to adhere a layer of zinc to its surface. It is mainly produced by the continuous galvanizing process, in which rolls of steel sheet are continuously dipped into a bath of molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This steel sheet is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to about 500°C to produce an alloyed coating of zinc and iron. This type of galvanized coil has good paint adhesion and weldability.

SPCC is a commercial quality cold rolled steel sheet/plate as per JIS G 3141 standard. It is generally used for parts requiring bending, pressing, or moderate forming, and is commonly applied in automotive bodies, appliances, cabinets, and general metal products. It does not have inherent good atmospheric corrosion resistance and typically requires surface protection (e.g., painting, plating) for exterior use.
SA516Gr. 70 is widely used in petroleum, chemical industry, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, water turbine shells and other equipment and components.

The 4130 steel plate is a chromium-molybdenum alloy steel, typically supplied and used in the quenched and tempered condition. When the carbon content is at the lower end of its range, it can also be used as a carburizing steel for applications requiring a hard, wear-resistant surface and a tough core.
