AZ55 is the standard for galvanized steel sheets and coils used in a variety of applications, including roofing and siding. The AZ55 name refers to the thickness of the coating on the steel plate, which is between 0.375 and 1.5mm (0.015 and 0.059 inches).

Hot-dip galvanizing is one of the effective means to delay the environmental corrosion of iron and steel materials, it is the surface of the cleaned, activated iron and steel products immersed in molten zinc, through the reaction and diffusion between iron and zinc, in the iron and steel products surface plating good adhesion of zinc alloy coating.

Galvanized sheet 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 sheet is a surface galvanized sheet with yield strength of 235MPa.

Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel.
The following are some specifications that we often export, for reference only, if you have special requirements, we can customize, we will have professional designers to provide you with the most satisfactory style.

Galvanized sheet is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.

DX52D is a hot-dip galvanized pipe material. In order to improve the corrosion resistance of the steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer is thick, electric galvanized low cost, the surface is not very smooth.

DX51D galvanized sheet material is a non-ferrous alloy formed by adding other elements to the zinc matrix. The main alloy elements are aluminum, copper, magnesium and so on. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and resistance to atmospheric corrosion.

The Z275 galvanized steel sheet is a double-sided galvanized carbon steel sheet. This is produced by a metal coating process that passes cold rolled coils through a bath filled with molten zinc.

Galvalume steel sheet is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.
