DC01-06 Galvanized Steel Coil

Galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.

PRODUCT DESCRIPTION

Galvanized Steel Coil Uses

Galvanized steel coil has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.

Car board

The use of automotive plates must first be stamped and formed, and the steel plate is stamped into the required shape and size of the part.

Then spot welding, as an important welding method for thin plate connection, has a wide range of applications in the manufacturing industry, especially in the automotive industry.

Galvanized roof sheet

The performance requirements of galvanized roof panels mainly include the mechanical properties of the material (tensile strength, yield strength, elongation), coating performance (coating type, coating thickness and coating adhesion)

Home appliance office board

Including air conditioners, washing machines, refrigerators, photocopiers, etc., household galvanized sheets are mainly used for general forming applications and stamping.

Substrate

Another use of galvanized steel coils is to be used as the substrate of prepainted steel coils. prepainted steel coils have polyethylene coatings than galvanized coils and are more durable.
