ASTM A653 Rolled galvanized steel coil  

Galvanized steel coil, immerse the steel plate in the molten zinc bath and adhere a layer of zinc steel plate on the surface. It is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the molten galvanizing tank to make galvanized steel plate; Alloy galvanized steel sheet. The steel plate is also manufactured by hot dip method, but it is heated to about 500 ° C immediately after leaving the storage tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability. Galvanized steel coil has the advantages of strong surface oxidation resistance, which can improve the corrosion resistance and permeability of components, such as the back of indoor unit of air conditioner, the back of cabinet unit, internal components, and the shell and interior of outdoor machine are made of galvanized sheet. The working environment of these parts will encounter strong oxidation conditions such…
