China S350GD G550 dx51d dx52d z150 z140 steel building galvanized steel coils sheets DX51D Slit Coil Manufacturer and Supplier | Ruiyi
Galvanized Steel Coils are produced through a process of metal coating which involves passing cold rolled coils through a kettle containing molten zinc. This process ensures adhesion of Zinc to the surface of the steel sheet. The Zinc Layer provides excellent corrosion resistance and prolong service life. Hot dip galvanized products are widely used in household appliances, transport, container manufacturing, roofing, base material for pre-painting, ducting and other construction related applications
