Galvanized coil is a thin steel plate that is immersed in a molten zinc bath to adhere a layer of zinc on its surface. The main production method is continuous galvanizing, which involves continuously immersing rolled steel plates in a molten zinc plating bath to produce galvanized steel plates;
Alloy galvanized steel plate. This type of steel plate is also manufactured using the hot dip method, but immediately after leaving the groove, it is heated to around 500 ° C to form an alloy coating of zinc and iron. This type of galvanized coil has good coating adhesion and weldability
