Product Process

Hot dipped galvanized steel coil, the thin steel plate is immersed in the molten zinc tank, so that a thin steel plate with a layer of zinc is adhered to the surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel sheet is continuously immersed in a galvanized bath with molten zinc to make a galvanized steel sheet; alloyed galvanized steel sheet. This kind of steel plate is also manufactured by hot dipping method, but immediately after leaving the tank, it is heated to about 500°C to form an alloy film of zinc and iron. This galvanized coil has good paint adhesion and weldability.
