Galvanized coil, dipping a sheet of steel into a molten zinc bath so that it adheres to a sheet of zinc on its surface. The main use of continuous galvanizing process production, that is, into a roll of steel plate continuous dip in the melting of zinc plating tank made of galvanized steel plate; Alloyed galvanized steel sheet.
The steel plate is made by hot dipping, but immediately after it is slotted, it is heated to about 500℃ to form an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weldability.
