Product Description

Galvanized steel coil, a thin steel sheet that is dipped into a molten zinc bath to adhere a layer of zinc to its surface. It is mainly produced by the continuous galvanizing process, in which rolls of steel sheet are continuously dipped into a bath of molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This steel sheet is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to about 500°C to produce an alloyed coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
