G550 Galvanized coil

G550 galvanized coil is a surface galvanized sheet with yield strength of 235MPa. Galvanized 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 500degC to produce an alloyed coating of zinc and iron. This type of galvanized coil has good paint adhesion and weldability.
