Product Description

Galvanized steel coil, immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin steel plate on the surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.

Cold Rolled Steel Reduction is the process of reducing thickness of hot roll pickled strip to lower target gauge points. Our factory use a reversing mill and a complex automation system to target precision gauge points. Our cold reduction mill services make steel harder and stronger. This process is called work hardening. Subsequent heat treatment is necessary if the application requires formability.
