Galvanized Coil

A galvanized coil is a thin steel sheet that undergoes a process where it is immersed in a molten zinc bath to create a layer of zinc on its surface. It is primarily produced through continuous galvanizing, a process in which the rolled steel plate is continuously submerged in the molten zinc bath to form a galvanized steel plate. There is also alloyed galvanized steel sheet, which is produced using the hot-dip method. After exiting the zinc bath, it is immediately heated to approximately 500°C to create an alloy coating consisting of zinc and iron. Galvanized coils exhibit good coating adhesion and weldability due to the zinc layer adhering well to the steel surface. The galvanization process provides corrosion resistance and protects the underlying steel from environmental factors.
