For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This galvanized coil has good paint adhesion and weldability.

The passivation treatment of the galvanized layer can reduce the formation of rust (white rust) under damp temperature storage and transportation conditions. But the anti-corrosion performance of this chemical treatment is limited and hinders the adhesion of most coatings. This treatment is generally not used on zinc iron alloy coatings. In addition to surface finishing, as a routine, the production plant passivates other types of galvanized coatings.
