S280, S320, S350, S380 galvanized steel coils used for fences
Galvanized steel coil, also known as hot-dip galvanized steel coil, is produced by first subjecting cold-rolled or hot-rolled steel coils to pretreatment such as acid washing and cleaning, and then immersing them in molten zinc liquid to form a uniform zinc coating on the surface, thereby obtaining a composite steel material that combines the strength of steel with the corrosion resistance of the coating.
