Galvanized steel is produced by passing cold rolled steel through a kettle containing molten zinc. This metal-coating process ensures the adhesion of zinc to the surface of the steel sheet, which provides excellent corrosion resistance through a process of sacrificial corrosion.Applications include roofing, base material for pre-painting, ducting and other construction-related uses.Available in plain or pre-painted sheets or coils.
