Product Introduction

Hot-dip galvanized coil is a steel coil that has undergone a galvanization process, where it is immersed in a bath of molten zinc. This creates a coating that provides excellent corrosion resistance and enhances the steel’s strength. The zinc coating, typically between 3 to 20 microns, serves as a sacrificial anode, protecting the steel substrate from corrosion. With an estimated lifespan of 15 to 30 years in neutral environments, hot-dip galvanized coils are widely used in construction, automotive, home appliances, and agricultural facilities.
