Hot dip galvanizing is an industrial process where steel undergoes pickling to remove surface iron oxide, followed by cleaning in ammonium chloride or zinc chloride solutions, and finally immersion in a molten zinc bath. The resulting alloy layer bonds the zinc coating to the steel substrate, providing superior corrosion protection for applications in construction, appliances, automotive, and power industries.

Product Benefits
Hot dipped galvanized steel coil is manufactured by processing full hard sheet through acid washing, rolling, and zinc immersion. The resulting zinc coating provides exceptional corrosion resistance, paint adhesion, and workability due to zinc's self-sacrificing protective characteristics. This process enables precise control over zinc coating thickness (maximum 120g/m²) and surface finish options including zero spangle or extra smooth treatments.
