Hot Dip Gal / Zero CF
Hot Dip Galvanized, Chromium-Free Coated Steel
Hot Dip Galvanized / Zero CF
Manufacturing Process
-
1
Surface Preparation (Surface Preparation)
Chemical wash or sandblast and acid treatment to prepare the surface
-
2
Hot-Dip Galvanizing (Hot-Dip Galvanizing)
Dip in molten zinc at ~450°C with controlled uniform coating quality
-
3
Cooling (Cooling)
Cool to allow the zinc layer to solidify and adhere
-
4
Chromium-Free Coating (Chromium-Free Coating)
Apply chromium-free coating to enhance corrosion resistance and reduce environmental impact
Properties
