Surface Treatment Methods for Steel Material Boxes

The steel material boxes we produce need surface treatment. Generally we use powder coating on the surface, and for special requirements we also use cold galvanizing or hot-dip galvanizing. Some people ask whether the surface of a steel material box can be dip-coated (plastic dipping). Given the special nature of dip coating, as far as we know there are few steel material boxes in China whose surface treatment is dip coating.
