  • Hot-dip galvanizing (HDG) is a process for protecting steel from corrosion by completely cleaning the steel member and then immersing it in molten zinc. The molten zinc reacts with the steel surface to form stratified zinc-iron alloy layers which are metallurgically bonded to the steel. 

    A properly applied HDG coating is highly impact and abrasion resistant with alloy layers harder than the underlying steel and easily stands up to rough handling in the field.
