HOT DIP GALVANIZED STEEL PIPE

Hot dip galvanized steel pipe (also known as HDG steel pipe) is made by normal steel pipe coating with thick zinc layer. And this zinc layer protects the inner steel pipe from Oxidized and rusted. HDG steel pipe is always used for fluid (water) transport, scaffolding frame, structure pipe and decorative pipe.
