ERW Welded Galvanized Steel Pipe 1-150mm Wall Thickness 6-2500mm OD with Grooved Ends
Zhengde galvanized steel pipes are available in both cold-galvanized and hot-dip galvanized variants, manufactured as round pipes or square/rectangular tubes. The hot-dip galvanizing process involves pickling to remove surface oxides, followed by cleaning and immersion in a molten zinc bath, resulting in uniform coating, strong adhesion, and extended service life.
