40-275g Zinc Coating Hot DIP Galvanized Steel Pipe - Round & Square Profiles 10-165mm OD
Zhengde Galvanized Steel Pipes are available in cold-galvanized and hot-dip galvanized variants, manufactured in both round and square/rectangular profiles. The hot-dip galvanizing process involves pickling to remove surface iron oxide, followed by cleaning with ammonium chloride or zinc chloride solutions, and immersion in a hot-dip coating tank. This method ensures uniform coating distribution, strong adhesion, and extended service life.
