ASTM A53 Hot Dipped Galvanized Steel Pipe - Round & Square Hollow Sections 10.2-165mm 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 oxides, followed by cleaning and immersion in molten zinc, resulting in uniform coating, strong adhesion, and extended service life.
