Product Description
Product Overview
Zhengde galvanized steel pipes are available in both cold-galvanized and hot-dip galvanized variants, manufactured as round pipes or square/rectangular hollow sections. Hot-dip galvanizing 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.
Manufacturing Process
Square and rectangular hollow sections are produced from processed strip steel through uncoiling, flattening, coiling, welding into round tubes, and then rolling into square/rectangular shapes before cutting to required lengths.
