What is hot dipped galvanized square&rectangular steel pipe?.
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel
into a kettle or vat of molten zinc. While the steel is in the kettle, the iron
metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that
provides superior corrosion protection to the stee
