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
