Q
What is hot dipped galvanized steel pipe?
A
Hot-dip galvanizing (HDG), as referenced in 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 steel.
