Hot Dip Galvanized Steel Pipe, Galvanized 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 steel.

Galvanized Steel Pipe Fittings & Galvanized Steel Flanges hdg hot dipped d welding steel

Hot Dipped Galvanized. Hot dip galvanizing (HDG) is a process in which steel flanges are submerged in molten zinc at a temperature of 850F. During this process, the molten zinc reacts with the steel to form thin layers of zinc alloys. These layers form a barrier that can provide exceptional corrosion protection compared to more traditional methods.

HOT DIP GALVANIZED - AK Steel

HOT DIP GALVANIZED STEEL, known as ZINCGRIP® Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.
