Hot-dip galvanizing (HDG) is the process of coating fabricated steel by immersing it in a bath of molten zinc. There are three fundamental steps in the hot-dip galvanizing process; surface preparation, galvanizing, and inspection. Hot-Dipped Galvanized Steel Coil | SHUNYE The hot-dipped galvanized steel coil is manufactured by using the cold rolled steel coil as the base plate and exploiting the continuous hot dip galvanizing. It is characterized by strong corrosion resistance, goof surface quality, facilitating deep processing, high practicability, high economy, strong ageing property, uniform coating, etc. 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.
