Hot Dipped Galvanized Sheet Metal

Hot dip galvanizing is a process of coating steel with a thin zinc layer which serves as a barrier between the steel and the environment.

Hot dipped galvanized sheet metal. The hot dip process pioneered by ak steel provides a tight metallurgical bond between the steel and the coating. Cold reduced sheet steel material in coil form hot rolled pickled is sometime used is uncoiled and passed continuously through the galvanizing line equipment. The finish is applied by passing the steel through a molten bath of zinc at a high temperature. A coil to coil process steel sheets from 0 010 to 1 70 inches 0 25 mm to 4 30 mm thick and up to 72 inches 1 830 mm wide is passed as a continuous ribbon through cleaning baths and molten zinc at speeds up to 600 feet per minute.

Continuous sheet galvanizing is also a hot dip process but is only applied to steel sheet strip and wire. View full excess secondary inventory list. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc. Hot dip galvanized steel known as zincgrip steel is continuously coated on both sides with a zinc coating.

Alliance steel s hot dipped galvanized steel sheet and coil service capabilities include slitting shearing blanking degreasing and brushing stretcher leveling and metallurgical support. Hot dip galvanization is a form of galvanization. Several designs of continuous lines have been used. When exposed to the atmosphere the pure zinc zn reacts with oxygen o 2 to form zinc oxide zno which further reacts with carbon dioxide co 2 to form zinc carbonate znco 3 a usually dull grey fairly strong material that protects.
