Hot Dipped Galvanized Sheet Metal

One of the types most frequently used today has a continuous anneal section.

Hot dipped galvanized sheet metal.

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. 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. 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.

It is the process of coating iron and steel with zinc which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 c 840 f.

Several designs of continuous lines have been used. Continuous sheet galvanizing is also a hot dip process but is only applied to steel sheet strip and wire.

Hot dip galvanization is a form of galvanization. The finish is applied by passing the steel through a molten bath of zinc at a high temperature. View full excess secondary inventory list. Hot dip galvanized steel known as zincgrip steel is continuously coated on both sides with a zinc coating.
