Hot Dipped Galvanized Sheet Metal

Cold reduced sheet steel material in coil form hot rolled pickled is sometime used is uncoiled and passed continuously through the galvanizing line equipment.

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

This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.

The finish is applied by passing the steel through a molten bath of zinc at a high temperature.

The hot dip process pioneered by ak steel provides a tight metallurgical bond between the steel and the 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. Several designs of continuous lines have been used. Hot dip galvanized steel known as zincgrip steel is continuously coated on both sides with a zinc coating.
