What are the features of hot-dip galvanized steel coils? Hot-dip Galvanized steel sheets are widely used in modern society, such as automobile parts,computer case, architecture material, household appliance and so on. To meet the multiple requirements, the specification of hot-dip G...

The figure below shows 11 processes for making a steel coil for the manufacturing industry.

This kind of galvanized steel coil / sheet can be subjected to simple bending or moderate drawing. It can be bent flat on itself in any direction at room temperature.

Commercial Steel (CS Types A, B, and C)Forming Steel (FS Types A and B)Deep Drawing Steel (DDS Types A and C)Extra Deep Drawing Steel (EDDS)Structural Steel (SS) – further designated by Grades (33,37,40,50,80)High Strength Low Alloy Steel (HSLAS)

The purpose of the zinc is to provide excellent protection against corrosion of the base steel. The zinc is a sacrificial barrier to protect the base steel. The zinc will sacrifice itself and will eventually disappear before the base metal will start to corrode.

Hot Dipped Galvanized is normally a cold rolled steel (depending on gauge, may be a hot rolled base) which has been given a process by which a coating of zinc has been applied to the surface. This zinc has excellent adherence to the surface of the base steel.
