Hot-dip galvanised steel coil (GI) is made by passing a fully hardened steel sheet, which has undergone a pickling and rolling process, through a zinc pot, thereby coating the surface with a zinc film. Due to the properties of zinc, it offers excellent corrosion resistance, paintability and workability. Typically, the process and specifications for hot-dip galvanised steel sheet and galvanised steel coil are essentially the same.

Galvanised steel coil applications:

Galvanised steel coils are used in a wide range of applications and have the advantage of a long corrosion protection period. It is mainly used as a building and substrate for household appliances, office panels, roof panels, automotive panels, and pre-painted steel coils.

Automotive Steel Sheet

　　To use automotive steel plates must first be stamped and formed, where the plates are stamped into parts of the desired shape and size.

　　Spot welding, as an important welding method for joining thin plates, has a wide range of applications in manufacturing, especially in the automotive industry.

Galvanised Roof Sheet

　　The performance requirements for galvanised roof sheets mainly include the mechanical properties of the material (tensile strength, yield strength, elongation), coating properties (coating type, coating thickness and coating adhesion).

Household Office Galvanised Sheet

　　Including air conditioners, washing machines, refrigerators, photocopiers, etc. Household galvanised sheet is mainly used for general forming applications and stamping.

　　PrePainted Steel Base Metal Substrates

　　Another use for galvanised steel coils is as a substrate for pre-painted steel coils. Pre-painted steel coils are more durable than galvanised coils as they have a polyethylene coating.
