prepaintedHot-dip galvanizing is the process of coating steel with a thin layer of zinc by passing the metal through a bath of molten zinc. The zinc coating prevents oxidation of the protected metal, as it increases its corrosion resistance, contributing to its longevity.

Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface usually called a “spangle”. Common uses for galvanized steel are roofing and walling, safety barriers, handrails, consumer appliances and automotive body parts. The galvanized steel coils and sheets can also be painted to offer further corrosion protection and provide the material different colors as various applications may require.
