G60 Galvanized Steel Coil uses a coating designation that identifies both the coating type and the coating weight applied to the steel surface. The letter “G” indicates that the coating is galvanized, meaning it is zinc-based, while the number “60” represents the zinc coating thickness and coating weight on the steel coil.

Galvanized steel coil is coated with zinc to provide enhanced corrosion resistance and long-term surface protection. In the manufacturing process of G60 galvanized steel coil, the steel passes through a molten zinc bath during a continuous coating operation. After coating, excess zinc is removed by high-pressure air knives to achieve the required coating thickness and maintain a uniform finish.

The protective G60 zinc coating acts as a barrier that prevents moisture and corrosive substances from reaching the steel substrate, significantly improving the corrosion resistance and durability of the material. As a result, G60 galvanized steel coil offers an extended service life and is widely used in construction, roofing systems, household appliances, automotive components, ventilation equipment, and general industrial applications.
