G30 0.6mm Dx51d Hot Dip Galvanized Steel Coil

G30 galvanized steel is characterized by its specific coating weight, which represents a total zinc coating weight of approximately 90 grams per square meter. The galvanizing process involves dipping the steel in molten zinc to provide a protective layer that enhances its resistance to corrosion. This coating weight is typically used in applications requiring moderate corrosion protection, and this steel is commonly used in a variety of construction, automotive, and manufacturing applications. The name "G30" reflects the amount of zinc applied which is 90G per square meter, helping to improve the durability and service life of the steel in corrosive environments.

 

The purpose of galvanizing is to provide corrosion resistance to the underlying steel. The higher the G number, the greater the amount of zinc applied, and consequently, the higher the level of corrosion protection. G30 is a relatively light coating weight, suitable for applications where moderate corrosion resistance is sufficient. The choice of coating weight depends on the intended use and the level of protection required for the specific environment in which the steel will be deployed.
