G300 Az Hot Dipped Galvalume Steel Sheet in Coils

 

G300+AZ steel is a structural-grade, hot-dipped Aluzinc/Galvalume coated steel with a minimum yield strength of 300 MPa. It features a coating of 55% aluminum, 43.5% zinc, and 1.5% silicon, providing superior corrosion resistance and high heat reflectivity, making it ideal for roofing, cladding, and roll-forming applications.

Thickness of G300GD+AZ hot aluminum zinc steel plate: 0.22 to 1.30mm

Width of G300GD+AZ hot aluminum zinc steel plate:700 to 1250mm

Length of G300GD+AZ hot aluminum zinc steel plate:1000 to 6000mm

Inner diameter ofG300GD+AZ steel strip:508mm

The price of S300GD+AZ is also various from different surface. There are two common surface
