Product Description
S350GD+AZ150 Long Service Life Galvalume Steel Coil For Roof & Wall
Our S350GD+AZ150 Galvalume Steel Coil is a premium high-strength structural steel product engineered for demanding roofing and cladding applications where longevity and durability are paramount. The designation S350GD signifies a structural steel with a minimum yield strength of 350 MPa, providing excellent load-bearing capacity for building frames and supports. It is coated with a 150g/m² aluminum-zinc alloy layer (AZ150) through a continuous hot-dip process. This unique Galvalume coating, typically composed of 55% aluminum and 43.4% zinc, offers superior corrosion resistance by combining the barrier protection of aluminum with the sacrificial protection of zinc. The result is a coil product that delivers exceptional service life—often 2 to 4 times longer than standard galvanized steel in many environments—making it an optimal, cost-effective solution for constructing durable and low-maintenance building envelopes.
