S450GD+AZ Galvalume Steel Coil 610mm for Construction Material
Product Description
Engineered for superior structural performance, our S450GD+AZ Galvalume Steel Coils are high-strength substrates coated with a 55% aluminum-zinc-silicon alloy. Unlike standard Galvalume, this coil is defined by its S450GD grade, which provides a minimum yield strength of 450 MPa, making it exceptionally strong and load-bearing. Specifically designed for demanding construction frameworks, this product combines the durability of Galvalume with the rigidity of high-tensile steel, offering a robust, long-lasting solution for structural applications.

Applications
This high-strength S450GD+AZ Galvalume coil is specifically engineered for construction applications where load-bearing capacity and corrosion resistance are critical.
Structural Building Framing: Ideal for primary and secondary structural components like purlins, girts, and steel trusses in industrial warehouses and commercial buildings.
Heavy-Duty Support Systems: Used in the fabrication of load-bearing platforms, mezzanine floors, and walkways, where its high yield strength ensures safety and longevity.
External Cladding and Roofing Substrates: Serves as a durable base for insulated panels and standing seam roofs, providing a strong, rust-resistant foundation that withstands harsh weather.
Infrastructure and Guardrails: Perfect for highway sound barriers, security fencing panels, and other infrastructure projects requiring a combination of strength, durability, and minimal maintenance.
Packing and Shipping
To ensure the integrity of the high-strength edges and surface, each coil is protected with VCI anti-rust paper, reinforced waterproof PE film, and custom steel-edge protectors on wooden pallets (max 10 tons). We ship globally via FOB/CIF from main Chinese ports, with reliable delivery timelines.
FAQ
Q: What is the main advantage of S450GD+AZ over DX52D+AZ?
A: The key difference is strength. S450GD+AZ has a minimum yield strength of 450 MPa, making it a structural grade ideal for load-bearing components. DX52D is a commercial grade with higher formability but lower strength, suited for non-structural applications.
Q: How does the AZ30-AZ150 coating weight range benefit my construction project? A: The AZ30-AZ150 coating range allows for precise cost-to-performance optimization. Lighter coatings (e.g., AZ30-AZ70) are ideal for interior structural members or less aggressive environments, offering excellent value. Heavier coatings (e.g., AZ100-AZ150) provide maximum longevity for exposed structural components, safeguarding your project against corrosion for decades.
Q: Is this coil suitable for direct exposure without painting?
A: Yes, the Galvalume coating provides excellent corrosion resistance on its own. However, the zero-spangle finish is also ideal if you plan to apply a paint system for additional aesthetics or specific environmental protection.
