S450GD+AZ Galvalume Coil: High Strength & Corrosion Resistance
October 20, 2025
S450GD+AZ Galvalume Steel Coil from Huiyi-GL
Engineered to address the rigorous demands of modern construction, the new S450GD+AZ Galvalume Steel Coil from Huiyi-GL delivers a robust solution for structural applications. This product combines exceptional structural strength with superior long-term corrosion resistance, offering a durable and cost-effective solution for architects, engineers, and builders.
The defining feature of this material is its S450GD steel grade, which guarantees a minimum yield strength of 450 MPa. This high tensile strength makes it an ideal choice for load-bearing components such as purlins, girts, steel trusses, and mezzanine floors in industrial and commercial buildings, ensuring structural integrity and safety.
Beyond its core strength, the coil is protected by a advanced 55% aluminum-zinc-silicon coating (AZ30-AZ150). This Galvalume coating provides a unique dual-defense mechanism: the aluminum forms a robust barrier against corrosion and heat, while the zinc offers sacrificial protection at cut edges. This synergy results in a service life up to four times longer than conventional galvanized steel, significantly reducing maintenance costs, especially in harsh environments.
Available in a versatile 1500mm width and thicknesses from 0.12mm to 2.0mm, the coil is produced to international standards including ASTM A792 and EN 10147. Its compatibility with various surface treatments and a zero-spangle option makes it perfectly suited for both direct exposure and as a high-quality substrate for painted systems.
With a monthly supply ability of 5,000MT, we ensures reliable global delivery, backed by ISO9001 certification. This new S450GD+AZ Galvalume coil is set to become a material of choice for construction projects where longevity, strength, and performance are non-negotiable.
