Huiyi's Galvalume Coil Offers 5x Better Corrosion Resistance
October 28, 2025
Huiyi announces its breakthrough Hot-Dipped Galvalume Steel Coil DX51D+AZ, engineered to meet the rigorous demands of the global building industry. This advanced material combines superior corrosion resistance with exceptional formability, offering architects and builders a reliable solution for modern construction challenges.
Certified to ISO9001 standards, the coil features a unique aluminum-zinc-silicon alloy coating (55% aluminum, 43.5% zinc, 1.5% silicon) that provides up to 5 times better corrosion protection than conventional galvanized steel. The thermally cured protective layer ensures long-term performance in harsh environments, including coastal areas where salt spray typically accelerates material degradation.
The product's versatility extends across multiple construction applications, from roofing and wall cladding to HVAC systems and interior elements. Available in thicknesses from 0.3-1.5mm and various coating weights (AZ30-AZ275), it offers flexibility for different project requirements. The chromate surface treatment ensures excellent paint adhesion for customized architectural finishes.
With a monthly supply capacity of 5,000 metric tons and efficient 15-30 day delivery terms, we positions this Galvalume coil as a sustainable building solution that aligns with green construction standards through its recyclability and reduced maintenance needs.
