HUIYI-PPGL introduces its advanced Z30-Z275 CGLCC Prepainted Galvalume Steel Coil, engineered specifically for the building industry's most challenging environments. This product line represents a significant step forward in protective metal cladding, featuring a substantially heavier zinc-aluminum coating range from Z30 to Z275 grams per square meter.
The core performance advantage lies in its exceptional long-term corrosion resistance. The dense Galvalume (55% Al-Zn alloy) substrate provides a robust sacrificial barrier, making it an optimal choice for coastal infrastructure, industrial facilities, and buildings in high-humidity regions where material integrity is critical. This heavy coating, particularly at grades of Z60 and above, offers superior protection against salt spray and chemical exposure compared to standard galvanized products.
Beyond corrosion protection, these coils are designed for versatility in construction applications. They serve as the primary material for industrial and commercial building envelopes, including wall and roof cladding for factories and warehouses. The product is also ideal for use as the exterior skin in insulated sandwich panels and for high-wear architectural elements like gutters and flashings. Available with PE, PVDF, or HDP paint finishes in standard RAL or custom colors, the coils combine durability with aesthetic flexibility.
Supported by certifications including SGS, BV, and ISO9001, the Z30-Z275 series is packaged for global supply, featuring VCI anti-rust paper, waterproof PE film, and ISPM15-certified wooden pallets for export. This product offers a calculated return on investment for projects where lifecycle cost and minimal maintenance are paramount.
