Alu-zinc Alloy Coated Steel sheet-galvalume China Supplier Aluzinc Sheet
Alu-Zinc Alloy Coated Steel Sheet — Galvalume China Supplier
Alu-Zinc Alloy Coated Steel Sheet, commonly known as Galvalume®, is a premium corrosion-resistant steel product featuring a coating composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. This unique alloy coating provides exceptional resistance to rust, heat, and weathering, making it ideal for roofing, wall cladding, HVAC ductwork, agricultural buildings, industrial structures, and outdoor electrical enclosures. Galvalume sheets outperform traditional galvanized steel in lifespan — often lasting 2-4 times longer — while offering superior heat reflectivity and formability.
Baobin Company is a trusted China-based supplier and manufacturer of high-quality Aluzinc (Galvalume) steel sheets. We specialize in producing sheets that meet international ASTM A792, JIS G3321, and EN 10346 standards. Whether you require standard commercial dimensions or fully customized thicknesses, widths, coil lengths, coating weights, or surface finishes (regular spangle, minimized spangle, or anti-fingerprint), our advanced production lines and strict quality control ensure consistent performance and durability. We support OEM/ODM projects and provide technical consultation to help you select the optimal coating and substrate combination for your specific environmental and structural requirements.
