제품 설명
ASTM A792 Certified Galvalume Steel Coil For Architectural
Our ASTM A792 Certified Galvalume Steel Coil is engineered for superior performance in architectural applications. Featuring a 55% aluminum-zinc-silicon coating (55% Al, 43.4% Zn, 1.6% Si) this coil provides 2-6 times better corrosion resistance than standard galvanized steel. The hot-dip process creates a metallurgical bond that offers durable protection, with a service life of 20-25 years in normal environments. Ideal for roofing, cladding, and structural components, it also exhibits excellent heat resistance (up to 315°C without discoloration) and high thermal reflectivity (over 75%). Certified to ASTM A792 and supported by ISO 9001 quality management, this coil ensures reliability for demanding architectural projects globally.
