AZ180 Heavy Coated Galvalume Steel Coil For Coastal Industrial Roofing
Our AZ180 Heavy Coated Galvalume Steel Coil is engineered for coastal and heavy industrial roofing applications where salt spray and pollutants cause relentless corrosion. Featuring a 55% aluminum-zinc alloy coating (AZ180, 180 g/m²), this product combines aluminum's barrier protection with zinc's sacrificial defense to deliver 4-6 times longer service life than standard galvanized steel, with documented field warranties up to 50 years. It withstands sustained temperatures up to 315°C (600°F). For coastal industrial roofing requiring maximum corrosion protection and minimal lifecycle cost, AZ180 is the ultimate long-term solution.
