Engineered for elevated thermal operating conditions, our heat resistant aluzinc coated steel provides continuous service durability at temperatures up to 315°C without discoloration or scaling. Featuring an aluminum-rich dendritic matrix, it offers high radiant heat reflection for furnace liners and automotive exhaust shields.
Supported by the industrial manufacturing background of Winroad Group, Authentic Steel produces specialized heat resistant aluzinc coated steel engineered to perform flawlessly under elevated operating thermal environments. Operating from Tianjin since 1994 and exporting to commercial buyers across 78 countries, our continuous hot-dip alloy lines apply an optimized 55% aluminum metallic layer that demonstrates extraordinary thermal endurance. Unlike standard galvanized steel that experiences rapid surface oxidation, discoloration, and peeling above 200°C, our heat-resistant galvalume coils withstand continuous thermal exposure up to 315°C without compromising structural integrity or protective coating adhesion.
The aluminum-rich dendritic outer surface exhibits a high thermal reflectivity coefficient, bouncing away up to 80% of incident radiant heat. This thermal barrier protects the underlying core steel substrate from heat fatigue and surface scaling, making it the premier material choice for industrial heat exchangers, oven inner liners, heating duct enclosures, barbecue grill housings, and automotive exhaust heat shields. Furthermore, its smooth passivated surface resists oil absorption, making it easy to clean in appliance fabrication.
