In most environments, our aluminum-zinc coated steel offers 2-4 times better corrosion resistance than equivalent pure galvanized steel sheet (such as ASTM A653 G90). Aluminum provides excellent barrier protection and passivation properties, while zinc provides sacrificial anodic protection.
Excellent Heat and Oxidation ResistanceCan withstand continuous operating temperatures up to 315°C (600°F) without losing surface luster or protection. Suitable for even higher temperatures for short periods.
High Heat ReflectivityThe silver-gray surface provides approximately 75% heat reflectivity, contributing to building energy efficiency and thermal management.
Economic EfficiencyWhile unit price may be slightly higher, the extended lifespan and superior performance result in more competitive total life-cycle costs.
| Industry | Applications |
|---|---|
| Construction Industry | Roofing panels, wall panels, ventilation ducts, garage doors |
| Household Appliances | Water heater liners, oven shells, microwave ovens, air conditioning ventilation systems |
| Industrial Sector | Heat-resistant or corrosion-resistant components, grain silos, industrial furnace shells |
| Automotive Industry | Exhaust systems, mufflers, and other heat-resistant components |
To ensure seaworthy transportation and product protection, we employ comprehensive packaging solutions including anti-rust oil film, waterproof kraft paper, galvanized iron sheet wrapping, and steel pallets with edge protectors.
GL (Galvalume): Coated with aluminum-zinc alloy. Provides 3 to 6 times better corrosion resistance than GI and superior heat reflectivity.
