Corrosion-resistant Aluzinc Coated Steel Coil (AZ150)
description1
description2
With 55% aluminum-zinc alloy coating (AZ150), this product combines aluminum's heat resistance and zinc's cathodic protection, offering 3～6× better corrosion resistance than standard galvanized steel. The substrate undergoes rigorous pretreatment for strong, uniform coating adhesion.
Coating Composition: 55% Al, 43.4% Zn, 1.6% Si
Coating Weight: 60g/m²～180g/m² (both sides)
Thickness: 0.3mm～2.5mm
Width: 1000mm～1250mm
Surface Pattern: Regular spangle, spangle-free, skin-passed
Standards: ASTM A792, GB/T 14978
1. Extended Durability: Over 20 years service life in marine atmospheres.
2. Heat Resistance: Withstands 300°C continuously for high-temperature applications.
3. Cost-Effective: Lower anti-corrosion cost per unit area vs. stainless steel/aluminum.
Solar mounting structures, industrial roofing, grain silos, weather-resistant building envelopes.
Anti-rust paper + steel strapping, or wooden pallet reinforcement to ensure safe transportation.
