## 3. Metallurgy & Corrosion Performance: Galvalume Plus® AZ180

### 3.1 Chemical Composition & Galvanic Mechanism
- **55% Aluminum**: Provides a microscopic passivating barrier layer of aluminum oxide that prevents atmospheric oxidization.
- **43.4% Zinc**: Provides sacrificial cathodic protection. If cut, sheared, or drilled, zinc corrodes preferentially to protect exposed core steel edges.
- **1.6% Silicon**: Added to the hot-dip bath to ensure uniform micro-crystalline adhesion between steel substrate and coating layer.
- **Coating Mass**: AZ180 (180 grams per square meter total both sides), ASTM A792 / A792M standard.

### 3.2 Lifespan & Thermal Efficiency
- **Lifespan & Warranty**: 25-year contractual anti-corrosion factory warranty, with 40 to 50 years expected maintenance-free design service life under severe industrial, agricultural ammonia, and coastal marine environments.
- **Solar Reflectance**: High thermal emissivity and solar reflectance index (SRI > 75) repelling up to 80% of incident solar thermal radiation, lowering cooling HVAC energy demands by up to 35%.
