Product Description
Product Overview
ASTM A792 Hot Dipped Galvalume Steel Coil is a premium aluminum-zinc coated steel material offering exceptional corrosion resistance and thermal performance for demanding industrial applications.
Coating Specifications
Composition & Grades
Standard coating composition: 55% aluminum, 43.4% zinc, and 1.6% silicon. Silicon enhances coating adhesion and prevents excessive alloying with the steel substrate.
Coating Weight Options
- AZ60: 60g/m² coating weight
- AZ100: 100g/m² coating weight
- AZ150: 150g/m² coating weight
Key Performance Features
- Superior corrosion resistance: 2-6 times more durable than traditional galvanized steel, especially in salty or humid environments
- High-temperature resistance: withstands continuous exposure up to 315°C (600°F)
- Excellent solar reflectivity: reflects approximately 75% of solar radiation for improved energy efficiency
- Enhanced formability: suitable for deep drawing, bending, and roll forming applications
Material Comparison
| Property | Aluminum-Zinc Coated (AZ) | Galvanized Steel (GI) |
|---|---|---|
| Corrosion Resistance | Excellent (Al + Zn synergy) | Good (depends on Zn thickness) |
| Cost | 10-20% higher than GI | Lower cost |
| Heat Resistance | Up to 315°C | Up to 200°C |
| Appearance | Bright silver, more reflective | Dull gray, prone to white rust |
