| Width | 600-1500 mm (customizable) |
| Surface Finish | Smooth (standard), matte, or embossed (spangled for anti-slip) |
Key Performance Features
Superior Corrosion Resistance
2-6 times more resistant than regular galvanized steel (GI), particularly in harsh environments such as coastal and industrial areas. Aluminum forms a protective oxide layer (Al₂O₃), while zinc provides sacrificial protection.
High Temperature Performance
Withstands temperatures up to 300°C long-term and short-term exposure to 600°C, making it ideal for chimneys, oven parts, and high-temperature applications.
Excellent Solar Reflectivity
High solar reflectance of approximately 75%, suitable for roofing systems and solar equipment installations.
Outstanding Formability
Excellent performance for stamping and bending operations, though coating abrasion may occur during severe processing conditions.
Product Advantages
Durability: Protected from corrosion in most end-use applications
Severe Conditions Performance: Superior performance in most atmospheric conditions
Sustainability: 100% recyclable with extended service life
Flexibility: Can be formed into a wide variety of end-use applications
Low Maintenance: Easy to clean surface that is virtually maintenance-free
Industrial Applications
55% Aluminum-Zinc Alloy Coated Steel products are ideal for applications requiring long-term, maintenance-free corrosion protection. Common applications include roofing and wall panel systems, metal buildings, fascia, and various architectural applications.
