Why Choose Aluzinc Steel?
Aluzinc combines a steel substrate with an aluminum-zinc metallic coating to provide a useful balance of strength, corrosion resistance, surface durability and heat resistance.
Corrosion Resistance
The aluminum-zinc coating provides protective performance for applications exposed to atmospheric conditions.
Heat Resistance
Aluminum-zinc coated steel is suitable for applications where improved heat resistance is required compared with conventional zinc-coated products, subject to the specific service conditions and product specification.
Long-Term Building Performance
Aluzinc is commonly selected for roofing, cladding and building-envelope applications where long service life and reduced maintenance are important design considerations.
Excellent for Roll Forming
Appropriate Aluzinc grades can be selected for roll-forming and profiling operations used to manufacture roofing and cladding products.
Attractive Metallic Finish
The characteristic Aluzinc surface provides a bright metallic appearance suitable for many construction and industrial applications.
Aluzinc vs Galvanized Steel
Aluzinc and galvanized steel are both metallic-coated steel products, but their coating systems are different.
| Feature | Aluzinc Steel | Galvanized Steel |
|---|---|---|
| Main coating | Aluminum-zinc alloy | Zinc |
| Common specification | ASTM A792/A792M | ASTM A653/A653M |
| Common use | Roofing, cladding, PEB, panels | Construction, fabrication, general applications |
| Coating system | Aluminum-zinc alloy | Zinc |
| Heat performance | Suitable for applications requiring heat resistance, subject to specification | Application dependent |
| Surface | Metallic Al-Zn appearance | Zinc/spangle appearance |
The correct product depends on the application, environment, fabrication method, design requirements and project specification.
Aluzinc for UAE & GCC Climate
The UAE and wider GCC region present demanding environmental conditions, including high temperatures, strong solar exposure, dust and, in coastal locations, salt-laden atmospheric conditions.
