Key Advantages
Superior Corrosion Resistance
In most environments, our aluminum-zinc coated steel offers 2-4 times better corrosion resistance than equivalent pure galvanized steel sheet (such as ASTM A653 G90). Aluminum provides excellent barrier protection and passivation properties, while zinc provides sacrificial anodic protection.
Excellent Heat and Oxidation ResistanceCan withstand continuous operating temperatures up to 315°C (600°F) without losing surface luster or protection. Suitable for even higher temperatures for short periods.
High Heat ReflectivityThe silver-gray surface provides approximately 75% heat reflectivity, contributing to building energy efficiency and thermal management.
Economic EfficiencyWhile unit price may be slightly higher, the extended lifespan and superior performance result in more competitive total life-cycle costs.
Applications

| Automotive Industry | Exhaust systems, mufflers, and other heat-resistant components |
Packaging & Shipping
To ensure seaworthy transportation and product protection, we employ comprehensive packaging solutions including anti-rust oil film, waterproof kraft paper, galvanized iron sheet wrapping, and steel pallets with edge protectors.
Frequently Asked Questions
What is Aluminum-Zinc Coated Steel?
It is a steel sheet coated with an alloy consisting of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This unique composition combines the corrosion resistance of aluminum with the sacrificial protection of zinc.
What is the difference between GI (Galvanized) and GL (Galvalume)?
GI (Galvanized): Coated with pure zinc. Offers excellent sacrificial protection but has shorter lifespan in corrosive environments.
GL (Galvalume): Coated with aluminum-zinc alloy. Provides 3 to 6 times better corrosion resistance than GI and superior heat reflectivity.
GL (Galvalume): Coated with aluminum-zinc alloy. Provides 3 to 6 times better corrosion resistance than GI and superior heat reflectivity.
What surface finishes are available?
We offer three main surface types:
• Regular Spangle: Standard crystalline pattern
• Minimized Spangle: Fine, uniform surface appearance
• Zero Spangle: No visible pattern, ideal for painting applications
• Regular Spangle: Standard crystalline pattern
• Minimized Spangle: Fine, uniform surface appearance
• Zero Spangle: No visible pattern, ideal for painting applications
Can it be painted?
Yes. We supply Pre-Painted (PPGI/PPGL) coils with various coatings including polyester, silicon modified polyester (SMP), or PVDF (fluorocarbon). We also supply bare (unpainted) coils suitable for post-painting processes.
What thicknesses and widths are available?
Thickness: 0.12mm to 2.0mm (custom sizes available)
Width: 600mm to 1,250mm (custom sizes available upon request)
Width: 600mm to 1,250mm (custom sizes available upon request)
What are the common applications?
• Construction: Roofing sheets, wall cladding, gutters, sandwich panels
• Home Appliances: Air conditioner covers, refrigerator back panels, ovens
• Industrial: Automotive parts, agricultural equipment
• Home Appliances: Air conditioner covers, refrigerator back panels, ovens
• Industrial: Automotive parts, agricultural equipment
How is the coil packed for export?
For seaworthy transportation protection, we use anti-rust oil film, waterproof kraft paper, galvanized iron sheet wrapping, and steel pallets with edge protectors to ensure product integrity during shipping.
