AA3003 Roller Shutter Prepainted Aluminum Coil Roller Shutter Aluminum Coil
Prepainted aluminum roller shutters have become a mainstream choice for commercial
buildings, industrial plants, and garages due to their lightweight, high strength, corrosion
resistance, and aesthetic durability.
Core Advantages of 3003 Prepainted Aluminum Roller Shutters
① Lightweight Yet Durable
3003 aluminum alloy (Al-Mn series) has low density (2.73g/cm³), making it 50% lighter than
steel shutters, reducing load on tracks and motors.
Tensile strength: 110-145MPa, suitable for wind resistance (withstands 6-8 level winds).
② Superior Corrosion Resistance
Manganese content (Mn≈1.2%) enhances corrosion resistance, passing 500-hour salt spray
tests—ideal for coastal or humid areas.
PVDF coating (or PE coating) provides UV and acid rain resistance, with an outdoor lifespan
of 10-15 years.
③ Aesthetic & Customizable
Customizable finishes: wood grain, solid colors (RAL palette), brushed metal, etc.
Optional ventilation designs (round holes/louvered openings) for light and airflow control.
④ Low Maintenance
No rust-proof painting required; easy cleaning with water.
Recommended Applications
Retail Stores:
1.0mm + PVDF coating with louvered vents for security and display.
Underground Garages:
1.2mm + PE coating, cost-effective and moisture-resistant.
Industrial Warehouses:
1.5mm + reinforced frame for high-frequency use.
Comparison with Traditional Shutters
| Feature | 3003 Color-Coated Aluminum | Steel Roller Shutter | Stainless Steel Shutter |
| Weight | Light (≈15kg/m²) | Heavy (≈25kg/m²) | Medium (≈20kg/m²) |
| Corrosion Resistance | Excellent (500h salt spray) | Requires galvanization (200h) | Excellent (but costly) |
| Noise Level | Low (aluminum rails) | Higher (metal friction) | Moderate |
