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.
