5052 3003 Alloy Color Coated Prepainted Aluminum Coil

Color-coated 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.

• Lightweight Design: Aluminum is only 1/3 the density of steel, reducing door weight by 40%~50%, lowering motor load, and extending service life. Suitable for large doors (up to 6m wide), minimizing track wear.
• Superior Corrosion Resistance: PVDF or polyester coatings withstand 1,000 hours of salt spray testing (ASTM B117), ideal for coastal or chemical environments. No rust maintenance required, with a lifespan of 15~20 years (vs. 8~10 years for steel doors).
• High Strength and Security: Made from 3003/H24 or 5052 aluminum alloy (tensile strength ≥200MPa) with internal reinforcement, achieving wind resistance up to Level 12 (EN 12424). Optional anti-theft features (e.g., pry-resistant edges, multi-point locks) for RC3 security rating.
• Aesthetics and Customization: Available in various colors (RAL chart), wood grain, or brushed metal finishes to match building exteriors. Transparent (with PC slats) or solid designs for light control and privacy.
• Energy Efficiency and Sustainability: 100% recyclable, with production energy consumption only 5% of primary aluminum. Hollow or polyurethane foam-filled structures (U-value ≤0.5 W/m²*K) enhance insulation.
