3003 Alloy Prepainted Aluminium Coil with 0.45–0.9mm Thickness and 1250mm Width for Roofing Sheets
- Standing seam & concealed fastener roofs: commercial buildings, warehouses, airports
- Corrugated & trapezoidal roofing: industrial facilities, agricultural buildings
- Architectural cladding & facade panels: high-rise & landmark projects
- Coastal & marine environments: resorts, beachfront structures, offshore platforms
- Extreme climates: desert (Middle East), tropical (Southeast Asia), northern snow-load areas
- Moderate strength (20% stronger than 1100)
- Excellent formability for roll-forming & profiling
- Superior corrosion resistance (especially with PVDF)
- Cost-effective balance vs 3004/3105 (higher strength) or 5052 (more expensive)

- Cool roof coatings → high TSR (>80%) + IR-reflective pigments
- Digital-print roofing → stone/wood textures on PVDF base
- 95%+ recycled content 3003 with CO₂ passport
- BIPV integration → color-matched solar roofing
- 50-year warranty becoming standard in extreme climates
3003 offers the best cost-performance balance for most roofing. 3105 is slightly stronger (better dent resistance), but 3003 is more formable & cheaper. 5052 is overkill (more expensive) unless extreme strength needed.
PVDF (fluorocarbon) for coastal, high-UV or desert (40-year warranty, ΔE ≤1). PE for inland/general use (20-25 years, more economical).
PVDF: 40-year color/film warranty, ≥5000 h salt-spray. PE: 20-25 years, ≥2000 h. We provide full warranty certificate.
MOQ 3-5 tons (depending on color/thickness); standard lead time 15-25 days. Sample coils free (freight collect).
Yes - RAL classic stock + custom matching within 48 h. Send RAL code or physical sample for exact match.
