3003 Alloy Prepainted Aluminium Coil with 0.45–0.9mm Thickness and 1250mm Width for Roofing Sheets

Aluminum Alloy 3003 Coil for Roofing Sheets

The 3003 aluminum coil (0.45-0.9 mm thickness, 1250 mm standard width, PE or PVDF coated) is the most widely used and cost-effective alloy for modern metal roofing sheets, panels, standing seam systems, corrugated profiles, and architectural cladding.

Primary Roofing Applications

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

Why Choose 3003 Aluminum for Roofing?

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)

Core Benefits

Advantage	Detailed Description
40-Year Fade & Gloss Retention (PVDF)	ΔE ≤1 after 40 years (ASTM D2244), virtually no chalking
Extreme Corrosion Resistance	≥5000 h neutral + acetic salt spray (coastal & polluted areas)
Lightweight Design	0.7 mm ≈ 1.89 kg/m² vs 0.5 mm steel ≈ 3.9 kg/m² → ~52% lighter
Outstanding Roll-Forming & Profiling	2T bend without cracking, ideal for standing seam & corrugated
Energy Efficiency (Cool Roof Option)	High-TSR white (TSR >80%) → 15-25% lower cooling load
ECO Friendly	98% recycling rate, 96% lower CO₂ vs steel roofing

Industry Trends

Thinner gauges (0.4-0.6 mm) for weight-critical green roofs
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

Frequently Asked Questions

Why choose 3003 over 3105 or 5052 for roofing?

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 vs PE - which is better for my project?

PVDF (fluorocarbon) for coastal, high-UV or desert (40-year warranty, ΔE ≤1). PE for inland/general use (20-25 years, more economical).

What is the warranty & salt-spray performance?

PVDF: 40-year color/film warranty, ≥5000 h salt-spray. PE: 20-25 years, ≥2000 h. We provide full warranty certificate.

Minimum order quantity & lead time?

MOQ 3-5 tons (depending on color/thickness); standard lead time 15-25 days. Sample coils free (freight collect).

Can you provide color samples & matching?

Yes - RAL classic stock + custom matching within 48 h. Send RAL code or physical sample for exact match.
