The 3003 aluminum coil (0.45–0.9 mm thickness, 1250 mm standard width, PE or PVDF coated) is the most widely used & cost-effective alloy for modern metal roofing sheets, panels, standing seam systems, corrugated profiles, and architectural cladding.
It is the first-choice material for roofing due to:
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)
Coating system
PE (indoor/general): 20–25 μm polyester, good UV & corrosion resistance,PVDF (coastal/extreme): 25–35 μm fluorocarbon (Kynar 500® equivalent), 40-year warranty,Gloss: 60–80 GU (high-gloss standard),Colors: RAL classic (white, gray, silver) + custom matching.

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 |

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
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
Upcoming Applications
Floating city modular roofing
Mars habitat radiation-reflective roofs
Zero-energy building integrated solar roofs
High-speed rail station curved metallic roofs
Q1: Why choose 3003 over 3105 or 5052 for roofing?
A: 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.
Q2: PVDF vs PE – which is better for my project?
A: PVDF (fluorocarbon) for coastal, high-UV or desert (40-year warranty, ΔE ≤1). PE for inland/general use (20–25 years, more economical).
Q3: What is the warranty & salt-spray performance?
A: PVDF: 40-year color/film warranty, ≥5000 h salt-spray. PE: 20–25 years, ≥2000 h. We provide full warranty certificate.
Q4: Minimum order quantity & lead time?
A: MOQ 3-5 tons (depending on color/thickness); standard lead time 15–25 days. Sample coils free (freight collect).
Q5: Can you provide color samples & matching?
A: Yes – RAL classic stock + custom matching within 48 h. Send RAL code or physical sample for exact match.
