Product Description
Aluminum Alloy 3105 Color-Coated Aluminum Sheet
Thickness 1.2–3.0 mm | Custom Width | Fluorocarbon System (PVDF) for Building Exterior Walls
Product Overview
The 3105 PVDF color-coated aluminum sheet (thickness 1.2-3.0 mm) has become a mainstream choice in the international high-end architectural metal facade and cladding market. Compared with 3003 alloy, 3105 offers higher strength and better anti-penetration performance while maintaining excellent coating adhesion and weather resistance.
Premium Coating System
- 25-35 μm premium PVDF fluorocarbon (Kynar 500® / Hylar 5000® or equivalent)
- 3-layer structure (primer + color + transparent topcoat)
- Standard color fastness warranty: 40 years

Core Benefits
| Advantage | Detailed Description |
|---|---|
| 40-Year Color & Gloss Retention | ΔE ≤ 1 after 40 years (ASTM D2244) |
| Exceptional Corrosion Resistance | ≥5000 h neutral + acetic acid salt spray (best among 3xxx series) |
| Higher Mechanical Strength | Tensile strength 20-30% higher than 3003 → better wind pressure resistance |
| Outstanding Formability | 2T-3T bend without paint cracking; suitable for complex cassettes & curves |
| Significant Weight Reduction | 1.5 mm aluminum ≈ 4.05 kg/m² vs 0.8 mm steel ≈ 6.3 kg/m² → ~35% lighter |
| Excellent Cool Roof Potential | Optional high-TSR white (TSR > 80%) → reduces air-conditioning load 15-25% |

International Applications
- Ultra-high-rise & landmark buildings → curtain wall back panels, spandrel panels, column covers
- Coastal & marine city projects → high-salt spray areas (Dubai, Miami, Singapore, Sydney, Qatar)
- Typhoon & hurricane zones → Southeast Asia, Caribbean, East Coast USA, Southern China
- Airport & transportation hub → terminal roof & wall systems
- Cultural & museum buildings → large-area metal facades requiring long color stability
Industry Trends
- Thinner + Stronger → 0.9-1.0 mm 3105/3004 becoming mainstream for high-rise ventilated systems
- Cool Roof 2.0 → high solar reflectance (TSR > 85%) + low-e pigments standard
- Digital-print metal façades → stone, concrete, wood-grain textures on PVDF base
- Circular economy acceleration → 95%+ recycled content 3105 coils with full traceability
- BIPV integration → color-matched thin-film solar + PVDF roofing/cladding systems
- Extreme climate adaptation → 50-year PVDF warranty becoming common
