Introduction

The 3105 prepainted aluminum coil (0.6–1.2 mm thickness, 900–1220 mm width) is currently the most popular mid-range architectural cladding material worldwide for ventilated facades, rainscreen systems, cassette panels, solid metal veneer and exterior wall cladding.

Compared with 3003 (softer) or 5052 (stronger but more expensive), 3105 delivers the optimal balance for most modern facade projects:

20–25% higher strength than 3003 → better wind-load & dent resistance

Outstanding paint adhesion & long-term flatness,Excellent cost-performance ratio for mid-to-high-rise & commercial buildings,Superior coastal & urban pollution resistance with PVDF coating.

Coating system

PE (polyester): 20–25 μm, cost-effective for inland / moderate climates,PVDF (fluorocarbon, Kynar 500® equivalent): 25–35 μm, 3-layer structure, 30-year fade/chalk warranty,Gloss: 30–70 GU (matte to semi-gloss standard),Warranty: PVDF 30 years / PE 20–25 years (color retention ΔE ≤1)

FAQ – Common Buyer Questions (USA/Europe/Middle East/Asia Buyers)

Q1: Why choose 3105 over 3003 for wall cladding?

A: 3105 has ~20% higher yield strength → better wind-load resistance & dent protection, while keeping excellent formability & paint adhesion. 3003 is softer & cheaper but less rigid for high-rise or high-wind areas.

Q2: What is the real 30-year warranty coverage for PVDF coating?

A: Covers color fade (ΔE ≤1), chalking (rating ≥8), gloss retention (≥50%), film integrity (no peeling/cracking). Full warranty certificate & third-party exposure data (Florida/Arizona) provided.

Q3: Can you provide salt-spray test report & AAMA 2605 compliance?

A: Yes — 5000 h neutral + acetic salt spray (ISO 9227/ASTM B117) passed, AAMA 2605 Level 3 for PVDF. Full test reports & color fastness data available.

Q4: Minimum order quantity & lead time for custom colors?

A: MOQ 5–10 tons (depending on color); standard colors 15–25 days; custom RAL match 25–35 days. Sample coils (small roll) free with freight collect.

Q5: How does 3105 perform in coastal/high-wind areas?

A: PVDF-coated 3105 passes 5000 h salt-spray; 1.0 mm thickness handles wind loads up to 150–200 km/h (depending on panel size & fixing). Wind-load calculation & engineering support provided.

Q6: Is 3105 coil suitable for rainscreen without oil-canning?

A: Yes — 3105 has excellent flatness & low thermal expansion. We recommend H24 temper + tension leveling to eliminate oil-canning risk. Samples tested on your profile available.
