Aluminum Alloy 5005 Aluminum Sheet for Curtain Wall Panels | Thickness 2.0–4.0 mm | Width 1500 mm | PVDF Fluorocarbon Coating

Introduction                                                

The 2.0–4.0 mm 5005 PVDF coated aluminum sheet is currently the preferred high-strength specification for solid metal curtain wall panels, spandrel areas, column covers, large-area veneer and impact-resistant facade systems in modern high-rise & landmark architecture.

Compared to 3003/3105 (softer) or 5083 (stronger but more expensive), 5005 delivers the optimal balance for most demanding curtain wall projects:

Mg alloying (0.5–1.0%) → 20–30% higher strength than 3003

Excellent anodizing & coating adhesion

Superior flatness & rigidity in thick gauges

Cost-effective alternative to 5083/5454 while meeting AAMA 2605 & EN 1396 standards

Coating system:25–35 μm premium PVDF fluorocarbon (Kynar 500® / Hylar 5000® equivalent),3-layer structure (primer + color + clear topcoat),Gloss: 30–80 GU (matte to high-gloss),Warranty: 40 years color fade (ΔE ≤1), chalking (≥8), gloss retention (≥50%), film integrity

FAQ (USA/Europe/Middle East/Asia Buyers)

Q1: Why choose 5005 over 3003 or 5052 for curtain wall panels?

A: 5005 offers ~20–30% higher strength than 3003 (better wind-load & impact resistance) while being 15–25% cheaper than 5052. It is the cost-performance sweet spot for most high-rise & coastal facade projects.

Q2: What is the actual 40-year PVDF warranty coverage?

A: Covers fade (ΔE ≤1), chalking (rating ≥8), gloss retention (≥50%), film integrity (no peeling/cracking). Full warranty certificate, AAMA 2605 Level 3 compliance & Florida exposure data provided.

Q3: Can you provide salt-spray test report & wind-load calculation?

A: Yes — 5000 h neutral + acetic salt spray (ISO 9227/ASTM B117) passed. Wind-load engineering support & calculation reports available for your panel size & fixing system.

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

A: MOQ 3 tons (depending on color); standard colors 15–25 days; custom RAL match 25–35 days. Sample sheets/coils free with freight collect.

Q5: How does 5005 perform in extreme coastal/high-wind areas?

A: PVDF-coated 5005 passes 5000 h salt-spray; 2.5–3.0 mm thickness handles wind loads up to 200–250 km/h (depending on panel size & fixing). Coastal exposure & wind-load data available.

Q6: Is 5005 suitable for large-format panels without oil-canning?

A: Yes — 5005 has excellent flatness & low thermal expansion. We recommend H24 temper + tension leveling. Large-panel samples & forming suggestions provided.
