Aluminum Alloy 3105 Aluminum Coil for Container Side Panels Thickness 0.8–1.0 mm | Width 1220 mm | High Durability Coating (PE / PVDF)

Introduction                                                

The 3105 aluminum coil with high-durability PE/PVDF coating (0.8–1.0 mm thickness, 1220 mm standard width) is currently the fastest-growing specification in the global shipping container industry for side panel skins, interior linings, dry cargo walls and reefer container interiors.

Compared to traditional galvanized steel or thicker aluminum (1.2–1.6 mm), 3105 0.8–1.0 mm achieves the optimal balance for modern container manufacturing:

Significant weight reduction → higher payload capacity

Excellent corrosion resistance in marine & humid environments

Superior roll-forming & profiling performance for corrugated side walls

Competitive cost vs 5052/5083 while delivering 25–30 year service life

Coating system

PE (polyester): 20–25 μm, cost-effective for dry cargo,PVDF (fluorocarbon): 25–35 μm, 3-layer structure, 30-year fade/chalk resistance,Gloss: 30–60 GU (matte to semi-gloss standard)

Warranty: PVDF 30 years / PE 20–25 years (color retention ΔE ≤2)

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

Q1: Why choose 3105 over galvanized steel or 5052 for container side panels?

A: 3105 is ~80% lighter than steel (higher payload), more corrosion-resistant than galvanized in marine environments, and 20–35% cheaper than 5052 while maintaining excellent formability & coating adhesion.

Q2: What is the real salt-spray performance & expected service life?

A: PE coating ≥3000 h, PVDF ≥5000 h (neutral + acetic salt spray). Expected service life 25–30 years (PVDF) / 20–25 years (PE) in global maritime conditions. Full test reports & Florida exposure data available.

Q3: Can the coil be corrugated / profiled without paint cracking?

A: Yes — 3105 has excellent formability (2T bend radius). We recommend H24 temper + proper tension leveling to eliminate oil-canning. Profiled samples & forming suggestions provided.

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

A: MOQ 3-5 tons (depending on color); standard white/gray 15–25 days; custom RAL match 25–35 days. Sample coils free with freight collect.

Q5: How does 3105 perform in extreme marine & tropical climates?

A: PVDF-coated 3105 passes 5000 h salt-spray; no chalking or delamination in 90%+ humidity reefer interiors. Humidity chamber & salt-spray test data available.

Q6: Is the coating resistant to cleaning agents & graffiti?  

A: Yes — passes resistance to common marine cleaners & graffiti removal (tested per ASTM D1308). Anti-graffiti nano topcoat optional for extra protection.
