Side Wall & End Wall Panels

Side and end wall panels form the interior vertical surfaces of passenger cabins. These panels use honeycomb-cored sandwich construction or FRP composites to deliver a rigid yet lightweight finish. A wide range of finishes (paint, lacquer, HPL, wood/stone vinyl) can be applied for aesthetic appeal. Materials are chosen for high fire resistance and impact toughness, with options for sound-damping backing. The panels provide a smooth, durable barrier that hides wiring and insulation, enhancing thermal and acoustic comfort.

Key Features

Honeycomb Core Construction: Aluminum (or Nomex) honeycomb core with aluminum alloy skins provides ultra-lightweight strength.
Fireproof & Acoustic: Panels are inherently fire-resistant and anacoustic (sound-absorbing).
Decorative Finishes: High-pressure laminate (HPL) or gel-coat surfaces available in multiple colors/patterns, resistant to wear, scratching and moisture.
Precision Fabrication: Large-format panels (up to ~2.2×12.0 m) allow fewer seams; sizes can be custom-cut.
Integrated Support: Built-in runners or clips allow quick mounting; can accommodate cabling or fixtures behind panels.

Benefits

Weight Reduction: Lighter than conventional panels, saving energy and allowing higher passenger loads.
Durability: Tough surfaces resist daily wear, impacts and vandalism, extending service life.
Cleanability: Smooth, sealed finishes make cleaning easy and improve cabin hygiene.
Enhanced Comfort: Added thermal and acoustic insulation improves passenger environment.
Aesthetics & Branding: Allows seamless interior design with custom graphics or textures.

Applications

Train Car Interiors: Side walls in intercity, regional and commuter coaches; end walls between coach cabins.
Metro/Subway Cars: Interior walls of light rail and metro vehicles.
Special Dividers: Bulkheads or end-of-carriage partitions within multiple-unit trains.

Technical Specifications

Panel Thickness: Common total thickness 6–25 mm (depending on core).
Core & Skin: Aluminum honeycomb core with AA1100/3003 skins; sheet thickness typically 0.5–1.0 mm.
Surface Coating: PVDF or powder-coat finishes, anodized or mill finish as needed.
Size: Standard 1220×2440 mm sheets, custom sizes to 2200×12000 mm.
Fire Rating: Compliant with DIN 5510-2 (railway), NFPA 130 and other fire/smoke standards.
Environment: RoHS compliant; long service life (20+ years with minimal degradation).

Unique Selling Points (USPs)

Advanced Honeycomb Technology: Achieves Lightweight/High Strength/Fireproof/Anacoustic performance in one panel.
Design Flexibility: Endless finish options (colors, textures) and easy on-site modifications.
Ease of Installation: Large panels and honeycomb core allow bonding or fastener fixing; certified adhesive bonding up to Class A1 fire rating.
Sustainability: Panels reduce fuel consumption (lighter mass) and are made from recyclable materials.
