4mm High Gloss PVDF Aluminum Composite Panel Weatherproof Facade Cladding for Curtain Wall

4mm High Gloss PVDF Aluminum Composite Panel – Weatherproof Cladding for Exterior Facades

Designed for architects, facade contractors and signage specialists, this 4mm high gloss aluminum composite panel pairs a mirror-smooth glossy surface with a 70% Kynar PVDF coating system. It is engineered as a complete exterior wall solution – strong enough for high-rise curtain walls, elegant enough for high-end commercial frontages, and stable enough to keep its finish for years outdoors.

Why This Panel Stands Out

• High Gloss Surface, 80–90 GU: A premium glossy finish with outstanding depth and color uniformity, giving facades and shopfronts a clean, reflective, architect-grade appearance.
• 70% PVDF Weatherproof Coating: Fluorocarbon coating resists UV, acid rain, salt spray and chalking, with color and gloss retention rated up to 20 years in exterior exposure.
• 4mm Engineered Sandwich Structure: Two aluminum skins bonded to a rigid core keep the panel flat, lightweight (~5.5 kg/m²) and impact resistant – far easier and cheaper to install than solid aluminum sheet.
• Fire Safety Options: Available with fire-retardant B1 core or non-combustible A2 mineral core to meet high-rise facade regulations.
• Excellent Flatness & Rigidity: High-precision continuous lamination delivers superb surface flatness and rigidity, avoiding the "oil-canning" that ruins premium facades.
• 100+ Colors & Finish Series: Standard RAL solid colors plus high gloss, mirror, brushed, wood, marble and metallic series to match any design intent.
• Easy Fabrication & Installation: Cuts, grooves, bends and folds with standard woodworking tools; compatible with cassette, rivet and curtain wall systems.

Applications

• Exterior building facades and curtain wall cladding
• Commercial / retail shopfronts and high-end elevations
• Billboards, signage and advertising panels
• Column wraps, canopies, eaves and gas station fascias
• Interior wall decoration, ceilings and partitions
