Key Features
Rigidity-to-Weight Ratio:
Exceeds solid aluminum sheets of equivalent mass, lowering structural sub-frame dead load.
Surface Planarity:
Continuous hot-press lamination eliminates oil-canning across large spans.
Thermal Stability:
Exceeds solid aluminum sheets of equivalent mass, lowering structural sub-frame dead load.
Fabrication Compatibility:
Accepts standard CNC routing, V-grooving, cold bending, and mechanical cassette assembly.
Architectural Cladding: Exterior rainscreen facades, column enclosures, canopy soffits, and balcony spandrel panels.
Transportation: Interior linings and exterior skins for commercial trailers, refrigerated trucks, and railcar partitions.
Industrial Enclosures: Cleanroom partition walls, machine safety guards, and electronic equipment cabinets.
Signage: Large-format exterior advertising boards and architectural pylon substrates.
Surface & Finish Options
PVDF:
70% Kynar 500 resin system, >= 25 um DFT. Rated for 20-year exterior UV and weather resistance.
PE:
Single or double-coat application, >= 18 um DFT. Specified for interior architecture or temporary displays.
Anodized:
Electrochemical oxidation layer (10 um to 25 um) providing brushed or matte metallic textures.
Specialty:
Digital print receptive primers, wood grain transfer films, and stone texture coatings.
OEM & ODM Customization
Alloy Options:
AA5005 or AA3105 coils upon engineering request.
Dimensional Range:
