Aluminium Composite Panels for Cladding & Signage

Lightweight ACP sheets for repeatable flat applications

Aluminium composite panel, or ACP, uses thin aluminium skins bonded to a lightweight core. It is practical for repeatable flat sheets and routed-and-folded trays used in signs, shopfronts, interior walls and selected exterior cladding systems.

Best suited to: flat cladding, signs, commercial fronts, column covers and interior wall finishes.

Select as a system: total thickness, skin thickness, core, finish, joints, supports and fire requirements must be considered together.

Punchuk support: specification review, colour samples, sheet or tray coordination, quality checks, protective film, packing and export planning.

ACP Selection and Quotation Notes

Quick answer: ACP is a practical choice for lightweight, repeatable flat panels and sign or shopfront work. Use solid aluminium panels when the design needs deeper folds, welded details, perforation, tight curves or more demanding exposed-metal fabrication.

Selection and Design Coordination

Confirm sheet or cassette size, routing and folding details, joint pattern, support spacing, cut-outs, fixing method and thermal movement. For exterior use, coordinate wind loads, drainage, coating exposure and the complete installed assembly. Colour, gloss and grain direction should be approved from physical samples where appearance is critical.

Common Thickness, Skins and Core Options

Common overall thicknesses discussed for ACP are 3, 4 and 6 mm. Aluminium skins may range roughly from 0.15 to 0.50 mm across signage, interior and architectural grades. Core options may include polyethylene and mineral-filled constructions intended for improved fire performance. These products are not interchangeable. Final selection must follow the project specification, local code, exact tested assembly, required certificates, wind-load checks and fixing design. Do not infer fire compliance from an “FR” label alone.

Production, Inspection and Packing

After specification and sample confirmation, production may include coil or sheet inspection, lamination, cutting, routing, folding and tray preparation. Checks can cover overall and skin thickness, width, length, diagonals, surface condition, colour, protective film and agreed bond or peel tests. Sheets or fabricated trays are separated, protected and packed to reduce abrasion and edge damage during export.

Applications

Signage, wayfinding and display panels
Shopfronts and commercial facade renovation
Flat exterior cladding where the specified assembly permits
Interior walls, columns, ceilings and exhibition fit-outs

Aluminium Composite Panel FAQ

What is the difference between ACP and solid aluminium panels?

ACP combines thin aluminium skins with a lightweight core and is commonly used for repeatable flat cladding, signage and shopfronts. Solid aluminium is better suited to deeper forming, welding, perforation, tighter curves and heavier-duty custom details.

Does an FR core automatically make an ACP system code-compliant?

No. Compliance depends on the exact skins, core, thickness, joints, fixings, insulation and installed assembly, together with the test method and local code. Buyers should request documentation that matches the proposed product and system.

What information is needed for an ACP quotation?

Provide dimensions, quantity, overall and skin thicknesses, core and fire requirement, colour, coating, gloss, grain direction, flat-sheet or fabricated-tray scope, drawings, packing, destination and delivery schedule.
