3mm White Aluminium Composite 246

A white 3mm aluminium composite sheet engineered for strength, flatness, and weather resistance. The sandwich construction — aluminium faces over a polyethylene core — delivers an exceptional strength-to-weight ratio for large-format exterior and interior installations.

ACM panels offer excellent impact, corrosion, and weather resistance, making them particularly effective for outdoor installations exposed to the elements. The dual-sided gloss/matt finish provides versatility — use the gloss face for front-of-house applications and the matt face for secondary or internal surfaces. Stocked in a range of colours and achieves a minimum Class C fire rating.

Widely used for exterior wall cladding, fascias, shop signage, post-mounted signs, exhibition panels, POS displays, and printed graphics substrates. ACM can be machined, folded, and shaped to adapt to complex installations. The rigid, flat surface provides an ideal background for digital print, vinyl wrap, and painted finishes. Datasheets available upon request.

Physical Properties

• Construction: Polyethylene core bonded between two aluminium skins.
• Strength-to-weight: Exceptional rigidity at low weight — significantly easier to handle than solid aluminium.
• Flatness: Manufactured to tight tolerances for a smooth, professional surface.
• Finish: Dual-sided gloss/matt in white.

Durability

• Weather resistance: Corrosion-resistant, UV-stable, and dimensionally stable in outdoor conditions.
• Impact resistance: The aluminium skins provide dent resistance for exterior installations.
• Fire rating: Minimum Class C fire-rated. Datasheets available on request.

Workability

• Can be cut, folded, routed, drilled, and shaped with standard fabrication equipment. Accepts vinyl, print, and paint finishes.

Specification

• Material: Aluminium composite (ACM)
• Thickness: 3mm

Building & Construction

• Exterior cladding: Used for hotel and leisure complex cladding, mixed-use development exteriors, and entrance canopies. The white finish provides a modern, clean appearance that weathers well over time.
• Interior cladding: Column covers, lift surrounds, reception desk fascias, and feature wall panels in commercial interiors.

Signage & Graphics

• Post-mounted and fascia signage: The rigid, flat surface provides an ideal substrate for vinyl graphics, digital print, and painted lettering. Maintains dimensional stability in outdoor conditions.
• Shop signage and branding: Shopfront fascia panels, projecting signs, and branded entrance features.

Exhibition & Display

• Exhibition panel backdrops, POS displays, and hoarding graphics. The dual gloss/matt finish provides options for different visual requirements.

Fabrication

• Can be cut, folded, routed, and drilled with standard fabrication tools. The polyethylene core routes cleanly for folded box sections and cassette panel assemblies.
