Aluminium Composite for Signs

Aluminium composite brings a smooth, rigid face to a wide range of commercial signs. Choose from solid colours and selected metallic finishes for fascia panels, folded sign trays, letters and directional signage.

A guide to your options

A versatile material for panels, trays and cut lettering

Often called ACM or ACP, aluminium composite combines aluminium skins with a plastic core. It can be used flat, routed into letters and shapes, or formed into a tray with folded edges. This makes it a useful choice when several elements of a signage scheme need to share the same finish.

Materials & construction

The coloured sign-grade composite range uses board that is 3mm thick, with a 0.3mm aluminium skin on each side of an LDPE core. Other board grades differ, so the panel specification should be agreed for the finished sign rather than assumed from the name alone.

Aluminium Composite for Signs — material colour samples
Norgroup material samples. Screen colours are a guide; confirm your finish with a physical sample.

Choose the finish that fits

Flat panels

A smooth surface for applied lettering, vinyl or printed graphics.

Folded trays

A deeper fascia appearance with folded returns.

Cut letters

Flat lettering and logos, including selected metallic effects.

Plan the details

Sheet dimensions vary with the finish. Large panels and trays may need joints, and tray returns use part of the sheet allowance. Composite has a visible core at a cut edge; a brushed or mirror surface is a finish on composite, rather than solid stainless steel. Confirm colours using samples.

Your questions, answered

Is this solid aluminium?

No. Aluminium composite has aluminium outer skins bonded to a plastic core. Solid aluminium is a different material.

Can a large sign be made in one piece?

That depends on the selected sheet size, finished dimensions and any returns. We will plan joints where a single sheet is not sufficient.

Can graphics be applied to the panel?

Yes. The graphic specification can include suitable vinyl or printed graphics, agreed with the panel finish.
