The PE core: light, rigid, easy to handle.
What sets a composite panel apart from a solid sheet is its core: a polyethylene (PE) layer bonded between two 5005 aluminum skins. For the professional buyer, that construction detail has real consequences on site — for transport, cutting and installation. This guide explains what the PE core changes.
Aluminum, PE,
aluminum.
The Ahlum ACP panel is a three-layer "sandwich": two 0.5 mm 5005 aluminum skins, one on each side of a polyethylene (PE) core. Total panel thickness is 4 mm.

Polyethylene (PE)
The PE core fills the inside of the panel and brings total thickness to 4 mm.
Matte PVDF
A matte PVDF coating covers the exposed face of the aluminum skins, in matte black or matte white.
What the PE core changes
for handling.
The polyethylene core isn't just a spec-sheet detail: it has a direct effect on how the panel gets transported, cut and installed.
Weight
A composite panel is noticeably lighter than a solid aluminum sheet of comparable rigidity — easier to handle with a crew on site.
Rigidity
The PE core gives a flat, rigid surface with no warping, even on a large 5×10 format.
Cutting and installing
The sandwich construction cuts and bends easily, for façade returns, corners and signage lettering.
4mm PE core:
your questions.
Why a polyethylene core instead of a solid sheet?
The PE core allows a 4 mm total thickness with two 0.5 mm 5005 aluminum skins — a panel that is lighter and more rigid than a solid aluminum sheet of comparable rigidity, without warping.
Does the panel bend easily for returns and corners?
Yes. The sandwich construction (aluminum / PE core / aluminum) cuts and bends easily, as summarized in the ACP panel spec sheet.
What does a 4×8 or 5×10 panel weigh?
The exact weight per panel isn't published on this page. For your load or handling calculations, request the full spec sheet through a quote request.
