Aluminum Composite Panel

Aluminum Composite Panel (ACP) is a sandwich-structured sheet consisting of two high-strength aluminum alloy face sheets bonded to a low-density polyethylene (LDPE) core or a fire-retardant mineral core through a high-temperature, high-pressure lamination process. The “aluminum skin – core – aluminum skin” structure combines the weather and corrosion resistance of aluminum with the lightweight and flatness characteristics of the core.

Product Description

Aluminum Composite Panel (ACP) is a sandwich-structured sheet consisting of two high-strength aluminum alloy face sheets bonded to a low-density polyethylene (LDPE) core or a fire-retardant mineral core through a high-temperature, high-pressure lamination process. The “aluminum skin – core – aluminum skin” structure combines the weather and corrosion resistance of aluminum with the lightweight and flatness characteristics of the core.

The typical structure consists of:

Face Sheets: Aluminum alloy (commonly 1100, 3003, etc.), thickness 0.12-0.50mm, chromated for enhanced adhesion

Coating: PVDF fluorocarbon (70% Kynar 500®) or polyester (PE) coating, providing color and weather protection

Core: Low-density polyethylene (LDPE) for standard type, or A2-grade mineral-filled core for fire-retardant type

Protective Film: Peel-off film to protect the surface during fabrication and installation

Aluminum Composite Panels combine lightweight, high strength, excellent flatness, easy workability, rich color options, and optional fire resistance, making them an ideal upgrade over traditional solid aluminum, stone, wood, and other building materials. Widely used in building facades, interior decoration, signage, transportation, and more.

Key Advantages & Features

01 Lightweight & High Strength

ACP weighs only about 60% of solid aluminum sheet (3mm panel approx. 3.5-5.5 kg/m²), yet provides sufficient wind load and impact resistance, significantly reducing building load and transport costs.
02 Excellent Flatness

The sandwich structure eliminates the “oil-canning” effect common in solid aluminum sheets. Panels are smooth and flat, ideal for large-area applications with superior visual effect.
03 Rich Color Options

Roll-coated with PVDF or PE for uniform, long-lasting color. Available in solid, metallic, brushed, wood grain, stone grain, and other finishes, meeting diverse architectural design styles.
04 Weather & Corrosion Resistant

PVDF fluorocarbon coating offers excellent resistance to UV radiation, acid rain, and salt spray. Service life exceeds 20 years—no fading, chalking, or peeling.
05 Optional Fire Ratings

Standard PE core achieves Class B2; fire-retardant PE core achieves Class B1; mineral-filled core achieves Class A2 non-combustible, meeting fire safety requirements for different building types.
06 Easy to Fabricate

Can be cut, drilled, routed, grooved, bent, and curved using standard woodworking tools. Ideal for complex shapes and custom designs with low fabrication cost.
07 Green & Eco-Friendly

Aluminum skins and PE core are recyclable. No formaldehyde, benzene, or other harmful emissions during production. Meets green building material standards.
08 Quick Installation

Flexible installation methods including riveting, screw fixing, dry-hanging, and adhesive mounting. Fast construction, effectively shortening project timelines.
