Description
Aluminium composite panels (ACP) consist of two thin aluminium cover sheets bonded to a mineral-filled core. They offer high stiffness at low weight, good formability, and durable coil-coated finishes for facade cladding.
Typical Uses
- External wall cladding (with appropriate fire rating)
- Architectural façade systems
- Signage and display boards
- Interior wall linings
- Soffit and fascia applications
- Canopy and entrance features
- Column covers
- Partitions and false ceilings
