Aluminum Composite Panels (ACM) — Lightweight Architecturally Versatile Composite Panels
What is ACM?
Aluminum Composite Material (ACM) consists of two thin aluminum sheets bonded to a solid polyethylene core, forming a lightweight yet rigid panel. Known for its exceptional flatness and durability, ACM is widely used in architectural facades, signage, wall cladding, partitions, and visual display elements. Available in multiple thicknesses—typically 3mm, 4mm, and 6mm—ACM panels provide the flexibility to meet a range of performance and aesthetic requirements across commercial and design-focused projects.
What materials and types define aluminium composite panels and metal cladding?
ACPs pair aluminum faces with cores of polyethylene, mineral-filled core, or fire-rated compositions to meet specific performance criteria. Metal cladding panels use materials such as aluminum, Galvalume-coated steel, copper, or zinc, with cores or insulation layers when thermal control is required. Variations include:
ACP with polyethylene core for lightweight façades
Fire-rated ACP for high-rise and public buildings
Solid aluminum panels for rainscreens
Steel panels with Galvalume coating for durability
These material choices affect weight, fire performance, rigidity, and installation methods.

How do metal cladding systems vary for architectural and commercial use?
Metal cladding systems differ by panel profile, joint type, and attachment method. Key categories include:
Standing seam panels with concealed fasteners for sleek rooflines
Interlocking wall panels that lock together for rainscreen assemblies
Exposed-fastener panels offering straightforward installation and cost efficiency
Insulated metal panels combining structural skin with rigid insulation
Each system balances aesthetics, thermal performance, and budget constraints to meet diverse architectural demands.
