Description

ACM Sheet, short for Aluminium Composite Material, is a lightweight yet strong composite panel made by bonding two thin layers of aluminium (0.13mm – 0.3mm thick) to a low-density polyethylene core. Known for its durability, rigidity, and versatility, ACM is widely used in construction, signage, and insulation applications. Its aluminium surface can be coated with PVDF or polyester paint, allowing for a wide range of colours, patterns, and finishes, including metallic, non-metallic, and even imitations of materials like wood or marble.

Benefits of ACM Sheet

  • Lightweight and Strong: Despite its lightweight nature, ACM offers exceptional strength and rigidity, making it easy to handle while maintaining structural integrity.
  • Weather Resistance: The aluminium layers provide excellent resistance to weathering, UV rays, and corrosion, making it ideal for outdoor use.
  • Aesthetic Versatility: ACM sheets can be coated in a variety of colours, patterns, and finishes, including metallic, wood, and marble effects, offering endless design possibilities.
  • Easy Fabrication: ACM sheets are easy to cut, shape, and install, making them suitable for custom projects and large-scale applications.

Applications

  • Signage: ACM is a popular choice for indoor and outdoor signage due to its lightweight, durability, and ability to hold vibrant colours and finishes.
  • Building Cladding: Its weather resistance and aesthetic appeal make ACM an excellent material for external cladding on buildings.
  • Insulation: ACM sheets are used in insulation applications, providing both thermal and acoustic benefits.
  • Interior Design: The versatility of ACM allows it to be used in interior design elements, such as wall panels, partitions, and decorative features.

Frequently Asked Questions​

What is Aluminium Composite Panel (ACP) used for?

Aluminium Composite Panel is a lightweight sheet material made from two aluminium skins bonded to a core. It is commonly used for signage, wall cladding, shopfitting, architectural features, and interior fit-outs. ACP is popular where a flat, rigid panel with a clean finish is required.

What is Aluminium Composite Panel made from?

ACP consists of two thin aluminium sheets bonded to a polyethylene or mineral-filled core. The aluminium faces are typically coated with a painted or anodised finish. Core type and coating vary by grade and determine suitability for signage, internal use, or external architectural applications.

What thicknesses and sheet sizes are available in ACP?

Aluminium Composite Panel is commonly supplied in thicknesses such as 3 mm and 4 mm. Standard sheet sizes are typically around 2440 × 1220 mm or 3050 × 1500 mm, depending on supplier. Custom cutting and sizing are usually available to suit specific project requirements.

Is Aluminium Composite Panel suitable for outdoor use?

Yes, ACP is widely used outdoors when the correct grade is selected. Panels with UV-stable coatings and appropriate cores are suitable for external signage and cladding. Not all ACP is exterior-rated, so material specifications should be checked before using it in exposed environments.

Is Aluminium Composite Panel fire rated?

Fire performance depends on the core material. Standard polyethylene core panels are generally not fire rated. Fire-retardant or mineral core ACP is available for applications requiring improved fire performance. Always confirm compliance with local building codes and project specifications before selection.

How durable is Aluminium Composite Panel?

ACP is durable, corrosion-resistant, and dimensionally stable. When used correctly, it performs well over many years, especially in signage and architectural applications. Longevity depends on coating quality, exposure conditions, and whether the panel is installed according to manufacturer guidelines.

Can Aluminium Composite Panel be custom cut or machined?

Yes, ACP is well suited to custom cutting, CNC routing, folding, and drilling. It is commonly supplied cut-to-size or fully fabricated for specific projects. Providing accurate drawings and tolerances helps ensure the panel meets fit, finish, and installation requirements.
