Aluminum Composite Material (ACM) at Piedmont Plastics

Aluminum Composite Material (ACM) is a strong, lightweight, and durable panel made from two thin layers of pre-finished aluminum bonded on either side of a solid polyethylene (PE) core. This three-layer structure makes ACM panels a top choice for a wide range of indoor and outdoor uses. Known for their excellent dimensional stability, aluminum composite panels are used in everything from building signage and architectural cladding to POP displays, kiosks, and interior design features.

Because ACM panels are weather-resistant, easy to clean, and available in a variety of colors, finishes, and thicknesses, they’re a popular solution for projects that require both functionality and aesthetics. Whether you're working on a commercial renovation, a creative display, or an exterior facade, aluminum paneling offers the flexibility and strength needed to bring your vision to life.

At Piedmont Plastics, we supply high-quality aluminum composite material in multiple grades, including fire-resistant options, to suit your project needs.

Key Features of Aluminum Composite Material (ACM)

ACM has many advantages that make it a prime choice for indoor and outdoor applications, including:

Versatility: ACM panels can be easily cut, routed, fabricated, mounted, and installed using everyday tools.
Durability and Appearance: In addition to its eye-catching designs and durability, ACM remains flat over time, which reduces oil canning and rippling effects.
Light Weight and Cost-Effectiveness: Weighing approximately half as much as traditional aluminum, ACM panels offer a more cost-effective alternative to similarly gaged aluminum sheets.
UV and Weather Resistance: ACM provides excellent UV resistance, scratch resistance, weatherability, and an anti-corrosion skin, maintaining its sleek appearance over time.
Ease of Maintenance: ACM panels are easy to clean, preserving their brilliant finish.
Printability: Regarding signage and display applications, ACM readily accepts traditional inks, paints, digital printing, and PSA print media. Suitable for constructing type II electrical enclosures, it meets UL compliance (UL879) as a component for sign accessories.

Common Applications of ACM

The aesthetic qualities of ACM paired with its ability to be easily fabricated without sacrificing durability makes ACM an attractive material for various end user products. Some of these include:

Signage: ACM works well for sign-grade applications such as channel letters and POP displays due to its aesthetic appearance, light weight, and durability.
Specialty Vehicles: This material is excellent for exterior wall applications in trailers, emergency vehicles, food trucks, and RVs, reducing fuel and maintenance costs, improving aesthetics, and enhancing safety.
Building and Construction: ACM is excellent for applications like building facades, architectural cladding, insulation, and wall linings, offering long-term value due to its durability and low maintenance properties.

Frequently Asked Questions About ACM

Have questions about aluminum composite material? Our FAQs cover the essentials to help you make informed decisions.

Aluminum composite material (ACM) is a sandwich-like panel composed of two thin sheets of aluminum bonded to a polyethylene core. Lightweight, durable, and stable, ACM is ideal for both interior and exterior applications.

Yes, Aluminum Composite Material (ACM) is considered stronger than standard aluminum sheet in terms of overall performance, especially for signage and architectural cladding. It's stronger in terms of rigidity and form stability, has better impact resistance, and is lighter than solid aluminum.

Yes, ACM (Aluminum Composite Material) panels can be bent, but not like regular sheet metal. To create clean, precise bends, the panel is typically routed on the back side using a “V-grooving” technique. This allows the panel to be folded without damaging the outer aluminum layer. For curves, some ACM panels can be cold bent, but sharp angles require fabrication tools.
