ACM Signs: Affordable, Durable Signage with a Professional Finish

When you need a sign that’s tough enough to stand up to the elements—but still affordable enough to make sense for your budget—ACM signage (Aluminum Composite Material) is hard to beat. At Sun Sign Company, we’ve been using ACM for years to produce long-lasting, great-looking signs for all kinds of businesses, organizations, and events.

What Is ACM?

Aluminum Composite Material (ACM) consists of two thin sheets of aluminum bonded to a solid polyethylene core. It’s lightweight, rigid, and weather-resistant—ideal for indoor or outdoor signage. ACM comes in a large variety of sizes and thicknesses but these are our most popular and are the products we keep in inventory.

📏4' x 8' x 3mm – Standard-duty
📏4' x 8' x 6mm – Extra rigid for high-wind applications
📏5' x 10' x 3mm – Oversized for large-format signs

All panels are white and printable on both sides for double-sided visibility and design flexibility.

Why Choose ACM?

✅Weatherproof – No rusting, swelling, or warping
✅Lightweight yet rigid – Easier to install, strong enough to last
✅Smooth surface – Clean, professional finish for any design
✅Customizable – Can be cut to size and routed into shapes
✅Double-sided – Maximize visibility with a single panel
✅Versatile Decoration Options

– Full-color digital printing for eye-catching impact
– Premium cast vinyl lettering for ultra-long life and a classic look

Perfect for:

Business storefronts
Real estate and job site signs
Roadside signs and billboards
Church, school, and healthcare signage
Long-term exterior or interior displays

Durability Meets Value

If you’ve ever had a plywood or MDO sign rot, fade, or peel—you’ll immediately notice the difference ACM makes. It offers the look and strength of aluminum at a much more reasonable price. With proper care and decoration, ACM signs can easily last 7 to 10 years or more.

Fully Custom, Built to Order

We build every ACM sign to fit your exact needs. Whether you want a simple standard panel, a a more complex routed shape, or a two-sided display, we’ll help you select the best layout, size, and finish for your location and budget.
