Custom 3mm Aluminum Signs for Indoor and Outdoor Use

Create long-lasting business, directional, parking, safety, real estate, property, and wayfinding signage with a custom 3mm aluminum composite sign. Each rigid ACM panel combines a smooth, bright white printable face with an aluminum back and a durable composite core. The matte finish helps reduce glare while keeping your custom artwork crisp and easy to read.

Why Choose a 3mm Aluminum Composite Sign?

• Outdoor-ready durability: rigid, waterproof construction suitable for demanding indoor and outdoor sign applications.
• Professional matte surface: reduces distracting glare and supports sharp, full-colour custom printing.
• Lightweight and rigid: easier to handle and install than solid metal while maintaining a clean, professional appearance.
• Custom finishing: choose square or rounded corners and optional 3/8-inch mounting holes to simplify installation.
• Made to your artwork: upload a print-ready design or request a proof before production.
