Custom 3mm Aluminum Sign – Durable Outdoor ACM Signage
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.
Popular Uses
Ideal for storefront signs, building signs, parking and traffic signs, construction notices, safety signs, directional signage, property signs, menu boards, informational panels, and branded displays.
