Aluminum Sandwich Board

• Stays looking good outside — Every aluminum sandwich board comes with a UV topcoat that stops colors from fading even when the sign sits in direct sun for months on end.
• Light but solid — An aluminum sandwich board is easy to carry and install, but it doesn’t feel flimsy. The aluminum-and-core construction keeps it rigid without adding bulk or weight.
• Sharp, vibrant printing — UV printing goes straight onto the aluminum sandwich board surface, so graphics are crisp, detailed, and don’t peel or bubble over time.
• Scratch resistant — The protective coat on each aluminum sandwich board means everyday handling, transport, and outdoor exposure won’t easily damage the printed surface.
• Double sided option — Need visibility from both directions? A double-sided aluminum sandwich board has you covered for post-mounted or open-frame installations.
• Won’t rust — The face sheets on every aluminum sandwich board are corrosion resistant, so moisture, rain, and humidity won’t cause the edges to rust or break down.
• Professional finish — The gloss surface on an aluminum sandwich board looks clean and polished — it makes a real difference when the sign is representing your brand or a property listing.
• Fits standard sign systems — At 3mm thick, an aluminum sandwich board slots right into most real estate H-frames, T-posts, and standard riders without any modifications.

1. What is an aluminum sandwich board made of?

It consists of two thin aluminum sheets bonded to a polyethylene core. This composite construction provides a rigid, lightweight material for commercial signage.

2. Can these panels be used outdoors?

Yes. The panels are designed for indoor and outdoor use. Direct UV printing and a protective gloss coating help maintain the appearance of graphics in outdoor signage applications.

3. Is double-sided printing available?

Yes. You can select single-sided printing (4/0) or double-sided printing (4/4), depending on how your sign will be displayed.

4. What sizes and customization options are available?

Sizes range from 6″ × 6″ to 48″ × 96″. Multiple corner radius options and optional 0.25″ punched holes are available to suit different installation needs. Store pickup is required for sizes over 48″ × 38″.

5. How does this material compare with polystyrene signs and PVC outdoor signs?

Aluminum composite panels have a rigid structure with aluminum outer surfaces and are suitable for long-term signage. Polystyrene signs are plastic-based, while PVC outdoor signs use a different material construction. The best choice depends on your display requirements, installation method, and intended environment.
