Question
What are aluminum sign panels?
Answer
Aluminum Sign Panels, also called aluminum sandwich board, are a rigid composite sign material printed with durable UV inks. The panel is built by bonding two thin aluminum sheets around a lightweight plastic core.
| Layer | Detail |
|---|---|
| Outer skins | Two 0.020" aluminum sheets |
| Core | Solid polyethylene center |
| Printing | UV inks for a durable, weather-friendly finish |
- The sandwich construction stays flat and rigid while remaining lightweight.
- UV-printed graphics resist fading, making these panels a solid pick for indoor and outdoor signage.
