1. What is an Aluminum Sandwich Board?
An Aluminum Sandwich Board is a durable signage panel made from a 3mm aluminum composite material. It features two thin aluminum layers surrounding a polyethylene core, creating a lightweight yet rigid panel suitable for long-term indoor and outdoor signage.

2. What material is used to make this sign?
This product uses a 3mm aluminum composite panel consisting of two 0.15mm aluminum sheets bonded to a polyethylene core. This construction provides a strong, stable surface while remaining lighter than solid aluminum.

3. Can Aluminum Sandwich Boards be used outdoors?
Yes. Aluminum Sandwich Boards are designed for both indoor and outdoor signage. Their durable construction and UV-cured printed surface make them a suitable option for long-term displays. Actual lifespan may vary depending on weather, sunlight, installation, and maintenance.

4. Is the printing available on one or both sides?
Yes. You can choose between single-sided and double-sided printing, depending on how and where you plan to display the sign. Double-sided printing is useful when the sign needs to communicate information from both directions.

5. What is the UV Coated Dry Erase finish?
The UV Coated Dry Erase finish is a glossy, UV-cured coating applied over the printed surface. It helps protect the graphic while providing a surface that can be written on and updated using suitable dry-erase markers.

6. Can I write on the printed surface?
Yes. The glossy dry-erase coating allows you to write temporary notes, updates, or messages on the sign. For best results, use compatible dry-erase markers and test the marker on a small, inconspicuous area before applying it across the graphic.
