Aluminum Sandwich Board — Rugged & Sleek Signage Solution

Upgrade your signage with aluminum sandwich boards—built for durability, weather resistance, and a professional finish. Each board is made with two sheets of corrosion-resistant aluminum permanently bonded to a polyethylene core, creating a lightweight yet rigid panel that’s perfect for both indoor and outdoor use.

At 1/8” (3 mm) thick, these panels are lighter than solid aluminum but strong enough to last for years. We print your graphics directly onto the surface using UV flatbed technology, then UV coat them for a gloss finish that’s waterproof, UV-safe, and scratch-resistant.

Whether you need single- or double-sided printing, these boards are a reliable choice for real estate signs, fence signage, wall-mounted displays, and more.
