Thanks to the sandwich design and lower thermal expansion, the material is dimensionally stable and therefore suitable for larger signs in the exterior and interior. The core is made of dark polyethylene. Both outer layers are aluminum. The edges are very clean and straight. After creating a V-groove or partial milling, it is possible to bend the board and thus create 3D boxes, etc. In this case, however, it is necessary to choose a board with a thicker aluminum layer. The surface is suitable for direct printing. It is washable and excellently weather resistant. There are also white-brushed variants, white-white, matt and glossy. It is also possible to order different colors. In the case where direct printing is not preferred, it is possible to stick the boards with self-adhesive foil or cut graphics. The material is available in many formats according to the specific manufacturer.

Printing

Direct UV printing, application of cut graphics, full-area gluing of foils

Warnings and recommendations

When using an aluminum sandwich board, the manufacturer's instructions for machining and installing the boards must be observed. Improperly selected material thickness or strength of aluminum sheet can complicate further processing or installation. For example, a poorly selected thickness of the aluminum layer (too thin a layer) can crack after partial milling and subsequent bending. Improper handling can cause the board to curl.
