ALISA overhead signs

What is ALISA?

ALISA is our Cradle to Cradle certified aluminum blue signage. This dew-resistant system, which is variable in both width (per mm) and height (per 150mm), offers an efficient and easy to install final solution for signposting on highways/roads. In addition, the ALISA system can be combined with displays and rotation lamellas.

Our ALISA overhead signs

ALISA overhead signs have proven themselves to be of true quality, practically, they meet very high quality standards. ALISA overhead signs can be attached to aluminium VICA portals, half-timbered portals and steel tube portals. The sizes of our ALISA products are flexible due to the use of aluminium strips in which the retroreflective foil comes all the way to the edges of the sign. Because of this, the overall picture looks very neat.
