robust aluminium tensioning-system to make XXL (PVC / banner) tension frames which can be mounted directly on to a wall (LED lit or unlit). The WR-Flex® system can be used to communicate (advertising) messages via large façades, or adorn or provide existing buildings with a “face-lift”. Simple mounting by pre-assembled, retractable corner fittings enabling straight cut profiles to be used. Thanks to the intelligent 'slide-in detail', the canvas (on the upper side featuring keder) can be slid smoothly into the tension frame. As such the wording on a message is always straight and large canvasses can be easily and quickly alternated. In addition to the mill finish version, WR Flex® is also available in a LED White Matt lacquer (RAL 9003) for even and bright illumination. In combination with the use of special light conducting, lightweight rear wall panels (LGP), optimal illumination can be achieved with fewer LED modules.
