The Forum is an architectural gem in the heart of Groningen. On the top floor, dejor gratings have been used in the stairwell, façade and escape route. Some gratings are hinged so that the gratings can be placed in a vertical position. This flap function provides an opening for a concealed installation that can be lifted up for the purpose of façade and glass cleaning. Various types of gratings have been used including the Dejo carton grating (DPF) 30-2 33x33 and Dejo carton grating (DPF) 40-2 33x99. All gratings are galvanised and coated 2-layer in the colour RAL7048.
