Roof panels for the Sprinter Lighttrain in the Netherlands. For the Sprinter Lighttrain made by Bombardier, stainless steel sliding blocks were glued into the GRP profiles (A2 bonding) for high rigidity. Vertical tear resistance of 2,772 N was required for every single adhesive bond. This requirement was far surpassed in practice. The roof panel, which has the appearance of a 3dimensional component from a single cast, consists of pultruded GRP profiles and 3D moulded parts, partly combined with stainless steel components. 3Dprinted components may also be used.

Roof panels for the Flexity tram in Palermo, Italy What looks like a threedimensional, singlecast component on the sides of trams from the Flexity range from Bombardier, consists of pultruded GRP elements with gluedon end caps, which have been milled, glued, primed and painted. Optionally, the 656 mm wide roof panel can also be manufactured with a gluedon bracket. It has fire protection in accordance with NF F 16101 and DIN 5510. For new projects, we also meet fire protection requirements in accordance with EN 45545.

Produced similarly to the ISO-TECH system, MAXI-TECH is produced by using reinforced aluminum in the same wavy form to form the skeleton of the Panaspacer. It has polymer material used for thermal insulation and foil produced with triple lamination technology. Unlike the ISO-TECH system, it consists of making the aluminum surface stronger by covering it with an extra rubber material. MAXI-TECH has unique properties in terms of insulation and strength.
