The Roof system consists of a cable structure with nine membrane elements made of PTFE-coated glass fiber fabric. The cable structure has rectangular membrane fields - seen from top view – which are tensioned by each high point. Following the axis grid of the grandstand structure, the high points of the cable structure are supported by four main masts by means of cables. These masts are placed at a distance of 18 meters each. The total length of the grandstand is 54 meters.
Cable structures by Ceno are one option to support membrane elements instead of structural steel.
