The central roof grid part of the building is supported by tree-shaped columns consisting of steel-pipes and cast-steel elements. 12 segments of 41 m width and 18 m length add up to a total length of 216 m. The frequent supports allow slender cross-sections and lead to a high transparency and lightness in the production hall.
In the side parts 18 × 18 m moduls of steel-grid are supported by tension-bars arranged along the grid-axis as well as diagonally.
