A hot dip-galvanised steel substructure has the stiffness that is required for such large structures. The casing is made from coated aluminium. The individual companies are created using high performance film. Removable panels ensure sufficient flexibility for the future. In order for individuals including external individuals to familiarise themselves with this large area quickly, a site plan with a guidance system was added. Banners have also been used to signpost each building once again. A complete system by LAUSCHNER®, from the analysis through to the planning and implementation.
