The traveler approaching the Bavarian capital of Munich from the north is greeted in the Schwabing district by a remarkably striking structure: two connected, slab-like high-rise towers, both with an outline in the form of a parallelogram. International star architect Helmut Jahn is responsible for the design of this unique project,
the "Münchner Tor", or "Munich Gate" office and hotel complex. Technically informed circles regard the support structure as a milestone in high-rise engineering; it consists entirely of a steel composite construction, the most important elements taking the form of supports with solid steel cores in concrete-lined steel tubes.

The heavy plate required for this challenging project was supplied
by Dillinger Hütte GTS. This material was used for fabrication of preassembled core-and-shell segments of two storeys in height, which then only needed to be concreted on site. The buildings are horizontally braced by means of floor elements and composite trusses which, for their part, also partially consist of Dillinger Hütte GTS heavy plate. A particular challenge was presented by the heavily loaded points of transition from the main supports to the reinforced-concrete underground structure, for which Dillinger Hütte GTS supplied foundation plates in the enormous thickness of 250 millimeters.
