Metal building products: Storm-proof

The Ziegelgraben bridge between Stralsund and the island of Ruegen is one of Germany's most remarkable bridge structures. From a 126 metres high pylon 32 diagonal cables branch off from stranded prestressing steel wire and carry the roadway. The material has to meet high demands due to the extremely rough winter storms in the region and the high traffic volume due to holiday and transit traffic. The sphere “Pre-stressing Steel and Prestressing/Clamping methods” of MPA NRW was substantially involved in the quality-assuring measures for the production of the stranded prestressing steel wires for the diagonal cables and their achoring components.
