Old steel better than its reputation
In Germany, as in other countries of the western world, the infrastructure must be adapted to new requirements and safety conditions. This means that the renovation and repair of buildings places a considerable burden on the coffers of the state and companies.
Old steels are hastily regarded as unsuitable and dangerous to safety; however, intensive investigations and research by IWT-Solutions AG show that these attributions are not well-founded. In work on the Rhine bridges in Leverkusen and Duisburg Neuenkamp and on riveted weirs and bridges, IWT-Solutions AG has carried out targeted analyses of the properties of old steels.
It has been shown that old steels have a special property profile, which should be considered as a basis especially for repair by welding and for the assesment of brittle fracture resistance. From the basic feasibility in dealing with old steels, there is a wider scope of decision making for the building owners and economic and sustainable solutions are conceivable.
