Neckar bridge: A bridge of special features with Dillinger steel solutions

Setting sail with Dillinger LP plates

The elegant steel sails, which give the bridge its unique shape, are made of massive steel plates whose thickness increases steadily over the course of the tension chords to the mast heads. In order to be able to achieve this, Dillinger longitudinally profiled plates (LP plates) were used in thicknesses of up to 125 mm. For the highly stressed mast heads at the end of the steel sails, plate thicknesses of up to 200 mm (in the middle beam) were even required, which was realized using special Dillinger S460QL plates with toughness requirements significantly exceeding the standard. Thus, in this impressive project, high strength fine grained structural steel plates with such thicknesses were even used for the first time on a railway bridge in the DB AG network.

Another special feature for this bridge is the use of very heavy TM plates S460 ML > 30 t to reduce the construction site joints in the sails.
