Dillinger heavy plate for the
railway bridge “Kuhleshütte”

Advantageous and efficient: trough bridges with thick deck plates

Due to their many advantages, thick-plate trough bridges have been a tried-and-proven bridge type in Germany for many years. If bridges with small spans are required, this type of trough bridges is frequently selected in inner-city areas. The special benefit of this type of trough bridge is the fact that the deck plate consists of a single thick steel plate (or if necessary, several thick plates joint together in direction of train) with the advantage that it is possible to dispense with crossbeams underneath the track plate. Steel grades S275NL/ML or S355NL/ML in accordance with DIN EN 10025-3 and DIN EN 10025-4 are generally used for the deck plate (plate thickness ~ 100 mm).

Investment in the future

There is currently an increasing need to renew many existing bridges in Germany. The existing railway bridge “Kühleshütte” in Krefeld, which was built in 1913, had also reached the end of its technical useful life. Due to an upcoming widening of the road under the bridge, the trough bridge was extended from 8 m to 16 m. The prepatory measures began at the end of 2023. The railway bridge was completed and opened roughly one year later.

For the trough bridge “Kuhleshütte”, Dillinger delivered heavy plates of steel grade S275NL in plate thickness of 100 mm. A total of approximately 240 tonnes of our steel was used in this project.
