  • Bridge in Biskupice

Combining PreCoBeam solution and weathering steel: a first in Europe!

In the village of Biskupice, Poland, ArcelorMittal Europe – Long Products and Steligence® contributed to the construction of a composite bridge built with ARCOROX® weathering steel hot-rolled sections, ensuring an external reinforcement for the concrete bridge. Inaugurated in March 2021, this is the first bridge in Europe built with the innovative PreCoBeam solution in combionation with weathering steel. Ensuring a maintenance free corrosion protection.

Arcorox® steel sections for better optimisation

For the external reinforcement of the composite superstructure, 15 tonnes of HE900B hot-rolled sections made of Arcorox® weathering steel in grade S460J2W+M were used. During the tender phase, the solution was part of the new design suggested by Steligence®'s engineers to guarantee optimisation of the tonnage (reduced by 30%), cost, and maintenance cost and to provide faster execution times. The sections were produced in ArcelorMittal Europe – Long Products' mill of Differdange, Luxembourg, and Steligence® Fabrication Centre supplied them to customer DURA through steel fabricator MOSTOSTAL Puławy S.A.

PreCoBeam technology

The bridge was built using the PreCoBeam technology and it was the first time in Europe it was used in conjunction with weathering steel. The HE900B sections are split into two T-sections, including clothoid-shaped composite dowels cut in the middle of the web. The T-sections are then used to create an external reinforcement of the steel-concrete superstructure. 

ArcelorMittal has been working closely with the customer all along the project, to develop both the steel grade and the technical solution.
