Net-arch Bridges with Hot-rolled Sections
Net-arch Bridges with Hot-rolled Sections
ArcelorMittal – All Regions
- Composite bridges with hot-rolled sections represent an economic and sustainable solution for small and medium spans (10m ~ 45m). They can be realised in different innovative forms thanks to the flexible applications of hot-rolled sections.
- Composite bridges with hot-rolled sections in high strength steels are lightweight structures which are easy to handle on construction site and allow for an easy and quick erection.
- The short construction time makes composite bridges with hot-rolled sections the perfect and proven solution for rapid reconstruction after natural disasters, e.g. floodings, or wars.
Characteristics
- Achievement of light and aesthetic composite bridges by using hot-rolled sections in high strength steel (e.g. HISTAR® 460)
- Composite bridges with hot-rolled sections can be realized without any splices up to 40m in length.
- Steel composite girders with hot-rolled section can be easily placed by mobile cranes.
- High degree of prefabrication : Steel girders are finished in the workshop and delivered ready to erect.
- High quality of the solution is achieved by the high degree of prefabrication (e.g. welding in the workshop)
- Composite bridges with hot-rolled section in high strength weathering steel (Arcorox® ) allow for a reduction of the construction time and the maintenance costs over the lifecycle of the bridge.
- The carbon footprint of composite bridges can be substantially reduced by using hot-rolled sections produced from 100% recycled material and 100% renewable energy, as XCarb® recycled and renewably produced steel.
Applications
Refurbishment of the bridge “Pont de Pertus” , France (06), partially destroyed by floods in October 2020. Reopened in already 2021 using 4 girders with hot-rolled sections HL 1000 B in weathering steel (Arcorox® ) for destroyed span.
