UltraCor® is the world’s largest and strongest corrugated steel structure that earned a Guinness World Record for its wide span. Frequently used for bridges, tunnels, and grade separations, it combines the advantages of lightweight construction with enormous load-bearing capacity. UltraCor® is durable, eco-friendly and easy to install.
The width of over 30 metres is available for these structures. A bridge made of the UltraCor® steel plates earned a Guinness World Record for being the world’s largest metal buried bridge with a span of 32.39 metres.
UltraCor® structures are suitable for any class of live loads adapted for your needs. They can withstand the weight of people, cars, trucks, and railroads.
A bridge of 100×20 m can be assembled in just 3 weeks. The lightweight structures are assembled like a puzzle with a team of one trained supervisor and regular workers. The installation requires only one crane and some basic tools.
From the far north of Sweden to the scorching heat in Egypt, the structures can be installed both at -50°C and at +50°C.
The steel of UltraCor® structures is basically protected against corrosion by hot dip galvanizing. Depending on the environment (aggressiveness of water, air and backfill), we design accurate corrosion protection, including painting system if necessary. It ensures a long service life of 100-120 years.
Steel is 100% recyclable and uses several times fewer natural resources to be produced than concrete. The quick installation process ensures minimal pollution and environmental disturbance.
They have the deepest corrugation and thanks to this can be built as arch with span over 30m that is not possible by use of other corrugated steel structures”. UltraCor® is better solution then SuperCor or MP200, when we need to cross river, road or railway 30m or more wide, with just one arch.
