Features and Benefits

The widest span

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. 

High load capacity

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. 

Fast and simple installation

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.

Suitable for extreme temperatures

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. 

Long service life

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.

Eco-friendly

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.

    FAQ’s

    How are UltraCor® structures different from other ViaCon bridge solutions?

    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.

    Optimal solutions for railway bridges and road infrastructure

    In the realm of railway and road infrastructure, the selection of structural components is a critical factor that directly impacts the longevity, resilience, and safety of the construction. Among the many options available, structural steel plates, such as those used in the UltraCor® system, have emerged as a preferred choice due to their exceptional strength, durability, and versatility.

    Why structural steel plates are the preferred choice

    Structural steel plates, particularly those utilized in the UltraCor® system, are engineered to meet the rigorous demands of modern infrastructure projects. These plates are not only designed to withstand significant loads but are also tailored to perform under adverse environmental conditions. This makes them an ideal solution for constructing robust railway bridges, road bridges, and tunnel pipes that can endure the stresses of heavy traffic, extreme weather, and shifting environmental factors.

    Superior capacity

    One of the most notable features of UltraCor® is its outstanding capacity. The system is engineered to support the weight of heavy rail and road traffic, ensuring that bridges and tunnels constructed with UltraCor® can safely accommodate the demands of modern transportation. This robust capacity is crucial for maintaining the structural integrity of infrastructure, particularly in areas with high traffic volumes or where the infrastructure must support large, continuous loads.
    Expansive span capabilities for versatile applications
    UltraCor® is designed with expansive span capabilities, allowing for the construction of large, wide bridges and tunnels that meet the needs of diverse infrastructure projects. Whether used in railway overpasses, road bridges, or grade separations, the system’s ability to cover extensive spans without compromising on strength or stability is a significant advantage. This flexibility in design and application makes UltraCor® a versatile solution that can be adapted to various project specifications and site conditions.
