Taking corrugated metal structures to new dimensions in capability and performance.
With the introduction of Ultra•Cor, Big R Bridge is taking structures like buried bridges to new dimensions in capability and performance.
Ultra-deep corrugations to handle extreme surcharge loads
Ultra•Cor combines all the advantages of lightweight construction with previously-unheard-of strength and durability to create some of the largest corrugated metal structures in the world today. With an impressive 20″ pitch and 9.5″ depth, its ultra large corrugations allow it to reach greater spans and withstand the heaviest of loads.
And, just like all Big R engineered solutions, Ultra•Cor ships and installs easily with minimal equipment and labor requirements.
Ultra•Cor is recommended for large bridges, tunnels, grade separations, road or rail underpasses, stream crossings, box culverts, heavy haul road arches, stockpile tunnels, portals and canopies.
