Recommended for larger applications.
One of AIL’s latest innovations, extra-deep-corrugated Ultra•Cor Structural Steel Plate, is taking engineered Buried Metal Bridges to new dimensions in capability and performance.
Ready to handle extreme loads
With an impressive 500 mm (19.6″) pitch and 237 mm (9.5″) depth, Ultra•Cor’s ultra-deep corrugations allow it to reach greater spans and withstand the heaviest of loads. That strength also means accepting higher cover depths, and the mining industry is specifying it for haul road crossings and large tunnels. DOTs like it as an economical alternative to large bridges.
Ultra-deep corrugations to handle extreme surcharge loads
Ultra•Cor deep corrugated structural plate combines all the advantages of lightweight construction with previously unheard-of strength and durability to create the largest corrugated metal structures.
And, just like all AIL engineered solutions, Ultra•Cor ships and installs easily with minimal equipment and labour requirements.
Ultra•Cor is recommended for large bridges, tunnels, grade separations, road or rail underpasses, stream crossings, heavy haul road arches, stockpile tunnels, portals and canopies.
