An Ultra-Cor highway overpass can span more than six lanes.
One of AIL’s latest innovations, Ultra-Cor Structural Steel Plate is taking engineered buried arch bridges to new dimensions in capability and performance.
Buried arch bridge spans of over 35 m (115′)
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.
Ultra-deep corrugations handle extreme loads
Ultra-Cor galvanized steel plate combines all the advantages of lightweight construction with previously unheard-of strength and durability to create the largest buried arch bridges, tunnels, box culverts and many other types of structures.
And, just like all AIL-engineered arch bridge solutions, Ultra-Cor ships and installs easily with minimal equipment and labour requirements.
Recommended bridge construction applications and more
Ultra-Cor is recommended for large bridges, tunnels, grade separations, road or rail overpasses, stream crossings, heavy haul road crossings, stockpile tunnels, portals and canopies.
Discover the many benefits of buried arch bridges
Structural plate bridges offer many advantages over concrete equivalents and traditional site-built beam bridges, truss bridges or concrete drainage pipes.
