Super·Cor®
“Super·Cor®” (15" x 5.5" corrugation)
As Big R's revolutionary alternative to conventional bridges, Super•Cor represents our commitment to continued development in the field of corrugated metal structures.
Superior Strength. Lightweight Construction.
Super•Cor’s larger annular corrugations (381mm [15"] pitch and 140mm [5.5"] depth) provide nine times the stiffness of conventional structural plate. The lightweight, modular panels can be shipped easily and economically making it even more advantageous for remote locations.
Easy Installation
Simply put, Super•Cor saves time and money in installation. The panels require significantly fewer bolts than conventional structural plates and can be assembled adjacent to the job site, then moved into place using relatively light equipment. And, if the road needs to be widened later, Super•Cor allows for easy extension with additional panels.

Versatile
Super•Cor’s corrugation profile permits construction of the largest, longest and widest spans in a variety of configurations. Spans can exceed 25 m (82') with Big R’s proprietary features. Special shapes are also available, including Super•Cor reinforced box culverts in spans exceeding 15 m (50') with cover as shallow as 450 mm (18").
Durable
Super•Cor’s heavy galvanized coating is metallurgically-bonded to the steel surface, providing extended service life. Super•Cor is supplied with a standard 910 g/m2 (3 oz/ft2) coating. A heavier 1220 g/m2 (4 oz/ft2) coating is also available. Properly designed and installed, Super•Cor structures will last over 100 years.
Environmentally-responsible
Most Super•Cor structures used for stream crossings are bottomless. These structure types, combined with lower-impact installation methods, virtually eliminate deliberate streambed interference.
Maintenance-free
Unlike conventional bridges, which frequently require substantial retrofits, properly-installed Super•Cor structures are relatively maintenance-free.
Aesthetically-pleasing
Once installed, Super•Cor becomes a naturallyappealing structure. The geometry of the corrugations both softens and reduces the intrusiveness traditionally associated with man-made structures in natural environments.
