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.

Rail Underpass

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.

Mine Site Infrastructure

With achievable span widths of over 25m (82'), many of the world’s largest mine sites use innovative Super•Cor for its light weight, superior strength, versatility, ease of installation and environmental friendliness. Super•Cor is perfect for use in many types of largescale engineered structures, such as:

  • Heavy haul road arches
  • Rail underpasses
  • Portals
  • Stockpile tunnels
  • Escape tunnels

Affordable Bridge Replacement

Replacing aging bridges presents unique challenges to traffic management and infrastructure budgets alike. Progressive engineers and specifiers are turning to Super•Cor for its ease of installation and sheer economics. Super•Cor’s variety of shapes and profiles, along with its environmental friendliness, make it perfect for:

  • Short and Medium Span Bridges
  • Box Culverts
  • Vehicle and Railway Underpasses
  • Stream Enclosures/Crossings
  • Grade Separations

Animal-friendly Crossings

On today’s high-speed highways, motorists and wildlife can often find themselves on opposite sides of sudden and devastating encounters. The one thing they agree on, however, is that safety crossings made from Super•Cor provide low-cost, aesthetically pleasing and effective solutions for increased highway safety. Super•Cor is ideal for animal-friendly crossings like:

  • Highway overpasses and underpasses
  • Railway overpasses and underpasses
