 Super•Cor® - Box, Arch and Round structures

CSP Pacific are the sole distributor for Super•Cor® in New Zealand, manufactured by Atlantic Industries Limited (AIL).

Combining the advantages of lightweight construction with the superior strength and durability of galvanised steel, Super•Cor® is the most internationally accepted and widely used corrugation profile on the market.

The larger annular corrugations of Super•Cor® (381mm pitch and 140mm depth) provide nine times the stiffness of conventional structural plate.

Super•Cor® is the sensible economic choice for:

  • Vehicle underpasses
  • Bridges
  • Railway underpasses
  • Box culverts
  • Underground storage
  • Stream enclosures/crossings
  • Fauna underpasses
  • Mine portals


  Versatile - the corrugation profile allows for spans in excess of 25m
  Durable - properly designed structures with a heavy galvanised coating will last over 100 years
  Strong - the larger annular corrugations (381mm pitch and 140mm depth) provide nine times the stiffness of conventional structural plate
  Environmentally responsible - bottomless structures offer the least disturbance to the environment on installation
  Maintenance free - properly installed, the structures are relatively maintenance free
  Ease of handling - lightweight sections are economical to ship and easily handled
  Cost - low installation and maintenance costs over the life cycle of the structure makes Super•Cor® an economical choice
