CSP is 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.

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