Manufactured by Atlantic Industries Limited (AIL) from corrugated Steel Pipe (CSP), Super•Cor® is the culvert of choice for new or replacement culvert projects, reline projects and many other applications.

A high quality ​corrugated metal pipe​ that is built to last
It will not crack under impact loads or vibrations due to the inherent strength of steel and the flexibility of the corrugated pipe section. The high ring compression of the pipe absorbs and transfers the load to the surrounding soil around the entire circumference. The beam strength maintains the grade and line of the structure by bridging inequalities of the trench bottom and side fill.

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. View a time-lapse video of a twin Arch rail overpass construction.

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
