• Customized non-standard lengths up to 18 m (60 ft) for diameters 3600 mm (144 in) and less, allowing less joints to be required.
• An economical solution in large diameters pipes, allowing savings in transport due to the optimization of the loading space.
  
• The pipe ends are adjusted to provide annular re-rolled corrugations, which allow couplings to be used to assemble successive lengths on a project.
• With their arched shape, they help minimize depth of the backfill while conveying additional water volume at a low rate.
• Withstands CL-625, H-25 and HS-25 loads.
• Lightweight compared to traditional materials.
• Bevelled cut in a driveway culvert application, increases the flow of water circulating in the culvert in the event of a thunderstorm.
  
• Optional spiral end, bevelled cut and arched pipes.
  
• The helical end, factory-welded steel eyelets, beveled cut, and curved pipes are also available upon request
