This profile type is manufactured in the winding process. The main properties of this profile is the smooth inside and, of course, the profiled outside. The low weight and the high stiffness are significant. The fields of applications for this kind of profiles are several pipeline systems, like for example sewer, drain, storm  drain and ventilation.



  • Smooth inner and outer surface for a good hydraulic, bright colour request.
  • Flexible and impact resistant.
  • Outside profile for high ring stiffness and good anchorage in the soil.
