Selecting RCS (Round Corner Square) Helical Pipes:

  • The helix(ices) size and number is based on the load requirement and insitu soil.  Contact the MacLeanCivil distributor for additional technical information.
  • The shaft size is selected based on the torque and load requirement.
  • When selecting the lead and extension length, consider the available equipment and location clearances.
  • Use only one extension with helix with a lead.
  • An extension with helix must only be assembled to a lead.
