Round Shaft Helical Pile & Extension

Round Shaft Helical Piles are high-strength deep foundation products engineered to support structural loads through weak or variable soil layers. Featuring precision-welded helical plates on a round steel shaft, these piles provide reliable compression and tension capacity with fast, low-impact installation. Ideal for residential, commercial, and industrial foundations, round shaft helical piles deliver exceptional load transfer and long-term performance across various soil conditions.


  • Shaft material: Seamless high tensile pipe, conforms to ASTM A500 Grade B/C or other customized meterial

  • Helical material: ASTM A36 Hot rolled plate

  • Corrosion protection conform to ASTM A123 standard for Hot-Dipped Galvanized coating

  • Leading edge of Helices beveled 45 degrees

  • Greater section modulus strength to resist twisting and deflection

  • Greater load capacities
