Note: These are our most common shaft sizes, but we can custom manufacture helical piles up to 24” diameter with a .875 wall and up to 72” helix diameter to suit your specified material requirements and standards.
The capacities shown above for ultimate compression, tension and torsional strength values are determined by statistical analysis of laboratory testing results. A minimum factor of safety of 2.0 is recommended for determining allowable capacity from correlations with final installation. Load tests are recommended when practical.
