Helical Piles

We supply two distinct product lines. Our high capacity line allows the use of very high torsional capacities insuring maximum efficiency versus industry standards by incorporating a patented inertia welded machined connection. Our second product line, Large Diameter, is designed to mitigate higher lateral loads using by using larger diameter pipe with coupled connections.

High Capacity Helical Piles

From the 2-3/8″ workhorse to the 7″ Sherman tank, our partners utilize the very best seamless domestic oil grade (N80 grade) pipe and inertia weld 4140 alloy male and female ends to the tube. The 4140 alloy is machined by CNC precision machines, allowing for tight tolerances and optimal load transfers from section to section.

The most critical step is insuring the processes are never compromised by continually testing the finished product and our partners are one of the few suppliers that have availability to a testing facility patterned after the standards set by the ICC (A358).

If the property owner and/or the engineer of record demands superiority and assurance of the best, talk to us. With the assistance of trusted consulting engineers, and field support staff we will support and assist with your most demanding helical anchor or deep foundation requirements.

Large Diameter Helical Piles

Our large diameter helical piles and helical piers are used when projects require a deep foundation capable of resisting high lateral and/or excessive over-turn moment. Whether you have elevated pipe supports or cable trays on an oil & gas site, or if a transmission line is being built through a swamp, we can supply large diameter helical piles up to 60″ OD.
