The IronRidge® Ground Mount System combines our XR100® or XR1000® Rails with locally-sourced steel pipes or mechanical tubing, to create a cost-effective structure capable of handling any site or terrain challenge.
Installation is simple with only a few structural components and no drilling, welding, or heavy machinery required. In addition, the system works with a variety of foundation options, including concrete piers and ground screws. Compatible with soil classes 2-4.

Pipe and Tubing
Locally-sourced 2” or 3” schedule 40 pipe and mechanical tubing help you save on freight, while still spanning up to 18’ between vertical piers.
Schedule 40 Pipe
- 3” pipe: OD 3.5”, wall thickness 0.216”, 35ksi yield strength
- 2” pipe: OD 2.38”, wall thickness 0.154”, 35ksi yield strength
- 3” Tubing: OD 3.5”, wall thickness 0.165”, 45ksi yield strength
- 2” Tubing: OD 2.375”, wall thickness 0.109”, 50ksi yield strength
Hex-Head Set Screws
This custom component is required to connect the IronRidge Ground Mount foundation pipe to the ground screw. These hex-head set-screws provide corrosion protection and a thread-locking coating to ensure fasteners don’t loosen over time. IronRidge has designed and tested this set-screw for use with both Krinner Foundations’ and American Ground Screw’s solar products to meet the load requirements.
Ground screws perform well in a wide variety of soil types and conditions, from sandy and rocky to hard-packed clay. IronRidge completed compatibility testing with Krinner Foundations’ Solar Ground Screws (G-series), and American Ground Screws (Model 3) and now offers a certified systems engineering letter. Solar designers can acquire the letters on the Ground Mount Design Assistant platform.
