To save installers money, we have engineered the use of locally sourced 2” or 3” schedule 40 steel pipe or mechanical 
tubing as the primary substructure element of our Ground Mount System. By allowing customers to source these 
materials locally, installers benet from reduced shipping, product and inventory costs, and shortened delivery times. 
We provide intuitive online tools that will help you quickly and easily craft a bill of materials to simplify substructure 
costing and purchasing.
When additional assistance is needed to address ground mounting your array, please contact our customer service 
team at 800-227-9523, or at support@ironridge.com. Many IronRidge customers prefer to use our online Design 
Assistant, found at www.ironridge.com/design.
A soils report is widely considered the most reliable and accurate method for determining the type and depth of 
piers for any Ground Mount System. Soils reports can be obtained through a Geotechnical Engineer. A commonly 
relied upon alternative to obtaining a site-specic soils report is to use the IBC 2006 Table 1804.2. The advantage of 
purchasing a site specic soils report is that the information provided often results in shorter embedment depths, thus 
lowering both material and installation cost.
In many cases installers rely on our easy to use PE stamped certication and post/pier installation guides that our 
engineering sta has made available for download. You will nd these and other IronRidge Ground Mount System

Schedule 40 Pipe
ASTM A53 Grade B standard weight (schedule 40) steel pipes or structural equivalent, with minimum geometry and 
material properties of:
•  3” pipe: OD 3.5”, wall thickness 0.216”, 35ksi yield strength
•  2” pipe: OD 2.38”, wall thickness 0.154”, 35ksi yield strength 
Mechanical Tubing
Steel mechanical tubing or structural equivalent, with minimum geometry and material properties of:
•  3” Tubing: OD 3.5”, wall thickness 0.165”, 45ksi yield strength
•  2” Tubing: OD 2.375”, wall thickness 0.109”, 50ksi yield strength
*Always check local building codes for pier mounting requirements specic to your location.
