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 Array System. By allowing customers to source these
materials locally, installers benet 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 [e-mail]. Many IronRidge customers prefer to use our online Design
Assistant, found at www.ironridge.com/gm.
A soils report is widely considered the most reliable and accurate method for determining the type and depth of piers
for any ground array system. Soils reports can be obtained through a Geotechnical Engineer. A commonly relied upon
alternative to obtaining a site-specic soils report is to use the IBC 2006 Table 1804.2. The advantage of purchasing
a site specic 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 certication and post/pier installation guides that our
engineering sta has made available for download. You will nd these and other IronRidge Ground Array System
documents located at ironridge.com/products/groundmounting/resources.
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 specic to your location.
