Solar Racks & Mounting Systems

Peirce Welding & Fabricating, Inc., located in Bethel, PA., fabricates solar racks & mounting systems engineered to International Building Code (IBC) 2006. Solar Racking Materials used are built to withstand the elements. General Steel grades used shall meet or exceed ASTM certification standards. All fasteners used are corrosion resistant and provide electrical continuity.

Solar Racks & Mounting Capabilities


Engineered to International Building Code (IBC) 2006, including associated American Institute of Steel Construction (AISC) that correspond to IBC 2006, and as a minimum meets or exceeds OSHA Category 1 construction criteria. Exposure class for each area/project will be applied in the final engineering document.

Racking Materials

  • Racking Materials used are durable enough to withstand the elements.
  • Material certifications for steel components utilized in fabricating the Racking system may be requested prior to accepting delivery.
  • Steel components will be supplied with coating ceertifications- for example: Hot Dipped Galvanized parts will have Certifications showing thay have been Galvanized to ASTM A123.
  • General Steel grades used for flat bars, angles, channels and plate sections shall be ASTM A-36 as a minimum.
  • Rectangular and square sections shall be ASTM A-500 grade B as a minium.
  • I-beam and H-beam sections shall be ASTM A-36 at a minimum.
  • Vertical supporting members for the Modules are ASTM A653 with a G90 coating Value

Fasteners & Hardware

  • Fasteners must provide corrosion resistance, as well as, electrical continuity.
  • Hardware to assemble the galvanized steel components will be A325 structural grade hardware that is Hot Dipped Galvanized.
  • Hardware to attach the Modules to the vertical supporting members will incorporate a stainless steel 18-8 serrated flange bolt, a stainless steel 410 external tooth lock washer and a stainless steel 18-8 nut to promote electrical continuity and a secure fit.
