Framing System Package
Framing for the 40’ wide clear span building system is comprised of 2” x 4” 12 GA and 14 GA galvanized FLO-COAT steel tubing. There is no base rail used with this framing system. The truss member side post is plate mounted for attachment directly to a concrete foundation, footer or pier. A minimum 5” long x 5/8” diameter expansion bolt is required to anchor the plate on each leg. Sidewall heights available prior to any on-site fabrication are 10’, 12’, 14’, and 16’. Height extensions used in the erection of a 12’, 14’, or 16’ tall structure are fabricated using 12 GA 2” x 4” tube.
Truss Brace
The 40’ wide truss brace consists of a 2” x 2” 15 GA horizontal member with four (4) 1” x 1” 16 GA web members. These braces are required on all inside trusses to achieve the roof loads stated in the enclosed engineering summary. Included in the engineering results is the use of a knee brace (1” x 1” 16 GA). Depending on snow load requirement, not all situations will require the knee brace on this unit.
