A. Purlins and Girts: Purlins and girts shall be fabricated of cold-formed steel 8" or 10" deep, with LGSI shape.  Minimum thickness is 16 US gage; built-up sections are acceptable where required.  Purlins and girts shall be a "Z" or "C" shape.  Spacing and gage of these members shall be as determined by design and shown on the plans.  Purlins and girts shall be attatched to the primary framing members with 1/2" diameter A-307 bolts.

A. All frames, purlins, and girts shall receive one (1) shop coat of rust inhibitive primer after being thoroughly cleaned of loose mill and scale rust or other materials deleterious to paint bonding.

C. Cold Formed Steel: Steel used to form purlins and girts shall be hot rolled steel. Materials all conform to the chemistry requirements of ASTM A607 grade 50 or ASTM A570 grade.

A. Diaphragm strength of wall panel is used for wind bracing in endwalls, if sufficient wall panel is available. Where necessary, cable or rod bracing will be used to resist forces, sized to withstand required loading.

B. Galvanized Cable: meeting ASTM A475, sized to withstand required loading.

C. Adjustable Rod: meeting ASTM A36/A36M;ASTM A572/A572M Grade D; or ASTM A529/A529M, sized to withstand required loading.

D. Wind Columns: fabricated from shop welded, built-up steel plates, meeting ASTM A36/A36M, sized to withstand required loading, where seismic forces will allow.

E. Portal Frames: fabricated from shop welded, built-up steel plates, meeting ASTM A36/A36M, sized to withstand required loading.
