  • Based on CF-24, CF-30 and CF-36 panel with 22 ga. Flat exterior face & 26 ga. Light Mesa interior face (min Fy=33 ksi).
  • Panel clips are fastened to min. 14 gage steel with (2) 1/4"-14 SDS Tek 3 at interior supports and (1) 1/4"-14 SDS Tek 3 at end supports.  For 12 gage or thicker steel, #12-24 SDS and 1/4"-14 SDS Tek 5 may be used.  In lieu of self-drilling screws, self-tapping screws may be used.
  • Allowable loads based on panel stress, connection strength and deflection design criteria are derived from ASTM E72 structural testing.
  • The allowable inward or outward loads is the smallest load calculated with a factor of safety of 2.5 for bending stress, 3.0 for shear stresses, 2.0 for connection and deflection limitation of L/180.
  • The structural capacity of the supports are not considered and must be examined independently.
  • Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.
