  • Based on CF-42 panel with 26 ga. exterior & interior face (min Fy = 33 ksi).
  • Based on attachment with U clip with (2) #12-24 SDS in min 14 ga. steel; or (2) #1/4-14 SDS in min 14 ga. steel; or (2) #1/4-14 STS in min 16 ga. steel. In lieu of self-drilling screws, self-tapping screws may be used.
  • Allowable positive load is the lowest value of panel bending strength, shear strength & deflection limit.
  • Allowable suction load is the lowest value of panel bending strength, shear strength, deflection limit and connection strength for each fastener pattern.
  • Connection* loads are based on side joint attachment only. Connection** loads are based on side joint attachment and additional expansion fasteners on the interior face of the panel.
  • The loads based on panel stress and deflection design criteria are derived from ASTM E-72 structural testing. The allowable loads are calculated with a factor of safety of 2.5 and 3.0 for bending and shear stresses, respectively, and deflection limitation of L/180.
  • The panel and its connection strength was determined from ASTM E1592 testing and the allowable loads are calculated with a factor of safety of 2.0.
  • The clip fastener capacity was determined from manufacturer fastener pullout data and the allowable loads are calculated with a factor of safety of 3.0.
  • The structural capacity of the support members are not considered and must be examined independently.
  • Consult Metl-Span for recommendations on panel profile and gage to resist thermal stresses.
  • For SI: 1 foot = 305 mm, 1 psf = 47.9 Pa, 1 inch = 25.4 mm.

  • Based on 26 gage minimum facings (min Fy = 33 ksi).
  • Based on attachment with CF panel clip with (2) 1/4"-14 Self-Drilling Tek 3 screws in min. 14 gage steel. In lieu of self-drilling screws, self-tapping screws may be used.
  • Allowable negative load is the lowest value of panel bending strength, shear strength, deflection limit and connection strength.
  • The loads based on panel stress and deflection design criteria are derived from ASTM E-72 structural testing. The allowable loads are calculated with a factor of safety of 2.5 and 3.0 for bending and shear stresses, respectively, and deflection limitation of L/180.
  • The panel and its connection strength was determined from ASTM E-72 testing and the allowable loads are calculated with a factor of safety of 2.5.
  • The structural capacity of the support members are not considered and must be examined independently.
  • Connection loads will increase with interior back fastening. Consult Metl-Span for loads and fastening patterns.
  • Allowable loads have not been increased by 1/3 for wind load design.
  • For SI: 1 foot = 305 mm, 1 psf = 47.9 Pa, 1 inch = 25.4 mm.
