Notes:

  1. Strength calculations based on the 2012 AISI Standard “North American Specification for the Design of Col-formed Steel Structural Members.”
  2. Allowable loads are applicable for uniform loading and spans without overhangs.
  3. Live Load/Deflection load capacities are for those loads that push the panel against its supports. The applicable limit states are flexure, shear, combined shear and flexure, web crippling at end and interior supports, and a deflection limit of L/180 under strength-level loads.
  4. Negative Wind Load capacities are for those loads that pull the panel away from its supports. The applicable limit states are flexure, shear, combined shear and flexure, and a deflection limit of L/60 under 10-year wind loading.
  5. Panel pullover and Screw pullout capacity must be checked separately using the screws employed for each particular application when utilizing this load chart.
  6. Effective yield strength has been determined in accordance with section A2.3.2 of the 2012 NAS specification.
  7. The use of any accessories other than those provided by the manufacturer may damage panels, void all warranties and will void all engineering data.
  8. This material is subject to change without notice. Please contact Metl-Span for most current data.

Notes:

*Fy is 80-ksi reduced to 60-ksi in accordance with the 2012 edition of the North American Specification For Design Of Cold-Formed Steel Structural Members-A2.3.2.

  1. All calculations for the properties of 7.2 Roof panels are calculated in accordance with the 2012 edition of the North American Specification For Design Of Cold-Formed Steel Structural Members.
  2. Ixe is for deflection determination.
  3. Sxe is for bending.
  4. Maxo is allowable bending moment.
  5. All values are for one foot of panel width.
