Notes:

  1. The above loads were derived from uplift tests done in accordance with ASTM E-1592.
  2. Test results are highlighted.
  3. All values are interpolated from tests performed at spans of 3’-0”, 5’-0” and 7’-0”.
  4. Design Load contains a 1.75 factor of safety for 24 Ga. and a 1.73 factor of safety for 22 Ga.
  5. Stitch panels together at everysupport with (1) 1/4-14×7/8” Lap Tek.
  6. These values do not consider fastener pullout, clip attachment must be designed separately.
  7. This material is subject to change without notice.  Please contact Metl-Span for most current data.

Notes:

  1. Allowable loads are based on uniform span lengths and Fy = 50 ksi.
  2. Positive Wind Load is limited by bending, shear, combined shear & bending, and web crippling.
  3. Positive Wind Load is limited by maximum deflection rate of L/120.
  4. The weight of the panel has not been deducted from the allowable loads.
  5. The above loads are not for use when designing panels to resist wind uplift.
  6. Please contact manufacturer or manufacturer’s website for most current allowable negative wind loads.

Notes:

  1. All calculations for the properties of Designer Series panels are calculated in accordance with the 2007 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.
