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

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

Notes:
- 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.
- Ixe is for deflection determination.
- Sxe is for bending.
- Maxo is allowable bending moment.
- All values are for one foot of panel width.
