Properties Notes:

  1. All calculations for the properties of Rok-Bilt Steel ShadowRib panels are calculated in accordance with the 2001 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.

Allowable Uniform Loads 
In Pounds Per Square Foot – 16″ Panels

Allowable Uniform Loads Notes:

  1. Allowable loads are based on uniform span lengths.
  2. LIVE LOAD is limited by bending, shear, combined shear and bending and web crippling.
  3. NEGATIVE WIND LOAD has been increased by 33.333% and does not consider fastener pull-out or pull-over.
  4. Panel weight has not been deducted from the allowable loads.

The engineering data contained herein is for the expressed use of customers and design professionals. Along with this data, it is recommended that the design professional have a copy of the most current version of the North American Specification for the Design of Cold-Formed Steel Structural Members published by the American Iron and Steel Institute to facilitate design. This Specification contains the design criteria for cold-formed steel components. Along with the Specification, the designer should reference the most current building code applicable to the project jobsite in order to determine environmental loads. If fur ther information or guidance regarding cold-formed design practices is desired, please contact the manufacturer.
