Notes

  1. An asterisk (*) indicates allowable stress has been reached.
  2. A strikethrough (100) indicates less than 10 small PSF ASCE minimum.
  3. For structural roofing and siding made of formed metal sheets, a total load deflection shall not exceed L/60.
  4. Refer to Table 1604.3 limits and footnotes of the International Building Code (IBC) for additional guidance.
  5. Allowable spans and loads DO include self-weight of panel.
  6. All values are for one foot of panel width unless noted otherwise.
  1. Yield stress = Fy = 33,000 PSI.
  2. Loads and spans for carbon steel are based on AISI Standard for Design of Cold-Formed Steel Structure Members (2007 Edition).
  1. Yield stress = Fcy = 13,000 PSI.
  2. Loads and spans for aluminum are based on Aluminum Design Manual (January 2005).
