  1. Live/Press: Allowable loads applicable to downloads such as roof live, snow, and positive wind pressure.
  2. Allowable values are based on a 36″ wide panel with a 26 Ga. fascia and 26 Ga. liner with 3-1/4″-14 SDS in a 3′ wide panel at each supporting structural member.
  3. Connection for Walls: Screws located at the middle of the low pan centered between the high ribs of the fascia panel. Attach fascia sidelaps with 1/4″ Lapteks at 24″ o.c. max. spacing between main panel connections.
  4. Connection for Roof: Screws located at the middle of the high ribs of the fascia panel with an HW-355 bonded washer under the screw head. Attach fascia sidelaps with 1/4″ Lapteks at 18″ o.c. max. spacing between main panel connections.
  5. Pullout of the self-drilling screws from the supporting structural member must be checked separately.
  6. Allowable values have been derived from tests conducted in accordance with the ASTM E72 and ASTM E1592 test specifications.
  7. Allowable face buckling, shear, and panel pullover loads have been calculated using a 1.875 safety factor derived from test data scatter.
  8. Allowable values include a deflection check using a limit of Spacing/240 for Live/Press loading, and Spacing/240 based on 10-year wind pressures for Wind Suction loading.
  9. Allowable loads are given for equally-spaced supports.
