Panel Notes
With this panel engineering, you may opt to use heavier gauge coil and narrower width panels. Clip spacing will not change.
For slopes lower than a 2/12 roof pitch, contact SMI Technical Department for further installation requirements.
This panel uses a 24′′ coil (Steel) / 22′′ coil (Aluminum).
This panel uses 6-1/8′′ of material to form the panel.
If you take the square footage of the roof and multiply that by 1.34, the total will be the amount coil needed to manufacture the panels.
Clip Relief, Bead Ribs, Striations, and Pencil Ribs do not affect the engineering or function.
This panel is approved for Weathertight Warranties.
