Panel Profile
What this panel actually looks like in cross-section — including how it's fastened.
High ribs on 12-inch centers carry the load, and exposed fasteners seat in the flat plane right beside the rib — never through the rib itself, the same fastening rule as our Tuff Rib Ag profile. At 1-1/4" high, the ribs provide the structural depth PBR is known for — purlins up to 48" on center on the roof, 72" on walls.
