R Panels (PBR)

Structural R Panels for Metal Roof & Siding Systems

The Purlin Bearing Rib (PBR) is a premium exposed-fastener panel built for residential, commercial, and agricultural roofs and siding. Its smart engineering includes a 5-degree over-bend and an underlap anti-siphon groove to form an impenetrable seal against severe wind and rain. From rustic interiors to durable exterior builds, PBR panels provide the strength, longevity, and clean finish your next project deserves.
