The R-Panel/PBR Panel is a superior roof or wall panel option. The profile design and rib height give this panel maximum strength allowing for it to be applied on roofs with very low slopes. Perfect for commercial & industrial projects, but can be used in residential & post frame applications as well. These panels are only available in 26 gauge and can be applied over open framing or solid decking. The primary difference between the R-Panel and PBR-Panel is the Purlin-Bearing Leg on the PBR-Panel. This leg provides better support for roof applications. The PBR-Panel is only available in Galvalume and Bone White. The R-Panel is designed for wall applications and available in all of our color options.
