Purpose & Use

R-Panel/PBR-Panel is the Super-Duty® contender of metal roof and wall systems. Built with high tensile steel and well built trapezoidal ribs, there are few jobs too tough for this rugged panel.

Whether you choose R-Panel/PBR-Panel for its ability to handle slopes as low as 1:12 or open framing spans as far as 5′-7′ apart, R-Panel/PBR-Panel lives up to the demands you place on it.

R-Panel/PBR-Panel is most chosen for commercial and industrial roofs and walls, though it blends in well in most architectural design.

W.C. Esp - Andrew D. Patchogue, New York

Austen, I have spoken to our contractor, Mr. Andrew DiCorcia regarding the materials that we purchased from Best Buy Metals. Overall, he is very satisfied with the materials. The roof is complete and most of the siding is installed with the exception of some of the more tricky areas that required some cutting. The only issue they had was that some of the corners were the wrong side out but it wasn’t anything major that hindered the process. Thank you for following up with us and I appreciate all of your assistance and attention to this order. I have attached two photos and will send more along when the bldg. is complete!
