You have probably heard the term “PBR steel panels”— but what does PBR mean? And what are the advantages and disadvantages of using PBR panels on a metal building?
Steel panels create the “skin” or exterior of most RHINO brand steel buildings. Panels cover both the roof and the walls of basic pre-engineered steel buildings.
The high-tensile-strength steel panels of today’s steel buildings replace the old corrugated tin exteriors of yesteryear. Colorful, durable, and sturdy, today’s steel panels perform far better and far longer than ever before.
“PBR” stands for “Purlin Bearing Rib” panels.
On a prefabricated metal building, steel components called “purlins” attach across the rafters. The PBR panels fasten to the purlins to create the roof of the structure. On the sides of the structure, PBR panels connect to the steel “girts” that run across the steel columns.
PBR panels are formed with deep trapezoid-shaped “ribs.” Smaller ribs fashioned between the deeper ribs provide added strength without adding weight to the panels. Consequently, PBR steel panels are very economical. In addition, the ribs increase visual appeal, creating even-spaced shadows over the structure.
High-quality rust-resistant screws with weather-resistant washers connect PBR steel panels on RHINO metal buildings.
RHINO’s PBR panels contain two layers of protective coating. The first layer is corrosive-resistant Galvalume®. The second layer is a baked-on color, available in a rainbow of vibrant colors, with a 30-warranty.
RHINO includes ribbed steel siding at no additional cost on a standard steel building order. (Other metal building companies often price their buildings with R-panels, offering PBR panels only at an “upgrade” price.)
RHINO offers optional 24-gauge standing seam steel roofing for those who prefer not to have screws penetrating the roof panels.
Energy-saving cool-coated panels, covered with a special light-reflective coating, save on utilities in warmer climates. Coastal areas, where salt spray permeates the air, require panels coated with a special Kynar® corrosive-resistant coating.
Keep in mind that steel panels are not the only exterior choice for prefab steel buildings. Adorn your RHINO steel building with ribbed steel siding, brick, stone, stucco, glass, Hardie® board, wood, or any other standard exterior building material.
