R-Panel vs. PBR Panels: What’s the difference?

R-Panel and PBR Panels look very similar, but have different applications- so what’s the difference? The difference lies in a small “leg” called a Purlin Bearing Ribs, or PBR.  This leg adds strength to PBR panels that enables the panel to be used in both siding and roofing applications.  R-Panels, on the other hand, do not feature this leg and are used only as siding.

Both R-panel and PBR panels are characterized by a distinctive “R” profile. referring to the shape of the metal panels, which typically have deep raised ribs or ridges that run vertically along the length of the panel. Panels feature 36” of coverage and a 1-1/4” rib height. These exposed-fastener systems are widely used in commercial, industrial, and agricultural buildings, but can also be found in some residential applications.

Key Features and Characteristics of R/PBR-Panels:

Profile Design: R/PBR Panels is known for their high-strength design, with the raised ribs providing additional rigidity and stability to the panels. The ribs are spaced at regular intervals, creating a pattern that contributes to the overall strength of the roofing and/or siding system.

Material Options: R/PBR-Panels are available 26 gauge steel, in the Sherwin-Williams® Weather XL™ finish. Although the R-Panel profile is available in all the JD Metals Weather XL™ colors. This coating ensures durability and resistance to weather elements, making R/PBR-Panels siding suitable for diverse environmental conditions. PBR-Panels, however, have a more limited palette, and we ask customers to call to see what colors are in stock.

Versatility: Both R-Panel siding and PBR roofing and siding panels are versatile and can be used for a wide range of applications. It is often chosen for commercial, industrial or agricultural buildings due to its ability to cover large siding spans efficiently. Residential homeowners who prefer an industrial look or who appreciate the strength and durability of R/PBR-Panels also choose this profile.

Ease of Installation: The exposed-fastener design makes installation relatively easy, which can contribute to cost savings in terms of labor and installation time. The panels are typically available in standard sizes, and their simple interlocking mechanism facilitates a straightforward installation process.

  1. Weather Resistance: R-panel siding is known for its weather-resistant properties. The raised ribs not only add strength but also help in channeling water, reducing the risk of leaks. This makes these panels a reliable choice in areas prone to heavy rainfall or other adverse weather conditions.
  2. Cost-Effective: Compared to some other siding materials, this profile is often considered cost-effective. Its durability, low maintenance requirements, and ease of installation contribute to its overall affordability.

As shown above, the R/PBR-Panel profiles are durable, versatile, and cost-effective options for specific applications.  What’s the difference? The “leg”, or Purlin Bearing Rib, which adds strength. So, remember: R-Panel= siding only, and PBR = roofing and siding. This distinctive profile makes it a popular choice for those seeking a reliable and efficient metal solution.
