U-Panel vs R-Panel: Find Out the Differences!

U-Panel vs R-Panel: Find Out the Differences!

When erecting a metal building, there are many aspects that you need to take care of, and one such aspect is roofing. While installing a new roof, you do not only have to choose the type of metal for the roofing but also the kind of panel you want to go with. If you choose an exposed fastener panel, then you are left with the two metal roof panel types: R-panel and U-Panel. Choosing between these two panels could be tricky. But no worries, in this blog, Steel and Stud help you differentiate between U-panels and R-panels and choose the one which is most suitable for your metal building.

What is R-Panel Roofing?

R-Panel Roofing

R-panel has multiple uses. It can be used as a wall and roof in a pre-engineered metal building. Roofs made with R-Panels have raised ribs and extended flat areas between the ribs and are constructed of 36″ metal panels. It is great for both commercial and residential metal roofing purposes, and you can also use them as siding. It is primarily a prevalent option for residential metal roofing.

R-panel comes with Purlin-Bearing Ribs (PBR) and one without it.

Among many, one of the differences is that PBR Panels have a bigger overlap section which is not seen in R-Panels. This overlapping section between the panels, known as a purlin bearing leg, provides the metal roofing with more additional strength.

One of the similar characteristics is that these two-panel types have the exact coverage of 36 inches.

Depending on the location, usage, and other factors, your contractor will guide you on which panel to use.

What is The Thickness of The R-Panel?

In the United States, the unit of measurement used to express the metal roofing panels’ thickness is ‘gauge’. The higher the number of the gauge, the thinner it will be, and vice versa. The different gauges are 22, 24, 26, and 29. The thickest gauge is 22 gauge, and the thinnest gauge is 29 gauge. The most common is the 26-gauge R-Panel thickness people go with. It is typically more expensive to install metal roofing with thicker gauges. Many people believe using a thicker panel is always more beneficial, but it is not always true. The choice of panel gauge depends on the building’s structure and location

Different R-Panel Sizes: 

You can get R-Panel/PBR-Panel in custom sizes as per your specifications. The length available for R-Panel is between 3′ to 45′. Four 1.25-inch high ribs are spaced 12 inches apart in the centre of each R-Panel/PBR-Panel. It is easier to install stitch screws on roofs with PBR-Panel because it has a purlin-bearing rib. 

What is U-Panel Roofing?

U-Panel Roofing

U-Panels are exposed fastener metal roofing panels with a rib height of ¾” (approximately) and a rib spacing of 6″ in the center. It also provides a net coverage of 36″. It has applications in light commercial and industrial roofing and is most famous for its inexpensive exposed fastener design.

It is highly appropriate for interior partitions or liner panels for small storage facilities. You can choose among the various energy-efficient colors and paint systems available in the market. It is a stable, enduring, and sustainable metal panel that offers architects and owners of the building an impressive yet adaptable design when integrated with other building materials.

Furthermore, purlin bearing legs provide a consistent weather-resistant joint by accelerating installation and improving panel side laps. It also provides a lower profile and more delicate impression than R-Panel.

What is The Thickness of The U-Panel?

U-Panels, come in different thicknesses, which are 22-gauge, 24-gauge, and 26-gauge. The 22 and 24 gauges can be crimped curved to accommodate applications requiring radiused corners. 26-gauge U-Panel is great commercial-grade steel.

Difference Between R-Panels And U-Panels
