What Is A Pbr Panel

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.

RHINOs 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.

What Are The Pros And Cons Of Pbr Panels On Metal Buildings

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 todays steel buildings replace the old corrugated tin exteriors of yesteryear. Colorful, durable, and sturdy, todays steel panels perform far better and far longer than ever before.

Installing a metal roof over plywood roof is a common concern among homeowners because the plywood roof may not be strong enough to support the weight of the metal. In some cases, however, metal can be installed directly over plywood without the use of felt or a slip sheet. One of the first things to consider when installing metal over plywood is the weather. When the roof is subjected to strong winds or heavy rain, the metal may flex, causing structural damage to the structure. Furthermore, if the plywood is not properly installed, it may not be possible to attach the metal to the plywood, which may result in leaks and damage. It is critical to have a qualified contractor inspect the plywood before selecting a metal roof over it, as the plywood must be inspected for safety and used with the proper materials.

What Makes Pbr Steel Panels The Better Choice

Two basic types of steel panels dominate the metal building market today: PBR panels and R-panels. PBR panels deliver these strong advantages over R-panels:

  • RHINOs PBR panels are 26-gauge steel, while R-panels are formed with thinner 29-gauge steel.
  • The 1-1/4 rib height of a RHINO ribbed steel siding greatly increases strength over the shallow 5/8-deep rib of an R-panel.
  • A person walking on the roof will not crush the stronger PBR panel. However, weaker R-panels may crimp or buckle under a workers weight.
  • The deeper metal-to-metal contact of PBR panels increases waterproofing. The weaker connection of R-panels increases the likelihood of leaks especially in wind-driven rainstorms. Leaks penetrating the roof can soak insulation, causing a soggy mess.
