PBR panel stands for purlin bearing R panel. This means that the panels have a larger overlap section that completely overlaps the next panel. This creates more metal to metal contact which yields a stronger connection and a more weather-tight metal roofing panel.
PBR metal panels are a low-maintenance, durable alternative to conventional roofing. The PBR panel profile adds extra protection against the elements by including a purlin bearing leg that overlaps between panels sealing out moisture and wind. These panels can be installed either on a solid substrate or open framing such as metal purlins or wood support beams.
