The phrase “PBR metal panels” has crossed your thoughts, but what does PBR mean? What benefits and drawbacks come with using PBR panels on a metal building? The majority of steel buildings bearing these are covered in steel panels. Essential pre-engineered steel buildings have paneled walls and roofs.
Today’s steel structures substitute the outdated corrugated tin exteriors with metal panels. Steel panels in use today are more vibrant, strong, and long-lasting than ever. Let’s know more about them!
What Are PBR Panels?
Panels with a “PBR” prefix stand for Purlin Bearing Rib.
Steel elements known as “purlins” fasten across the beams of a fabricated metal structure. The roof of the building is made with PBR panels attached to purlins. On the sidewalls of the superstructure, PBR panels link to the metal “girts” that extend across the steel girders.
PBR panels get made of “ribs” that are wide trapezoids. Shorter ribs created within the deep ribs give the panels more strength without adding weight. PBR steel panels are, therefore, relatively affordable. The ribs add to the structure’s aesthetic attractiveness by casting evenly distributed shadows.
Why Are PBR Steel Panels A Superior Option?
Currently, PBR panels and R-panels dominate the market for metal buildings. Compared to R-panels, PBR panels offer the following notable benefits:
- PBR panels are made of 26-gauge steel, whereas R-panels get made of 29-gauge steel, which is narrower.
- A corrugated metal siding’s 1-1/4″ rib length significantly boosts strength compared to an R-short panel’s 5/8″-deep rib.
- PBR steel panels get intended to overlap the most between panels than less expensive R-panels. Shorter overlap results in a significantly weaker link; longer overlap generates a stronger joining.
- The more durable PBR panel will not get crushed by someone walking on the roof. The weight of a worker, however, may cause weaker R-panels to pinch or buckle.
The more excellent metal-to-metal contact increases the permeability of PBR panels. Leaks are more likely to occur with R-panels due to their weaker connections, especially during wind-driven downpours. Insulation can become saturated by roof leaks, creating a wet mess.
Applications for Metal Buildings
PBR panels are one of the most affordable panel systems on the market. They can get utilized for several purposes, including roof, walls, and lining, mansard, and soffit panel applications. Sheet steel is roll-formed into PBR panels in designs that boost the material’s strength and resilience to impacts and wind loads. PBR panels, which differ from other panels in having an extra lip or purlin-bearing leg, offer a more powerful bond for metal-to-metal contact, enhancing the watertight seal and reducing exposure to the elements.
It is crucial in regions where wind-driven rainstorms are common. Insulation can get soaked by leaks that enter the roof or wall panels, creating an unwelcome and unneeded mess. The strength and lifetime of a meeting get closely tied to how effectively it can be fixed and maintained. PBR wall panels can be set up horizontally and vertically, guaranteeing a practical design that satisfies all building project needs.PBR metal panels are attached to the purlins to be used as roof panels. The wall girts are where PBR wall panels are attached. Standard coated, zinc-aluminum casting head or stainless steel head screws with tips covered to suit the roof or wall color secure the panels to the building.
