Metal building systems first gained popularity because of their reputation for being affordable and easily erected.
Helping provide longevity, sustainability, ease and cost effectiveness of metal building systems
While these advantages still ring true today, the emphasis on the up-front benefits of the system can sometimes overshadow the many long-term benefits, which include extreme durability and longevity, safety, energy efficiency, low maintenance and sustainability. The properties that give metal building systems such excellent performance are available to be built right into the system.
And PBR panels, or purlin bearing rib panels, are no exception—they’re commonly used for a wide variety of architectural, agricultural, commercial and industrial applications. PBR panels are incredibly durable, providing further proof that metal buildings are an investment that will last a lifetime, hold their value and continue performing at 100 percent.
Metal Building Applications
Considered one of the most economical panel systems available, PBR panels can be used for a variety of applications, such as roof, wall, liner, mansard and soffit panel applications. PBR panels are made of sheet steel roll formed in patterns engineered to increase its strength and resistance to impacts and wind loads. PBR panels have an extra lip, or purlin bearing leg, that not all panels have, providing a stronger connection for metal-to-metal contact, helping to create a greater waterproof barrier, limiting exposure to outside elements.
This is especially important in areas prone to wind-driven rainstorms. Leaks penetrating the roof or wall panels can soak insulation, causing an unwanted and unnecessary mess. A panel’s durability and longevity is directly related to how well it can be fastened and secured. PBR wall panels can be installed both horizontally and vertically, ensuring a functional design that meets all the necessary requirements for a building project. For use in roof panels, PBR panels fasten to the purlins. PBR wall panels attach directly to the wall girts. Standard coated, zinc-aluminum cast head or stainless steel head screws fasten the panels to the building with heads painted to match the roof or wall color.
PBR Pluses
PBR panels have 1 1/4-inch-deep ribs with exposed fasteners that deliver shape and dimension to building structures. Smaller ribs located between the deeper ribs provide panel reinforcement for added strength without adding weight to the panels. The panel configuration also enhances diaphragm capabilities for purlin stability. The ribbing on these panels also provides an even-shadowed appearance.
PBR panel Installation provides another advantage in that they can be installed over open framing or solid substrate. The minimum roof slope for PBR panels is 1/2:12, allowing structures more clearance for height restricted products. PBR panels also have a wind uplift rating and qualify for UL 90 in multiple construction numbers.
Available in various finish options including Galvalume Plus and the Signature 200 and 300 Colors, PBR panels also offer flexibility for integrating various and different types of building materials, as was the case for Cobalt Stables. This unique and creative facility in Olathe, Kan., integrated horse stables, training facilities and a human residence, all under one roof. Three buildings with an exterior skin of PBR metal panels attached to both wood framing and steel purlins, and allowed for the sleek aesthetic that was called for in the design.
As metal buildings continue to become more beautiful, eye-catching and attractive, the versatility and popularity of PBR panels continues to grow. Customers and builders are looking for quality products that provide not only longevity, but will also continue with the sustainability, ease and cost effectiveness of metal building systems.
