Widebay Trussed Purlin Frame
WideBay Trussed Purlins, designed for bays up to 60' in width, can offer an economical and effective alternative to most traditional bar joist applications, and the results are stronger and more attractive.
The WideBay Trussed Purlin design can accommodate roof snow loads up to 40 pounds per square foot at a 5'-0” on-center spacing for a 60'-0” span. Adjusting the span and/or spacing can accommodate higher loads. And in spite of their brawn, WideBay purlins are better looking. UCC has designed a product that does more than its competition, plus has more aesthetic appeal. This new advance provides more flexibility, too. Depending on the application, top and bottom chords can be the same or different thickness. The vertical member placement allows for horizontal bridging and can be used to accommodate point loads. And unlike traditional bar joists, bridging can occur at a panel point or centered between panel points.
The WideBay Trussed Purlin is also flexible when it comes to roofing options. It is designed to work with VP's SSR roof system, or architectural metal roofs, or EPDM when using VP's Deck•Frame system.
