In architecture, structural engineering or building, a purlin is a horizontal beam or bar used for structural support in buildings, most commonly in a roof. Purlins are supported either by rafters or the walls of the building. They are most used in metal buildings, though they sometimes replace closely spaced rafters in wood frame structures as well. Discount Metal Roofing offer a range of purlins and girts from 100mm to 400mm in Z and C profiles, cut to length, un-punched or punched to order or choose from our large range of pre cut purlins in our yard.
