Installing Standing-Seam Roofs On Pre-Fabricated, Pre-Engineered Steel Buildings
Tuesday, August 28th, 2007State-of -the-art standing seam roofs and their elements are favored over other categories of roofs offered today. The building industry standard that reigned as the through-fastened roof has been supplanted by standing-seam roofs. A seaming device field forms the elevated seams of the parallel standing-seam panels and provides for a finer roofing system contrary to those that are screwed down and fitted together. Sealing is generally applied at the production plant and located in the seam corrugation. Panels are secured to purlins with fasteners that allow some roof movement to support contraction and expansion.
