Setting up Standing-Seam Roofs In Combination with Pre-Fabricated, Pre-Engineered Steel
Tuesday, November 21st, 2006Other categories of roofs offered today are, in large part, seen as a second choice to standing-seam roofs and their unique components. The through-fastened steel building roof that was favored as the steel building industry standard has been superceded by roofs made with standing-seam. Proper sealing is normally put on at the factory and placed in the seam furrow. A superior roofing application is obtained contrary to those that are lapped together and screwed down due to the fact that the high seams of the parallel standing-seam parts are field formed by a seaming apparatus. To adjust for expansion and contraction, roof panels are attached to purlins with hidden clips that permit some roof movement.
