In recent years, some with good performance have been developed into a new type of metal roofing materials, widely used in airports, railway stations, stadiums, convention centers, museums, cultural centers and other city landmarks, and gradually extended to the general construction. Metal roofing light weight, quick installation, good looks, popular with owners of all ages. However, a large gap to connect the metal roof, anchoring strength is low, it is vulnerable to wind damage, and sometimes even endanger people's lives and property. Therefore, the design of metal roofing systems, wind-exposed is a very important aspect, if the metal roof of the wind force to expose mainly the roof suddenly fell easily be damaged by strong winds. December 10, 2010, due to experience strong winds, Beijing Capital Airport T3, 200 square meters of the roof the wind lifted the metal plate, metal plate under the part of the insulation is blown run, resulting in hundreds of flights delayed. .....
Building roofing system security, including water, fire, wind exposed, anti-hail and anti-stampede, durability, etc., in which wind-exposed relationship to the building roof system is safe and reliable wind conditions, the safety of building a major impact, losses caused by damage is very serious. Therefore, whether domestic or foreign, the wind load on the building safety very seriously.
August 26, 2010, Suzhou, China Building Materials Academy's National Water Research Institute of Building Materials Industry Waterproof Building Materials Product Quality Supervision and Testing Center, introduced in the U.S. FM's FM approved roofing system testing techniques, including single volumes to carry out metal roof material roofing system and wind system, exposing the test business - China's first wind-resistant roof system built exposing laboratory.
New "polyvinylchloride (PVC) waterproof membrane," "thermoplastic polyolefin (TPO) waterproof membrane," "pressure-plate application of technical specifications" and other national standards have been proposed wind exposed roofing system requirements.
As more and more companies realize the importance of roof wind to expose the system and is to pay the price to the next roof system will be more secure.
