Prestressing steel pole saving than ordinary Poles, while partially prestressed pole is considered their respective advantages in the design, so that prestressing steel pole part in improving the situation with less increase in ordinary Poles 7m crack resistance of prestressed poles, thus ensuring the strength. But beware of partially prestressed and prestressed pole pole 7m their corrosion resistance of prestressed wire rod offer, durability worse than ordinary concrete poles. In daily life and production of prestressed wire rod suppliers 7m everywhere to erect wire poles, telephone poles that can be seen on the fine cross-section of the rod under the rough torus, and are designed to be hollow structure. Poles fine under thick, is variable cross-section rods. Meanwhile poles can be seen as a vertical axis of the cantilever. Under external loads 7m prestressed wire rod purchases, along the rod from top to bottom of each section of the growing moment, poles bottom suffered the greatest moment, so the poles is more susceptible to the upper end of the lower crude little moment. 7m prestressing wire rod purchases, Kyushu Electric Power Tower, 7m prestressing wire rods provided by Kyushu Electric Power Tower Henan limited liability company. Kyushu Electric Power Co., Ltd., Henan tower company (www.hnganta.com) in Henan, the other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
