Hot-dip Galvanized Q235B, Q345B Steel Monopole Wind Turbine Tower, Monopole Steel Tower for Wind Turbine
Qingdao Powerup International Trade Co., Ltd is professional in supplying all kinds of Monopole Wind Turbine Tower, our factory has more than 10 years experience in manufacturing all kinds of steel towers and steel structure. Monopole Wind Turbine Tower is one of our main products. We have been making every effort to provide high quality Monopole Wind Turbine Tower. On one hand, auto-cad and prototype software are applied inprototype to ensure the precision of workshop drawings. A sample tower will be made for inspection before mass production. In mass production,we adopt advanced management to monitor the precise manufacturing progress of towers, to ensure each piece qualified. On the other hand, we equip our mechanical and chemical Labs with modern facilities, so that many routine experiments, such as Bearing Stress, Preece Test, Stripping Test and Five Elements Analysis etc, can be carried out smoothly, so as to ensure that our finish products meet with the ASTM or ISO standards.
