NG series large steel structure counter current cooling tower adopts high-quality hot-dip galvanizing as the frame and glass steel sheet enclosure. The overall structure has been optimized. On the premise of meeting the requirements of user specifications, the beam-column section is small, which has an obvious effect on reducing the wind resistance in the tower and improving the cooling effect of the tower. In view of the fact that the fan is in the low-frequency vibration state in the operation process, adopting the glass steel plate with low vibration transmission can make the structure itself have good overall stiffness, which can effectively resist the influence of vibration in the operation process and the seismic action in the seismic area.
