Outdoor 5G Telecom Microwave Antenna Galvanized 4-Legged Angular Steel Tower
[main function] it is mainly used for base station signal transmission.
[main purpose] it is used in China Mobile, China Unicom, telecom, iron tower company and railway communication company.
[structural form] mainly steel pipe and angle steel structure.
[structure content] Q235B steel or Q345B steel or 20# steel is generally used, all of which are hot-dip galvanized for anti-corrosion treatment, and the connecting bolts are grade 6.8. The tower top is equipped with lightning rod, and the lightning protection grounding resistance is less than or equal to 10 ohms.
[technical parameters] wind speed resistance: 30m / s, ice wrapping resistance: 8mm, seismic intensity: 8 degrees, working temperature: 35-55 ℃, perpendicularity: 1 / 1000.
[height dimension] 10m-50m.
[product features] round steel or angle steel is used as the tower column material, with small wind load coefficient and strong wind resistance. The tower column is connected by external flange or angle steel clad iron, and the bolts are tensioned, which is not easy to be damaged and reduces the maintenance cost.
[service life] 50 years
