Hebei Chang Tong supply 4G Mobile single tube tower 4G communication angle steel tower 2019
Communication tower, the main structural form of four column angle steel structure, three column angle steel structure

[main function] it is mainly used for signal transmission.

[main purpose] it is used in China Mobile, China Unicom, China Telecom, China tower company and China Railway Communication Company.

[structure form] it is mainly 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. Lightning rod is set on the top of the tower, and the lightning protection grounding resistance is less than or equal to 10 ohm.

[technical parameters] wind speed resistance: 30m / s, ice coating resistance: 8mm, seismic intensity: 8 degrees, working temperature: 35-55 ℃, verticality: 1 / 1000.

[height dimension] 10m-50m.

[product features] round steel or angle steel is used as the tower material, with small wind load coefficient and strong wind resistance. The tower column is connected by outer flange or iron clad angle steel, and the bolt is tensioned, so it is not easy to damage, and the maintenance cost is reduced.

[service life] 30-50 years

[warranty period] 1-3 years
