Self Supporting Tower
Self supporting tower usually is 3leg of 4leg tower, and its
material is steel pipe or angle steel. As for the connection,
tubular tower is connected by flange, and angle steel tower is
connected by nuts and bolts.
1.Small coefficient of wind load, strong wind resistance.
2.Save land resource, convenient location.

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
[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
