ODM OEM Galvanized Tubular Steel Tower 20m 3 Legged Self Supporting
3 Legged Self-Supporting Galvanized Steel Lattice Tower For Mobile Communication Stations
We're professional manufacturer of steel towers and poles which are widely used for communications signal transmission and power transmission or disctribution. We've been specializing in fabrication of steel towers and poles for more than 10 years since 2009 and we can produce the towers and poles according to your designs, drawings, specifications and requirements.
SST: Self-supporting Steel Tower
Self-supporting steel tower is the most popular tower for communication or power transmission and distribution applications. It’s generally designed for 3 legs or 4 legs, composed of galvanized tubular steel pipes and angular steel plates by welding and fastening with bolts and nuts. With height of 30m to 100m, the steel lattice towers are widely used for mounting communication microcell or macrocell stations and power transmission or distribution wires and cables.

Construction of 3 legs lattice tower foundation
3 legged self-support steel lattice tower is generally made of tubular steel pipes as main structure (you can tell it as tower legs or body) and angular steel plates or pipes as sub-frame (horizontal and vertical bracings). The lattice tower is generally divided into several sections and the sections are connected by flange plates with bolts and nuts. Each tower section is made of tubular steel pipes and angular or flat steel plate, sometimes the tower is made of completely steel pipes or some bracings are made from solid steel bars.
3 leggs Galvanized Steel Lattice Tower with 2 platforms
The structure of 3 legged steel lattice communication tower is generally composed of foundation anchoring bolts (cage frames), sections of tower body, 1 to 5 platforms, mountning brackets, lightning arrest or protection rod, ladder, earthing plates, anti-fall safety system (external cage structure) and fasteners (such as clamps, clips, bolts and nuts etc.). The design, structure and height of telecommunication towers can be customized according to requirements and drawings.
Rooftop Steel Tower
5m to 15m Rooftop Bipod or Tripod or Lattice Tower
The rooftop steel tower is a small size tower for communication microcell station for enlarging the telecommunication signal coverage in the communities. It is typically designed as bipod or tripod tower mounted on the roof top, the height of rooftop towers is generally 5m to 15m. The rooftop tower is composed of a main pole which is made from tubular steel pipe and some angle steel or flat steel plates as bracings, connected by flanges, bolts and nuts. A foundation with anchoring bolts is also required for fixing the tower. Sometimes the rooftop tower is designed as wire guyed tower to make it with higher wind load.
