35m 3 Leg Tubular Telecom Steel Tower Q345 For Macrocell Antennas
35m 3-leg Tubular and Angular Steel Communication Tower for Macrocell Antennas
Galvanized steel Lattice Communication Tower
There are 3 popular types of lattice communication towers--ground fixed self-spoorting steel towers, rooftop self-supporting steel towers and steel wire guyed towers. The steel lattice towers are usually as high as 35m to 100m.

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 35m to 100m, the steel lattice towers are widely used for mounting communication macrocell stations and power transmission or distribution wires or cables.
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.
The sections of tubular steel lattice tower completely made from steel pipes are generally welded in factory by 5m or longer lattice parts, each section is welded with flange plates for connection among tower sections. When you install the tower, you need to construct foundations with anchoring bolts frame (someone calls it steel cage frame) and concrete. The tower is fixed to foundations via flange plates with bolts and nuts. This kind of tubular steel lattice tower is easier for installation and very solid and strong, but the cost is a little higher and more costly for transportation because all the tower sections are welded in big parts which take more room in the truck or container.
So the most popular 3 legged steel lattice tower is made from tubular pipes and angular steel plates. The steel pipes are made for tower legs, angular steel plates are made for bracings (support members) and flate steel plates for connectors. The steel pipes are welded with flanges at each end for connection. All the parts of tower are prefabricated in CKD (completel knocked down) steel members ready for installation. When you install the tower, just fix the steel pipes to foundations by bolts and nuts and then connect the angular steel plate bracings to the pipes via welded connecting plates with bolts and nuts. In CKD way of fabrication, the cost is lower and shipping cost is also much lower because you can ship more materials in a container or truck.
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.
