50m Free Standing Galvanized Iron Steel Mobile Tower 5G Antenna Station Mast
4 Legs Self-Supporting Galvanized Steel Lattice Tower
4-legged Free Standing Angular Mobile Antenna Mast
Professional supplier and factory of 4 legs Self-supporting Galvanized steel Lattice Communication Tower, Antenna Tower, Radio Tower and TV tower, Power Transmission and Distribution Tower
Self-supporting steel tower is the most popular tower for communication or power transmission and distribution applications. It’s generally designed as 3 legs or 4 legs and fixed on steel framed concrete pedestal foundations, composed of galvanized tubular steel tubes or angular steel plates by welding and fastening with bolts and nuts. With height of 20m to 120m, the galvanized iron steel lattice towers are widely used for mounting mobile communication macrocell or microcell stations and power transmission or distribution wires or cables.
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 120m. Besides using for telecommunications, the steel towers are also widely used for power transmission and distribution as well as TV and radio signal transmission stations.

60m High Mast 4-legged Galvanized Angle Steel VHF Antenna Towe Foundation Construction
The structure of 4-legged galvanized angle steel lattice communication tower is generally composed of steel framed concrete foundations, anchoring bolts, sections of tower body, 1 to 5 platforms, antenna mounting brackets, lightning protection rod, ladder, earthing plates, anti-fall safety system (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.
All the parts of tower are prefabricated in CKD (completel knocked down) steel members according shop drawings, ready for installation. When you install the tower, just fix the steel footings to concrete foundation pedestals by bolts and nuts and then connect the angular steel plate braces to the legs via welded connecting plates with bolts and nuts. In CKD way of fabrication, tower parts are easy for transportation and shipping cost is also much lower because you can ship more materials in a container or truck.
