Export 60m Free Standing Galvanized Steel Iron Mobile Tower GSM/5G Station
4 Legs Self-Supporting Galvanized Angle Steel GSM Lattice Tower
4-legged Free Standing Steel GSM or 5G Mobile AntennaTower
Professional supplier and factory of Self-support free standing Galvanized steel Lattice Communication Tower, mobile phone 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.

Manufacturing Procedures of Telecom Steel Towers
1, Design layout and drawing, set up specifications and sizes.
2, Buy row angle steel plates and flat steel plates as well as galvanized steel bolts, nuts, washers and springs.
3, Measure and cut out sizes and holes.
4, Weld necessary parts (for angle steel towers, the welded parts are footing plates, antenna mounts, lightning rod, ladder etc.)
5, Polish burrs and welding scars to make all members good surface.
6, Assemble tower sections according to drawings, make sure sizes and connecting parts are correct.
7, Pretreament: clean surface corrosion and oil with acid or other chemicals-->clean with water-->dip in cosolvents-->dry-->dip in hot zinc pool for galvanization-->cooling and curing-->clean-->dry
8, Check quality and start packing.
