Galvanized steel Lattice Communication Tower, mobile phone Antenna
Tower, Radio Tower and TV tower, Power Transmission and
Distribution Tower
With more than 10 years in producing Self-supporting steel towers
which are the most popular suport systems for communication or
power transmission and distribution applications, we've been
exporting all kinds of steel towers and poles to dozens of
countries. The steel tower is 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.
