Applications of Steel Towers
1, GSM, 2G/4G/5G cellular Mobile communications antennas mounting and telecom signal transmission tower.
2, FM, AM, VHF radio transmission tower.
3, TV station tower
4, Electrical power transmission and distribution pylon
5, Millitary watch tower
6, Radar Microwave tower etc.
Basic Procedures of Building A Telecom Tower
1, Site geologival investigation or survey to clasify terrain category and confirm it meets tower erection requirements
2, Design tower body and foundations
3, Test and specify the tower body and foundation by professional design and calculation software
4, Specify the tower and foundation dimensions and specifications of materials.
5, Prepare lofting and shop drawing of tower sections
6, Manufacture tower members according to the drawings and specifications.
7, Dig holes for the tower foundations and make a cement underlayer on the bottom
8, Make steel cage frames and anchorages for foundations
9, Make wooden molds for constructing concrete foundations
10, Set up grounding net with steel plates or rods around foundations.
11, Pour concrete and construct bottom blocks and pedestals
12, Dry and watering concrete foundations
13, Test the impact strength and make sure it meets the design specifications.
14, Fix tower footings to foundation pedestals and other tower members
15, Assemble tower sections and antenna brackets, ladder, rest and work platforms, lightning rod, grounding plates etc.
16, Set grouding of tower body and foundations, make sure at least 2 feet of tower must be connected with the ground net, lightning rod must be connected with grounding net through at least 2 foundations.
17, Test the straightness or verticality of tower
18, Complete if all specifications are confirmed.
