The installation process of the 4 legs angular steel tower should be carried out strictly in accordance with the design drawings and installation process to ensure the quality of installation. The vertical tilt of the center of the tower body shall not be greater than 1/1000 of the tower height, and the tower torsion angle shall not be greater than ±1 degree. Lightning protection measures should be considered for the tower body, and the protection range includes microwave antennas and communication rooms. A lightning rod should be installed on the top of the tower, and the room and the tower share a grounding system. As one of telecom tower types, the surface of the angle steel tower should be treated with anti-corrosion to increase its service life in harsh environments. Except for the foundation skeleton and the components buried in the concrete, all components are treated with hot-dip galvanizing for anti-corrosion, and the thickness of the galvanizing layer should meet the standard requirements.
