Television- and radio-transmitting towers are among the tallest and most fragile structures built, with some up to 2,000 ft (609.60 m) in height. Since the early 1930s, there have been hundreds of documented tower failures that have resulted in total or partial collapses. Losses can be due to wind loadings, ice formation, earthquakes, lightning, floods, collapses during erection, vandalism, and insulator and structural failures. Other losses can occur when aircrafts collide with them. Structural failures are most often related to poor maintenance or overloaded structures. Lives and property are at risk when a tower fails; the risk is greater in urban areas. In addition, there will also be loss of business income if the tower is unusable and transmission is interrupted for an extended period of time. It is important, therefore, to assure that towers are adequately designed, constructed, inspected, maintained, and equipped with the proper devices so that they function safely and efficiently. The towers considered in this report are open frame, trussed towers composed of metal members. They are used to support antennas for FM radio and television transmissions, as well as microwave dishes
Radio broadcasting TV Steel Towers is made up of the tower body, platform, the lightning rod, gym, antenna support structure, such as composition, and the hot dip galvanized anti-corrosion treatment, mainly used in the microwave, ultrashort wave, wireless network signal transmission and emission, etc.
