An steel angle tower is a steel structure tower made primarily from steel angle, used mainly for communication, power transmission lines, broadcast television transmission, microwave relay, wind power generation, and other special purposes. The steel angle is named for its right-angle cross-section, and the tower has several advantages including ease of fabrication, sturdy structure, high strength, ease of assembly and maintenance, and relatively moderate cost. In the communication industry, steel angle towers are often used as support structures for base station antennas; in the field of power transmission, they are used to erect high-voltage power transmission lines, known as transmission towers; in wind energy utilization, steel angle towers serve as the foundational support structure for wind turbines. Overall, due to their excellent mechanical properties and broad applicability, steel angle towers play a crucial role in many engineering fields.
From the perspective of usage, steel angle towers primarily include communication towers, power transmission towers, broadcast television towers, radar towers, meteorological observation towers, and wind power towers. Among them, communication towers are mainly used for signal coverage of wireless communication network base stations, power transmission towers bear the task of supporting high-voltage power cables, and broadcast television towers are critical facilities for radio and television signal transmission. Structurally, steel angle towers can be further divided into self-supporting towers, guyed towers, monopole towers, cathead towers, four-leg towers, and single-tube towers. Self-supporting towers rely on their own structure's balance without external guy wires; guyed towers enhance stability through ground-anchored guy wires; monopole and single-tube towers use one or multiple steel tubes as the main structure, while cathead and four-leg towers are more complex, suitable for carrying heavier loads or for use in complex terrains.
As a crucial support structure in the power and communication industries, the upstream sectors of steel angle towers include steel materials, fasteners, and several other fields. Steel suppliers provide the primary raw materials for steel angle towers, with their quality and performance directly affecting the strength, stability, and durability of the towers; the supply of complementary products like fasteners ensures precision and safety during the assembly and installation processes. In downstream applications, steel angle towers are widely used in power, communication, and broadcast television fields. Power companies and power engineering construction companies are the main customers for steel angle towers, using them to support and protect transmission lines and substations; in the communication sector, steel angle towers play an essential role in supporting communication base stations and fiber optic cables; additionally, in the broadcast television industry, steel angle towers also play a key role in supporting broadcast television transmission towers and satellite receiving stations.
