Structural Components
1. Main Body: Vertical framework assembled from angle steel sections (e.g., 50x50x5 mm to 150x150x12 mm), connected via bolts or welding. Triangular or square lattice configurations enhance stability.
2. Cross Arms: Horizontal elements supporting antennas and transmission lines, adjustable in length and angle.
3. Platforms: Maintenance platforms with safety rails for technicians.
4. Lightning Protection: Rods and grounding systems to dissipate strikes, ensuring equipment safety.
5. Climbing Systems: Ladders, safety loops, and rest platforms for safe ascent.
Design Considerations
1. Load Capacity: Engineered to withstand wind (up to 200 km/h), ice loads, seismic activity, and equipment weight.
2. Height: Ranges 30–300 meters, determined by coverage needs and obstructions.
3. Modularity: Prefabricated sections for easy transport and assembly.
4. Compliance: Meets international standards (ANSI/TIA-222, IEC 60652, Eurocodes).

Angle steel tower refers to a self-standing tall steel structure made of angle steel. It is the earliest tower type used by operators. Angle steel towers are divided into two types: floor towers and roof towers. They generally consist of a foundation, tower feet, tower legs, tower body, platform, and lightning rod. , antenna bracket and ladder.
Angular steel towers offer economical, low-maintenance lattice tower structures that safely elevate critical communications equipment high above ground level.
Angle steel towers are large in size and occupy a large area. They are generally placed in suburbs or villages where land rent is not high. The amount of manufacturing and welding is small and easy to process.
Angle steel towers are suitable for counties, towns, fields, hills, mountainous areas and other areas with low landscape requirements and easy land acquisition. They are also suitable for areas with complex environments and difficult transportation.
The angle steel tower is assembled from angle steel materials and connected by bolts. It is very convenient to process, transport and install. It has high overall stiffness, strong load-bearing capacity and mature technology application. Angle steel towers are limited by the specifications of angle steel materials. The material utilization rate is low and the amount of steel is large. However, the unit price of angle steel materials is low. Overall, the cost performance has certain advantages.
The guyed wire tower has a novel appearance, reasonable stress, light weight, simple construction and short construction period. It is a communication tower with good performance, economical and practical, especially suitable for cities (urban areas) and scenic spots.
A guyed tower is a slender structure made up of truss members, which rests on the ocean floor and is held in place by a symmetric array of catenary guylines.
Angle steel towers are large in size and occupy a large area. They are generally placed in suburbs or villages where land rent is not high. The amount of manufacturing and welding is small and easy to process.
