Lattice towers, also known as truss towers or angle steel towers, are freestanding steel framework structures widely used in telecommunications, broadcasting, and power transmission applications. Their self-supporting design provides the elevation required for antennas, transmission lines, wind energy equipment, and other infrastructure while maintaining structural stability under varying environmental conditions.
A typical lattice tower consists of a securely anchored base, load-bearing legs, diagonal bracing members that enhance rigidity, and a top section designed to support operational equipment. Towers are commonly fabricated using high-strength steel grades such as Q235B or Q345B and are generally available in heights ranging from 10 m to 100 m. Their open framework improves wind resistance by allowing airflow through the structure, reducing wind loading compared with solid towers. The design also distributes loads efficiently over a larger foundation area, making installation suitable for uneven or challenging terrain.
Key advantages of lattice towers include modular construction for easier transportation and installation, flexibility for future upgrades, the ability to support multiple equipment types, and lower material costs compared with monopole structures. Depending on application requirements, towers are commonly designed in square or triangular configurations.
The industry is closely linked to the steel sector. India has been the world's second-largest crude steel producer since CY 2018. Of the 1,878 MT of global crude steel production recorded in CY 2022, India accounted for approximately 125 MT, representing a 6.64% share. Between 2018 and 2022, India's crude steel production grew at a CAGR of 4.02%, outperforming the global average of 0.70%. Although global steel demand faced challenges due to the pandemic, inflation, and tightening monetary conditions, the World Steel Association projected global steel demand to grow by 1.95% to 1,822 MT in 2023.

A lattice tower is a self-supporting steel framework structure used to support elevated equipment. Its open truss design provides excellent strength, stability, and wind resistance, making it suitable for telecommunications, broadcasting, electrical transmission, and other industrial applications. The modular construction also simplifies transportation, installation, and future expansion.
High-strength structural steel is the standard material for lattice towers. Steel grades such as Q235B and Q345B are commonly selected because they provide a balance of strength, durability, and cost efficiency. Components are typically hot-dip galvanized to improve corrosion resistance and extend service life in demanding outdoor environments.
A lattice tower is a freestanding structure with its own load-bearing framework. Unlike a lattice mast, which depends on guy wires for stability, a lattice tower supports itself through its wider base and braced construction. Compared with monopoles, lattice towers generally provide greater load capacity and lower material costs for taller installations.
Lattice towers offer high structural efficiency with relatively low material usage. Their modular design enables convenient transportation, easier installation, future upgrades, and support for multiple types of equipment. The open framework also minimizes wind loading, making them suitable for demanding environmental conditions and uneven terrain.
Lattice towers are anchored using foundation systems selected according to site conditions. Drive stakes, wedge anchors, or other foundation methods may be used depending on soil or rock characteristics. Before shipment, manufacturers typically conduct quality inspections and structural testing and provide inspection reports and certification demonstrating compliance with applicable manufacturing standards.
The steel industry supplies the primary raw material required for lattice tower fabrication. Consistent availability of quality structural steel supports reliable manufacturing, cost management, and long-term product performance. Growth in steel production also strengthens the supply chain for infrastructure, telecommunications, and power transmission projects.
