A transmission line tower, also known as an electrical pylon, is a tall structure that supports an overhead power line. Typically, it is a steel lattice tower. Transmission towers in electrical grids carry high-voltage transmission lines that move bulk electric power from generating stations to electrical substations, where it is delivered to end users. Transmission towers fall into four categories: suspension towers,tension towers, dead-end terminal towers and transposition towers.

Our transmission towers can be made of angular steel, steel pipe or both. We design the towers to be high safety with high Material utilization so as yo control the cost. And the raw materials are from the trusted steel suppliers which we’ve been collaborating with for decades. In the stage of welding, CO₂ welding and submerged arc auto welding are adopted in our fabrication process. Both Factory test report and type test are available if required.
