Product Features
Electric High Tension Tower fabrication utilizes high-tensile Q345B steel to manage the heavy mechanical tension of long-span power lines while resisting wind pressures up to 50m/s. The lattice truss design offers a high strength-to-weight ratio, which allows for heights exceeding 60 meters with significantly lower foundation requirements than solid poles.
