Product Name: Tubular Steel Lattice Transmission Towers
Tubular Steel Lattice Transmission Towers are self‑supporting lattice structures assembled from steel tubes and plate components. Different from conventional angle‑steel lattice towers, tubular‑member design brings higher overall rigidity and better wind‑resistance performance under heavy loads.
Featuring compact outline and outstanding structural stability, these towers are well‑suited for demanding project conditions. They are widely used for long‑span overhead power transmission, including river‑crossing overhead lines and coastal corridor projects.
All structural components go through hot‑dip galvanizing treatment for durable outdoor corrosion protection. Custom‑engineered to fit site‑specific conditions, they serve as reliable infrastructure for high‑voltage and ultra‑high‑voltage power transmission networks.
