Material Analysis of Power Steel Towers

The main structural material adopted for power angle steel transmission towers is hot-dip galvanized Q345 angle steel. This grade steel delivers much higher yield strength compared with common carbon steel, which perfectly fits the load-bearing demands of tower main legs, cross arms and primary supporting frames. After full hot galvanizing treatment, the metal surface gains reliable anti-rust and anti-corrosion performance to stand long-term exposure to wind, rain and ultraviolet radiation outdoors.

Auxiliary parts of the whole tower structure select hot-dip galvanized Q235 angle steel as matching accessories. These small secondary components include connection bracings, reinforcing strips and minor fixed supports that bear relatively low mechanical stress. Q235 galvanized angle steel balances stable performance and cost control well, meeting the basic structural fastening requirements without wasting high-strength Q345 raw materials on low-load positions.

M24 hot-dip galvanized high-strength bolts serve as the standard fastener set to connect all angle steel components tightly. These bolts lock main Q345 and auxiliary Q235 angle steel parts into an integrated tower framework, ensuring stable connection rigidity under strong wind and ice covering conditions. Standard M24 bolt specifications unify on-site assembly work, shorten construction time and keep the overall structural stability of power transmission towers for decades.
