Abstract:: Transmission pole and tower is one of the most important infrastructures in transmission line engineering projects.Hot-dip galvanising has long been the primary anti-corrosion solution for transmission pole and tower. However, the intermittent hot-dip galvanising industry has been identified as one of the industries that consume large amounts of raw materials and energy and produces numerous pollutants. In addition, transmission pole and tower with hot-dip galvanising corrosion protection need maintenance. Therefore, the development and application of novel anti-corrosion materials are important goals for power industries. In the atmos pheric environment, the surface of weathering steel will form a dense and stable rust layer with good adhesion,which has better corrosion resistance than ordinary carbon steel. The application of weathering steels in transmission pole and tower is an important development direction of corrosion protection. Using weathering steel to manufacture transmission pole and tower can solve the anticorrosion problem in the application process from raw materials, and the idea of “rust to prevent rust” can realize coating and maintenance free for its lifetime. The paper mainly introduces the applications and important research achievements of weathering steel for transmission pole and tower in China, including the composition design and performance research of the main raw materials (such as weathering steel plate, hot roll weathering angle steel and weathering steel bolts), corrosion behaviors of weathering steel in different regional climate, and the engineering application of weathering steel in transmission pole and tower.
