The electric iron tower produced by our company covers all specifications and models with hot-rolled angle steel. It was approved by the State Grid Expert Group in 2017 and became a qualified supplier of hot-rolled angle steel for the national grid electric power tower. The company also passed large-scale hot-rolling specifications. The corner steel manufacturer qualification certification has become one of the only two companies in China that can produce hot rolled angle steel for 28# and 30# UHV power towers. Our company is gradually developing hot-angle angle steel for weather-resistant series towers, which can enhance the service life of power towers in harsh environments and promote the development of power towers.
