The car body structure, panels and axle steel of the 28 passenger cars used in Metro Line 1 in our city were all supplied by our company, of which the supply of stainless steel materials was close to 1,200 tons. The opening of this subway line has built a three-dimensional transportation network with seamless connection of "air-rail-rail transit", realizing seamless transfer between the railway station and the airport, marking that our city has officially entered a convenient and efficient "transfer era". This achievement not only demonstrates the important role of our company in the construction of public transportation infrastructure, but also provides citizens and tourists with a more convenient and comfortable travel experience.
