Guizhou Liupanshui―Baiguo Railway Beipan River Bridge is located between Liupanshui and Baiguo in Guizhou. The Company undertook the steel tube arch truss beam works, including fabrication of steel tube arches, surface corrosion protection, transport, site assembly, welding and coating. As the bridge site was away from major road and inconveniently located, site assembly was required. The unit part of main truss of steel tube arch should not exceed 8 metres in length, 2.5 metres in width and 10 tons in weight, so the construction was very difficult. It was awarded with “Lu Ban Prize” for architecture in China in 2005.
