The project structure is a reticulated shell with a single-body projected area of 6500 square meters.

Lijiang Railway Station Project

Lijiang Railway Station's steel structure roof is 182.4 meters long and 50.3 meters wide, with a total weight of 1600 tons. From a high-altitude perspective, it resembles an airplane. The steel roof structure is complex, with numerous and diverse components, large spans, large individual weights, long cantilevers, and a steep slope. It has high technical requirements and demands high precision in manufacturing and installation. The main cross-sectional shapes of the box girders include rectangles, parallelograms, and trapezoids. The roof structure uses aluminum-magnesium-manganese plates.

Kunming International Convention and Exhibition Center Steel Structure Fabrication and Installation Project

Kunming International Convention and Exhibition Center exhibition hall, the columns are rolled steel pipes, the roof adopts a 70.8-meter span fish-belly type pipe truss structure, with a 2.6-meter cantilever on each side. Our company undertook the on-site fabrication and installation of trusses for exhibition halls 2, 4, and 6.
