       H꧅angxiao Steel Structure Co., Ltd. has rich experience in steel structure projects, and can provide project performance 𓆉services for large-span spatial structure buildings such as airports, railway stations, convention and exhibition centers, stadiums and gymnasiums. With the completion of a large number of large-span spatial structure projects with complex structural systems, large cantilevers, large spans and strange shapes, Hangxiao steel structure has become a large-scale municipal engineering steel structure manufacturing contractor.

The construction of large-span space steel structure is difficult and has high technical requirements, which can reflect the comprehensive ability of steel structure enterprises in design, manufacturing and constructiꦆon. Hangxiao steel structure actively carried out the research and development of long-span space steel structure technology, and formed a long-span space steel structure technology and construction method with independent intellectual property rights.

       These technologies have been successfully applied to the Guangzhou Asian Games complex gymnasium, Shenzhen North Railway Station of Guangzhou Shenzhen Hong Kong🎀 passenger dedicated line, Taiyuan Sou𝔉th Railway Station, Fujian Strait Convention and Exhibition Center, Chongqing Grand Theater, Hangzhou east railway station, Frankfurt air railway center in Germany, Doha International Airport in Qatar and other projects (add new large-scale key projects)

  Shenzhen North Station Hub Project of Guangzhou Shenzhen Hong Kong Passenger Dedicated Line

  
  

  The station building is a super long seamless structure, 345m long and 189m wide. The roof adopts a vertical and horizontal two-way truss system with "flat upper and curౠved lower". The maximum span is 86m and the maximum cantilever is 63m. The construction period is 6 months. It has won many honors, such as Luban Award, Zhan Tianyou award, China steel structure Gold Award, Guangdong Provincial Science and technology progress third prize, Guangdon𝓡g construction industry new technology application demonstration project, Guangdong Provincial Construction Project Quality Award, China Railway Science and technology second prize, China Railway Engineering Corporation first prize in science and technology and so on.
