The national Speed Skating Stadium adopts the roof structure of super-large cable network, which is the first time for domestic high vanadium closed cable to be applied in the national key engineering project. Juli Rigging specially carried out technical research for this project, and broke through the core bottleneck in only 3 months, and hired an independent third-party inspection agency to verify the safety and reliability of domestic cable.

2022World Cup Main Stadium，Located in The city of Lusayr, Qatar, fixed seat 80,000. The stadium consists of concrete stands with a steel cable and membrane roof. Among them, the stadium roof adopts large span flexible cable membrane structure, juli rigging to undertake the whole stadium roof structural engineering.

National stadium (bird's nest), the largest span in the world of steel structure building, due to the advanced design concept, a lot of problems to the installation, roofing of ETFE membrane structure installation and maintenance is very dangerous in the future, therefore, juli rigging undertook the national stadium roof security cable system design and development work, optimize the security line system design, After testing, the technical performance of the product meets the engineering needs.
