A brand-new "SCO landmark", Qingdao·SCO Pearl International Expo Center, will be officially launched on 30 September 2022 according to the China-SCO Local Economic and Trade Cooperation Demonstration Area Administrative Committee. This is an important platform for Shandong Province and Qingdao City to promote the deep integration of capital, technology and talents between SCO and countries along the "Belt and Road" in a wider scope, broader field and deeper level. It is a landmark project of the the China-SCO Local Economic and Trade Cooperation Demonstration Area Administrative Committee, integrating exhibition, business, tourism and culture.
     Qingdao·SCO Pearl International Expo Center is located in the core area of the Local Economic and Trade Cooperation Demonstration Area, which has officially started its construction on 8 February 2022, overcoming various challenges such as the COVID-19 epidemic and taking less than eight months from the start of construction to the official opening, which has created a new "SCO speed" in the construction field. In addition, the construction is extremely complicated and the total amount of steel consumption in the venue is about 30,000 tons, with each component having its own characteristics. Most of them are spatial irregular shaped components, causing greater difficulties in processing, assembly and welding.
     The complex has adopted a large-span spatial hyperbolic tube truss structure with a form of fish-belly in inverted triangles, with a maximum span of 110m and a height of 8m, a roof with a width of about 220m, a depth of about 179m and a maximum height of 40m. The consumption of steel components amounts to 14,500t and the number of rods has exceeded 15,000 pieces.
