ETFE Membrane Structure For Chongqing Asian Cup Stadium

Chongqing Longxing Football Stadium is situated in the core area of Longsheng New Town within Liangjiang New Area, covering a land area of approximately 303 mu (equivalent to around 202,000 square meters) and boasting a total construction area of 166,900 square meters. It has a seating capacity of approximately 60,000 spectators with the completion of the first hoisting of a steel structure column weighing 4.5 tons. Completed in 2022, the stadium is a professional football venue constructed in accordance with the standards specified for the AFC Asian Cup.

ETFE materials exhibit a range of exceptional properties, including resistance to high and low temperatures, corrosion, aging, and water, as well as non-adhesiveness and self-lubrication. Furthermore, they possess excellent dielectric performance and a low coefficient of friction, rendering them widely applicable in industrial sectors and daily life scenarios—such as in the production of engineering plastics, coatings, and components for 5G base stations—earning them the reputation of "the king of plastics." Moreover, the aesthetic appeal of PTFE membranes is undeniable.

In the construction field, ETFE membranes are widely used in the roofs, walls, and daylighting systems of various buildings. Due to their excellent weather resistance and chemical corrosion resistance, they can effectively protect buildings from wind, rain, and chemical erosion. Meanwhile, Danka ETFE membranes also possess superior thermal insulation performance, which can effectively reduce the energy consumption of buildings.

As the first professional football stadium built in Chongqing and one of the largest professional football stadiums under construction in China, Chongqing Longxing Football Stadium served as a host venue for the 2023 AFC Asian Cup. Against the backdrop of the sustained growth of the sports economy and the increasing popularity of sports events, Chongqing is leveraging such events to promote the in-depth integration of "culture, sports, business, and tourism." With its open policy environment and inclusive urban culture, the city is continuously accelerating its pace of opening up to the outside world, thereby contributing to the upgrading of its urban brand.
