A sports grandstand tension membrane is a type of architectural structure commonly used in sports facilities. It is made of a flexible membrane material that is tensioned over a supporting structure to create a durable and aesthetically pleasing covering. These membranes are known for their versatility, allowing for the creation of large, open areas with minimal support. They are often used in stadiums, arenas, and other sports venues to provide shelter, create a distinctive visual appeal, and enhance the overall experience for spectators.
