Zhang La Membrane Ceiling Works refer to architectural structures featuring a tensile membrane roof. These roofs are made from flexible materials like ETFE (Ethylene Tetrafluoroethylene) or PTFE (Polytetrafluoroethylene), which are tensioned over a supporting structure. They are known for their innovative design, durability, and ability to create large, open spaces without internal support columns. Membrane roofs are often used in sports facilities, exhibition centers, and other large public buildings.
