Roof tension membrane, also known as tensile membrane structure, is a type of architectural structure that uses a flexible, durable, and lightweight material, such as ETFE or PTFE film, to create a tensioned surface. The appearance of a roof tension membrane is characterized by its sleek, modern design and ability to span large areas without internal supports. This technology is commonly used in sports facilities, exhibition halls, and other public buildings for its aesthetic appeal and structural efficiency.
