The PTFE membrane structure shed of Guiyang Cigarette Factory is the largest PTFE glass fiber membrane structure shed in the world at present. It is divided into two phases, north and south, and can park nearly 1000 cars at the same time. The steel structural parts of the shed are all cut and formed with precision instruments in Yexing Iron and Steel Processing Plant, and the error is less than 0.1cm. Due to the high processing accuracy of the steel structure, it provides a guarantee for the full coincidence of the membrane thermal joint and the steel structure, making the shed look more white, transparent and clean.
