A fluorocarbon fiber membrane with strong corrosion resistance is used to cover the waste gas, and the steel structure is suspended outside. The corrosion resistance of fluorocarbon fiber membrane has been exerting and the corrosion problem of steel structure due to contact with corrosive gas has been fundamentally solved.

Because of the light weight and high tensile strength of membrane materials, membrane structures can fundamentally overcome the difficulties encountered by traditional structures in large span (intermediate unsupported) buildings, and are suitable for large span pools. Because all steel bracing anti hanging membrane structures are all sealed and the membrane structure is modeled as smooth surface (negative Gauss surface), the wind load shape coefficient is small and the wind resistant grade is high, so it can be designed according to the resistance to the 12 stage typhoon.
