Instead of traditional membrane structure, our new patent carport is more popular. Traditional membrane structure installation is whole installation and it requires large hoisting equipment. If you just install one or two carports, the cost is high. To our carport, it just need 2 or 3 people to finish the installation in short time. During the installation, it does not need professional tool. Our carport do not to need Embedded parts. Our carport is very convenient for moving. We use 1050g/m2 . 0.8mm thickness PVDF membrane and it could stand 36m/s roughly 12 class typhoone. The PVDF roof  could be exposed outside at least 15 years ,no rust . The roof can be easily replaced.
