The membrane structure car parking shed is a simple membrane structure facility. With the continuous growth of the number of cars and its own advantages, its demand is also increasing. Since it is a membrane structure building, what are the commonly used membrane materials for membrane structure car parking shed? Let SIGMA GROUP explain it to you!                                                                                                                                                                   

1. ETFE membrane material

Has excellent light transmittance, visible light transmittance is greater than 95%, long-term durability, long-term exposure to the environment, will not be degraded, and easy to recycle. The service life is usually more than 25-35 years.

2. PTFE membrane material

The membrane material is superior to PVC membrane material, and is different from PTFE membrane material in self-cleaning ability, anti-corrosion ability, and superior service life ability. It is not easy to age and has self-cleaning performance in rainwater.

3. PVDF membrane material

Compared with PTFE, the strength and fire resistance of PVDF membrane material have a certain gap, and the service life is generally 7 to 15 years. Membrane structure carport PVDF membrane material refers to a composite material formed by coating a PVC bottom layer on a polyester fiber woven base fabric, and then coating PVDF resin on the PVC bottom layer. This membrane material has been widely used in membrane structure buildings.
