PVC Lifting Mega Door (2)

PVC fabric foldable lifting up door, can be made in huge size, to meet requirement of big size opening in aircraft hangars, shipyard, big machinery, and mining industry. The door is made from double layer PVC fabric curtain, and middle is strong steel tube framework to achieve excellent wind resistance.  The door curtain move up and down by folding up. It does not need big space at two sides to install such PVC fabric type hangar door or shipyard door. In some projects, such side space is very limited, so it is a good choice in such situation.
