The double-layered folding doors are designed for areas where there is excessive wind force. It is a heavy industrial door that can resist a wind of 130 km/h.
Its main characteristic is the structure of its shears that can carry themselves in a vertical installation. The mechanism, without any kind of support, can carry its own weight. In case of a horizontal installation, the door is immobilized to another structure and works without any problem.
Its tarpaulin's structure and operating logic are the same with the boxtwinfold door. The characteristic that distinguishes them from each other is the structure of the shears.
