The fastest vertically opening industrial door — up to 4.0 m/s

The EFA-STR is the fastest vertically opening industrial door available: spiral technology accelerates the door leaf to opening speeds of up to 4.0 m/s. At that speed a doorway effectively stops being a bottleneck — traffic flows through with almost no waiting, and conditioned air stays where it belongs.

The door combines a spiral door-leaf support with a flexible curtain, running quietly and without wear because the leaf never touches itself in the spiral. It is built for intensive, round-the-clock logistics operation.
