ABSTRACT:
A roll-up door for opening and closing off door and gate openings. The roll-up door includes a hanging portion that is made of flexible material, is in a sheet-like form, and is guided along its sides in a frame. To increase the wind stability and strength of the hanging portion, profiled stabilizing members are securely connected to the hanging portion. The stabilizing members extend along the hanging portion at right angles to the direction of travel of the latter.
