Speed Doors are door systems, mainly used in industrial applications. They are technical enhancements of the generally known sectional doors, PVC fabric doors or roller shutters. The main difference is that the durable construction provides a higher operating speed and they are able to sustain a higher number of cycles (opening and closing cycles) and require lower maintenance and repair cost. The speed can reach 4.0 m and beyond per second. Depending on the intended field of application, horizontal or vertical operating door types are available. They reduce to the maximum air currents and losses of ambient temperatures, and they make the intense flow of people and vehicles easier. In North America , the Door and Access Systems Manufacturing Association (DASMA) defines high-performance doors as non-residential, powered doors, characterized by rolling, folding, sliding or swinging action, that are either high-cycle (minimum 100 cycles/day) or high-speed (minimum 20 inches(508...
