The fast roll doors can offer an ideal solution to separate areas and departments, commercial and industrial buildings with wind resistance Class 3. They are made of metal, with a transverse at the top and aligned winding shaft side bearings. The metal structure is supported by vertical columns and with the beading guides, made from high molecular density polizene, self-lubricating and ideal for the sliding of the hinges.
The German origin polyester fabric coated with PVC, with strong resistance, weight 1300gr / m² and thickness 1,3mm, self-extinguishing Class 2 EN ISO 2060, made to withstand temperatures from +70 °C to – 10 °C. The PVC fabric is available in a variety of colors, including portholes at eye level of the average man, made of transparent crystal material with radiation protection in case a wireless sensor is positioned at the lower end. This new technology absolves us from internal horizontal metal bars.
The movement of the winding axis is via a three-phase motor 380 V – 50 Hz as standard IP 55 CE, with gearmotor and electrical brakes suitable for continuous use, 220 V power supply with inverter with multiple settings (such as the speed of opening and / or closing, the possibility of partial opening, the slowdown at the end of the route in the opening and / or closing, the time setting of automatic closing, etc.).
The settings are made via a handy microcomputer in a few seconds- and not manually and mechanically- with repeated testing, until the desired result.
The maximum opening speed is 2,5 m/sec (adjustable by choice).
The fast-roll doors are automatically repositionable drivers, so in case of a possible accidental collision, the fabric comes out from the side guides and when the winding starts, it reenters the drivers without any outside intervention.
