A high-speed door is an automatic industrial door, usually with a PVC fabric curtain or rigid aluminum slats, that opens and closes much faster than a standard roller shutter. It is used at busy internal and external openings to cut traffic delays, limit air exchange, and keep out dust and insects. LESHO's range is listed at leshochina.com under High Speed Door.
LESHO lists PVC fabric high-speed doors (universal economy model), zipper-type self-repairing doors, stacking high-speed doors, aluminum alloy spiral high-speed doors, freezer high-speed doors for cold storage, and robot protection high-speed doors for automated cells. Product pages are on leshochina.com; sizes and options are confirmed per project.
Typical industry opening speeds are about 0.8–2.0 m/s for PVC fabric doors and up to roughly 2.5 m/s for spiral doors, with closing slower for safety. LESHO catalog speeds (open/close): universal economy PVC 2.0/1.0 m/s; zipper self-repairing 2.0/1.0 m/s; freezer high-speed 1.8/1.6 m/s; aluminum spiral about 2.0/1.0 m/s; stacking about 1.0/0.7 m/s; servo system max 2.5 m/s. Actual speed depends on door size, motor and control settings.
A zipper (self-repairing) door has curtain edges held in the side guides by a zipper-like strip. If a forklift hits the curtain, it pops out of the guides and re-inserts automatically on the next cycle, reducing downtime. A standard PVC door uses wind bars and usually needs manual reset after impact.
In Europe, power-operated industrial doors fall under EN 13241 (product standard), with safe-use requirements in EN 12453, wind load classification in EN 12424, and air permeability in EN 12426/12427. CE marking for the EU references EN 13241. LESHO catalogs list CE and ISO 9001 among certificates; current certificate files are available from sales on request.
Common safety features are photoelectric cells or a light curtain across the opening, a safety edge on the bottom bar, soft impact-resistant bottom beams, emergency manual or battery opening, and traffic-light signals. EN 12453 sets requirements for force limitation and presence detection on powered doors. LESHO standard safety kit: wireless soft bottom safety edge, photo sensor and warning lamp; optional radar, vehicle loop, remote and pull switch.
Yes, with a freezer-specific model. Freezer high-speed doors use insulated or double curtains, heated guides and seals to prevent icing, and low-temperature-rated motors and electronics. LESHO offers a freezer high-speed door with insulated double PVC curtain (about 30 mm), heated side rails and IP55 rating; confirm the minimum room temperature with LESHO for your project.
High-speed doors are built for frequent operation; typical industry designs target around 1,000 or more cycles per day and service lives commonly quoted in the hundreds of thousands to over one million cycles with maintenance. LESHO rates motors for more than 2,000 cycles/day; the zipper model is catalogued at 5,000,000 cycles tested, with typical service life 15 years (aluminum spiral 20 years).
