A door standing open on a loading bay is a hole in the building envelope. Conditioned air leaves, dust and insects arrive, and a forklift waits on the other side. High speed doors exist to shrink that interval, and their working parts explain where the money goes.
As the manufacturer rather than a reseller, we produce every variant ourselves and see which option survives a year of real traffic. One cycle tells you most of what matters. A trigger sends a signal, a servo motor accelerates the curtain, the guides hold it against wind pressure, and the bottom beam seals against the floor. Each of those stages carries a specification worth checking before you order.
Introduction to High-Speed Automated Door Systems
A roller shutter door built from 0.8 mm to 1.5 mm steel slat earns its place on a perimeter wall. It resists weather and prying, and the format scales to 12,000 mm wide. What it cannot do is cycle quickly, because the slat curtain is heavy and the operator has to keep acceleration low to protect the drive train. A door that needs half a minute to clear stops being a closure and becomes a bottleneck.
High speed doors take the opposite trade. The curtain is PVC-coated fabric or thin aluminium, the drum is small, and the motor is sized for repeated acceleration instead of raw lifting force. Raxdoor builds these units fr
