Hormann industrial high speed or fast action doors are very popular where traffic is high but doors need to remain closed most of the time.
“These doors will open within a few seconds as pedestrian or forklifts approach, they can stay open for a few seconds and then quickly close when clear.”
The curtains are made from a PVC available in several different colours and normally include a vision panel.
If the unfortunate was to happen and the door was hit by a forklift it will self repair and be back up and running within a few minutes!
Hormann spiral doors are an external version of the above, instead of a PVC curtain the panels are solid giving insulation and security. Fully glazed doors are also possible
