High speed spiral door, also known as aluminum alloy fast door, or hard shutter for short, is a new type of metal fast door that is anti-theft, wind-resistant, and high-temperature partition. It is reliable, practical, and easy to operate.

1. Infrared safety photoelectric, there are radio eyes on both sides of the door frame. If there is an object below the fast door, the door will remain open; when the door body is lowered and there is an object passing below, the door body will open to the most open position until there are no obstacles below. time and then delay the descent.

2. Safety bottom edge. When the door body is descending, because the object is in the blind zone of infrared safety protection, when the door body presses on the obstacle below, the door body quickly rebounds to the most open position, effectively protecting the objects or pedestrians below. Avoid accidents.

3. The light curtain protection system installs a grating wall in the direction of the vertical position. It calculates the position of the curtain based on the actual height of the curtain body and provides an effective measure to protect passing pedestrians or objects.

High speed spiral door are widely used in underground garages, automobile manufacturing plants, food, chemicals, textiles, electronics, supermarkets, refrigeration, logistics, warehousing and other places, and can meet the needs of high-performance logistics and clean places.
