Pvc fast door

High-Speed Hard Door, also known as aluminum alloy fast door, is simply called hard fast door. It is a new type of metal fast door for anti-theft and high-temperature isolation. It is reliable, practical and easy to operate. Hengxing Metal High-speed Rolling Door is a high-tech product developed  by introducing advanced foreign technology. The advent of the  metal high-speed rolling door has brought a new concept to industrial doors. The technology is at the world's leading level. It can maintain good sealing performance under both high and low pressure. It can also resist strong winds exceeding 120 km/s. The opening speed of the door varies with its size and can reach up to 2.5 m/s at the fastest. This door not only has a beauti- ful appearance but also features high practicality, reliability, durability, ease of operation and low noise. It is the best choice for busy entrances and exits in various fields such as chemical industry, pharmaceuticals, automotive industry and food processing.

Hengxing  Hard  Quick  Door  uses  airbags  in  its  defense  system.  The  infrared electro-optical and grating protection system can be turned on in a safer and more  reliable way  using  Bluetooth,  geomagnetic,  card  swiping,  license  plate recognition, 2.4G, induction probe, and other methods. Underground parking lots have centralized entrances and exits with large opening capacity, high wind pressure, and harsh environment, which require very high door requirements. Ordinary garage doors cannot meet the requirements. Linte hard quick doors can open up to 3000 times a day, and can withstand windspeeds of ≥ 12 levels. They  have  good  insulation  and  fast  opening  and  descending  speed,  making them the preferred product for underground parking entrances and exits.

Infrared safety protection switch

A  pair  of  infrared  radiation  switches  should   be   placed  500mm above the ground on the door frame pillar for safety. When pedes- trians or objects pass through the door when it descends, the door will automatically bounce back to the most open position.

Magnetic line safety switch

Bury a  magnetic coil on the ground  under the door. When  larger metal objects such as forklifts or cars pass through, the magnetic coil converts the information of the metal cutting magnetic lines in the  magnetic  field  into  a  signal  and  transmits  it  to  the  control system. The control system responds promptly by pulling the door to the most open position.

Bluetooth RF

Bluetooth RF activation technology allows objects to open the door when they are close to it, without the need to open the window or swipe the card.

Infrared safety light curtain switch

This is a safety system consisting of a set of 1800mm high infrared transmission and reception switches arranged in a uniform array of 20, installed in the direction of the entrance and exit of the door opening. Its protection surface is larger, minimizing blind spots as much as possible in terms of safety. Installing 40 sets of probes for the entrance and exit of the door opening is equivalent to 40 sets of infrared safety switches.
