Industrial high-speed doors are also known as high-speed rolling shutter doors. They are favored for their high opening speed, excellent sealing performance and diverse application fields. Currently, the commonly used high-speed doors mainly include PVC high-speed doors, rigid high-speed doors, cold storage high-speed doors, stacking high-speed doors and anti-collision high-speed doors.
The operating speed of PVC high-speed doors can reach 1.2 m/s, and they can be opened 500 - 800 times a day with a long service life. The door curtain is made of single-layer industrial fabric, mainly composed of polyvinyl chloride (PVC). It has the characteristics of high strength, wear resistance, corrosion resistance and good insulation. The door curtain can also be customized in different colors such as blue, white, red, gray and fully transparent. Due to the influence of the door curtain material, it is not used alone as an exterior door. It is suitable for places such as the food, pharmaceutical, precision metal, textile, warehousing and logistics industries to play a role in sealing and partitioning. Various intelligent sensing devices such as radar, remote control, geomagnetic, pull rope, Bluetooth opening, face recognition, card swiping access control and AGV linkage can be optionally installed to meet the needs of various different scenarios.
Rigid high-speed doors are also called turbo rigid shutter doors. The opening speed can reach 1.0 to 1.2 m/s, and the closing speed is 0.6 m/s. The structure of the turbo rigid shutter door mainly consists of the door body, driving device, sealing system, control system and safety protection system. The door panel is made of 0.7 mm thick double-layer high-strength aluminum alloy material. The surface has pressed stripes, and the middle is filled with high-density polyurethane foam. The total thickness of the door panel is 43 mm. The track adopts a galvanized plate double-helix guide rail. The door body has a non-contact rolling-up technology and is safely rolled into the spiral track. There is no friction, the door body runs fast, smoothly and quietly, and there is no wear, which greatly extends the service life of the door body. Multiple opening methods such as radar, geomagnetic, pull rope, remote control, Bluetooth opening and face recognition, card swiping access control can be selected.
Cold storage high-speed doors are usually installed in warehouses below zero degrees Celsius. For a normal doorway of 2 - 3 meters, it takes 2 seconds to complete the opening and 3 seconds to complete the closing. Cold storage high-speed doors use multi-layer double-sided high-strength polyester fiber with a thickness of more than 30 mm, which can perform good internal and external heat insulation and heat preservation. Heating wires are installed at the guide rails to effectively prevent water vapor from freezing and affecting the operation of the high-speed rolling shutter door. When the cold storage high-speed rolling shutter door is opened, it is linked with the air curtain machine, which can effectively remove water droplets on the surface of the door curtain and prevent the door curtain from freezing. It can be connected to multiple opening methods such as geomagnetic, radar and pull rope. It is also equipped with various safety devices, such as safety light curtains, airbags, anti-collision columns and door-shaped anti-collision columns, to ensure the safe operation of the door body.
Anti-Collision High-Speed Doors
Anti-collision high-speed doors are also called zipper-type high-speed doors. Their opening and closing speeds can reach 1.2 m/s. The appearance of anti-collision high-speed doors is almost the same as that of PVC high-speed doors. The zipper high-speed rolling shutter door adopts a side zipper structure with a reset mechanism. If the door curtain of this structure falls off the track, for example, due to human impact or accidental collision resulting in the derailment of some connections of the door curtain, its self-repairing system will automatically guide the door curtain back onto the track in the next operation cycle. After the track restoration is completed, the door can still operate normally without manual repair. It has high durability and saves maintenance costs.
Stacking high-speed doors are also called wind-resistant stacking doors. The opening speed is generally 0.6 - 0.8 m/s. They adopt a folding lifting method, and the door curtain can be stacked together when opened, reducing the occupied space. Stacking high-speed doors use multiple built-in horizontal wind-resistant levers, and the wind pressure can be evenly distributed across the entire door curtain. This design enables them to resist high wind speeds, and their wind resistance is stronger than that of other high-speed doors. They are especially suitable for logistics passages and large factory openings.
Industrial high-speed doors are a type of doors with diverse functions. According to different application scenarios and requirements, different types of industrial high-speed doors can be selected. The characteristics of these types of industrial high-speed doors are different, but they can all provide users with functions such as fast opening and closing, energy saving and high efficiency, wind protection, dust prevention, insect prevention and heat preservation, providing important guarantees for the industrial and commercial fields.
