Structural Features Of Zipper-Type High-Speed Doors

Mar 12, 2026 Leave a message

Zipper-type high-speed doors are specially designed for industrial scenarios that require high frequency, high cleanliness, and high sealing standards.

 

Core Structural Features

Zipper-type Engaged Sealing System
Industrial-grade zipper racks are embedded on both sides of the door curtain and closely engage with C-shaped or U-shaped rubber/nylon guides within the track, forming a physical locking structure similar to a "clothing zipper." This achieves nearly zero-gap 360° sealing, effectively blocking dust, insects, airflow, and temperature differences exchange.

 

Integrated High-Strength PVC Door Curtain
Made of double-layer or thickened anti-static PVC material (usually ≥0.8mm thick), with a smooth non-adhesive surface. Some models include transparent windows for enhanced safety and practicality. The door curtain is a single-piece structure without segments, improving wind resistance and collision performance.

 

Automatic Reset (Collision Recovery) Function
If the door curtain is derailed due to external forces like a forklift, the built-in reset mechanism can automatically guide the door curtain back into place during the next operation, without manual intervention, significantly reducing downtime and maintenance time.

 

Low-Noise Fully Soft Door Design
The door body contains no metal parts (such as wind bars in traditional rolling shutters). It moves solely via the zipper and guide tracks, producing very low noise, suitable for environments requiring quiet operation.

 

High-Speed Drive System
Equipped with a servo motor and reduction mechanism, the opening speed can reach 1.8–2.5 m/s, and the closing speed 0.6–1 m/s, meeting the needs of hundreds of operations per hour.

 

Compact Guide Structure
The guide width is usually only 8–10 cm, reducing dust accumulation points, saving installation space, and enhancing structural stability.

 

Multiple Safety Configurations
Standard configurations include safety light curtains, infrared sensors, and bottom safety airbags, which automatically stop or rebound when obstructed, ensuring personnel and equipment safety.
