In busy industrial facilities, traditional rolling doors often face a dilemma: keeping the door open for convenient access leads to temperature loss, humidity imbalance, and dust intrusion, while frequent manual operation slows workflow and wastes valuable production time.
To solve this problem, Hongfa Door Industry has introduced a next-generation high speed door solution — combining durable construction with intelligent radar sensing technology.
With the concept of “automatic opening for people and vehicles, and fast closing when idle,” it helps maintain a stable indoor environment while improving traffic efficiency, making it an ideal replacement for traditional automatic roll up doors in modern factories.
Durable Structure and High-Speed Performance: Built for Heavy-Duty Operation
The Hongfa High-Speed Rigid Door is designed for continuous use in high-traffic areas.
Each door panel is 40mm thick, built with double-sided aluminum alloy and a high-density polyurethane foam core, and sealed with EPDM rubber strips between sections to form an airtight barrier.
Strong Structure: This design provides outstanding wind resistance, thermal insulation, and tight sealing, while withstanding thousands of cycles per day — perfect for production workshops, logistics corridors, and clean areas.
Fast Operation: The door opens at speeds up to 1–2 m/s, closing immediately after passage. This minimizes air exchange and energy loss, helping factories maintain consistent temperature and humidity while reducing HVAC costs.
Long Lifespan: With wear-resistant tracks and a durable drive system, Hongfa doors ensure reliable performance and lower maintenance needs even under constant operation.
Smart Radar Sensing: Seamless and Automatic Access
One of the biggest advantages of the Hongfa system is its smart radar sensor, which brings true automation to everyday factory operations.
Automatic Detection: The radar unit can be installed above or beside the door to precisely detect moving targets such as people or forklifts, automatically triggering the door to open without manual touch.
Smooth Traffic Flow: Once a person or vehicle enters the detection zone, the door opens instantly and closes automatically after a short delay — saving time and improving logistics efficiency, especially for busy factory entrances.
Enhanced Safety: Adjustable radar sensitivity and detection range work alongside infrared sensors and safety airbag edges, ensuring that doors never close on people or equipment. It’s a perfect balance between safety and speed.
