PVC high speed door, also known as high-speed flexible roller shutters, are specialised partition doors for industrial automation. They feature a door curtain made of high-strength PVC-coated fabric, combined with a variable-frequency or servo motor and an intelligent electronic control system, enabling high-speed, high-frequency automatic opening and closing.

Their primary functions are to rapidly partition spaces, prevent dust ingress and maintain a constant temperature, and enhance the efficiency of logistics operations; they are commonly used in indoor passageways within factory buildings and warehouses.

PVC High Speed Door Structural Composition

PVC Door Curtains

0.8–1.0 mm thick, coated base fabric with aluminium alloy wind-resistant ribs fitted transversely; can be fitted with long, transparent viewing windows for visibility. The material is wear-resistant, tear-resistant and temperature-resistant from -30°C to 70°C, and is available with flame-retardant, anti-mould and self-cleaning coatings. Colours available include yellow, blue, red and grey.

Door Frame Track

Made from powder-coated cold-rolled steel sheet or industrial-grade aluminium alloy; the track features built-in double-layer sealing brushes, providing a sealed enclosure on all four sides to block airflow, dust and insects.

Drive Drum Assembly

Top-mounted roller door housing, driven by a variable-frequency servo motor, with a lifting speed of **0.6–2.0 m/s**; the full opening and closing cycle takes just 2–5 seconds, and supports frequent operation of over a thousand cycles per day.

Intelligent Electronic Control System

Visual control panel capable of integrating various sensor signals and supporting equipment interlocking (e.g. air showers, assembly lines), with built-in fault self-diagnosis functionality.

Multi-layered Safety Protection

Standard features include infrared photoelectric protection, bottom obstacle detection with safety airbag rebound, and an emergency stop button; optional full-area safety light curtain available. The door automatically reverses upon detecting obstacles during pedestrian or vehicle passage, preventing collisions that could cause injury or damage to goods.

PVC High Speed Door Benefits

Efficient Operation, Energy Saving and Reduced Consumption

PVC high speed door opening and closing speed is 5–10 times faster than that of traditional sheet metal roller shutters. As the door remains open for only a short time, convection of hot and cold air is significantly reduced, lowering energy consumption for air conditioning and cold storage, and delivering long-term savings on operating costs.

Superior Sealing for Environmental Control

A combination of track brushes and a rubber air cushion at the base ensures a complete seal, providing protection against dust, insects, odours and noise, whilst maintaining thermal insulation for both heating and cooling. This stabilises cleanliness, temperature and humidity levels within the workshop, making it suitable for cleanrooms and temperature-controlled warehouses.

Flexible automated control

A variety of opening methods are available: radar sensors, ground-loop sensors, remote control, push-button, pull cord, facial recognition and forklift Bluetooth sensors. The system can be integrated with production lines and AGV robots for coordinated operation.

Durable and Easy to Maintain

The PVC flexible curtain is rust-free and resistant to deformation from impacts; its modular design allows for easy disassembly and replacement of components. It operates quietly and is suitable for 24-hour continuous operation.

High Space Utilisation

The curtain rolls up vertically, occupying no space on either side of the aisle or on the floor, allowing large forklifts and palletised goods to pass through unobstructed.
