What is a High-Speed Door? Structure and Applications

Nowadays, traditional doors no longer meet the requirements for opening and closing speed, causing a waste of time and energy. This is where high-speed doors become a breakthrough solution. Designed with superior opening and closing speeds, effective insulation, and dirt resistance, high-speed doors not only improve productivity but also ensure a safe and clean working environment.

This article will delve into the definition, detailed structure, practical applications, and pricing of high-speed doors, helping you gain an overview and make the right investment decision for your business.

What is a high-speed door?

High-speed doors (English: High-speed door or Rapid roll door) are a type of industrial door designed to open and close at extremely high speeds, typically from 0.6m/s to 2.5m/s. This speed is much faster than standard rolling doors, helping to shorten opening and closing times, thereby minimizing heat loss and preventing dust and insects from entering production areas or warehouses.

In particular, PVC high-speed doors are the most common type, using curtains made of thick PVC fabric that is durable, tear-resistant, and easy to clean. This type of door is often equipped with sensors or automatic controls, helping to optimize traffic flow and ensure safety for people and vehicles when using dock levelers.

Detailed structure of high-speed doors

A high-speed door operates effectively thanks to the combination of many strictly designed components:

Door Curtain

This is the main component of PVC high-speed doors. The curtain is made of high-quality PVC material, with a thickness of 0.8mm to 2.0mm, reinforced with load-bearing bars to increase rigidity and wind resistance. The curtain comes in various colors, often transparent in some positions for easy observation.

Door Frame

The frame is usually made of powder-coated steel or stainless steel, ensuring sturdiness and corrosion resistance. The door frame not only acts as a support for the entire system but also guides the curtain during opening and closing.

Motor and Transmission System

This is the “soul” of the high-speed door, determining speed and operating performance. The motor is usually a servo motor or a high-capacity three-phase motor, integrated with an intelligent controller to precisely adjust the opening and closing speed.

Control System and Sensors

To optimize the operation process, high-speed doors are equipped with modern control devices and sensors.

Control panel: Allows users to set operating modes and control the door.

Photoelectric sensor: Detects obstacles when the door is closing, automatically reversing to avoid collision.

Radar: Detects the movement of people or vehicles from a distance, automatically opening the door.

Push button, remote, or pull cord: Direct control methods.

Anti-collision System

Some high-end rapid roll door lines have a special design, allowing the curtain to automatically detach from the frame upon collision and automatically return to the original position, helping to minimize damage.

Applications of high-speed doors

With superior advantages, rapid roll doors are widely applied in many fields:

• Manufacturing plants: Installed at access points between workshops, helping to prevent dust, noise, and maintain stable temperatures, especially in food, pharmaceutical, and electronics manufacturing plants.
• Cold storage, freezer warehouses: High-speed doors help minimize cold air loss every time the door opens, significantly saving electrical energy.
• Logistics and warehousing: Installed at loading and unloading doors, helping forklifts and other vehicles move quickly without interruption, thereby increasing handling productivity.
• Shopping centers, supermarkets: Used at goods receiving areas or areas needing space separation, ensuring hygiene and safety.

How much is a high-speed door?

High-speed door prices are not fixed but depend on many factors:

1. Door dimensions: The larger the size, the higher the material and production costs.
2. Brand and origin: High-speed doors from reputable brands, imported from Europe, often have higher prices compared to products manufactured in Asia.
3. Materials: Curtain materials (standard PVC, fire-resistant, anti-static…) and frame materials (powder-coated steel, 304 stainless steel…) will directly affect the cost.
4. Features and accompanying technology: Integrating additional devices such as radar, safety sensors, UPS, or anti-collision systems will increase the high-speed door price.
5. Installation and warranty services: Installation costs and warranty or maintenance packages are also part of the total investment cost.

In general, high-speed door prices range from tens to hundreds of millions of VND, depending on the configuration and specific needs of each project.
