The term "high-speed door" usually refers to a door with a **quick opening and closing function**, mainly used in places that require frequent passage, high efficiency, or isolation of different environments.

Quick Door Parameter Description

The term "quick door" usually refers to a door with a **quick opening and closing function**, mainly used in places that require frequent passage, high efficiency requirements, or the need to isolate different environments. Depending on the application scenario, "quick door" can refer to the following types:

1. Industrial High-Speed Roll-up Door: 
* Most common type. Widely used in factories, warehouses, logistics centers, cold storage, clean rooms, parking lot entrances and exits, etc.
* Core features: 
* Extremely fast speed: Opening and closing speeds can reach 0.6m/s to 2.5m/s or even higher, far exceeding ordinary roll-up doors or sliding doors. This greatly reduces passage waiting time and improves logistics efficiency. 
* High-frequency operation: Designed for hundreds or even thousands of opening and closing cycles per day, it is sturdy and durable. 
* Good sealing: The bottom of the door curtain usually has a rubber seal, and the sides have brushes or rubber seals, which can effectively isolate dust, insects, odors, moisture, hot and cold air, etc., maintaining the indoor environment (such as cleanliness, temperature). 
* High safety: Standard safety photoelectric (infrared light curtain) forms a protection area at the bottom of the door body. When encountering obstacles, it immediately stops closing and rises to prevent pinching people or objects. Some door frames also have safety airbags (edge contact) at the bottom.
* Various curtain materials: PVC soft curtain (transparent, translucent, opaque, with different thicknesses and colors available, anti-tear fiber can be added), metal curtain (aluminum alloy or steel anti-wind blades), insulation curtain (with internal insulation material), etc., to meet different needs. 
* Various drive methods: Servo motor (high precision, fastest speed, most flexible control), variable frequency motor (adjustable speed, smooth start and stop), brake motor, etc. 
* Various control methods: Button switch, rope switch, remote control, radar induction (automatic door opening when people or vehicles approach), geomagnetic induction (vehicle presses the induction coil to open the door), swipe card, linkage access control system, access to the central control system, etc. 
* Wind resistance: According to the size of the door opening and the requirements, there are designs with different wind resistance levels (usually achieved by strengthening the guide rail, door curtain structure, or adding wind resistance rods).

2. Construction Site/Temporary Passage Quick Door: 
* Usually refers to a simple quick passage door made of PVC soft curtain or canvas material, installed on a temporary frame. 
* Features: Quick installation and removal, low cost, can play a basic role in isolation (dust, noise), windproof, insulation (limited), and indicating the passage. Often used in construction sites to separate areas, temporary entrances and exits for large-scale events, etc.

3. Home/Commercial Quick Sliding/Folding Door: 
Although not the "extremely fast" speed in the industrial field, in home or commercial spaces (such as balconies, kitchen partitions, shop entrances), some well-designed sliding doors or folding doors are also called "quick doors", emphasizing their convenient opening and closing and space-saving features. 
* Features: Light and smooth operation, large opening range or can be completely folded and retracted, saving space, and beautiful. The material may be aluminum alloy, glass, wood, etc.

In summary, when people mention "quick door", it most likely refers to:

* Industrial high-speed roll-up door: This is the most mainstream, technologically advanced, and widely used type. Its core value lies in **speed, efficiency, sealing, safety, and durability**.

To better understand the "quick door" you are referring to, could you provide more information? For example:

* Where is it used? (Factory workshop? Warehouse entrance and exit? Cold storage? Parking lot? Construction site? Home balcony?)
* What is the main purpose? (Improve passage efficiency? Insulation? Dust prevention? Sound insulation? Windproof? Safety protection?) 
* What are the specific requirements for the door? (Size? Switching speed? Sealing requirements? Insulation requirements? Wind resistance requirements? Is automatic induction required?)

Understanding your specific needs will allow us to more accurately recommend or explain the corresponding "quick door" type and characteristics.
