The main types of stacking doors
Standard stacking door:

The most common type is when the door panels are stacked upwards directly above the doorway.

Suitable for places with a certain clearance above the doorway (usually requiring a doorway height plus about 30-50cm of space).

Vertical lifting stacking door:

Lift vertically up a short distance first, and then bend and stack.

This can better avoid some minor obstacles above the door opening, such as pipes and lighting fixtures, but requires slightly higher clearance.

Low clearance stacking door:

This is a major advantageous variant of the stacking gate. Specially designed for places where the space above the doorway is very narrow (even only 20-30cm).

By optimizing the guide rail and torsion spring system, opening can be achieved in extreme spaces.

Core strengths
Low space requirements: the biggest advantage. There is no need to reserve a large amount of space on both sides or above like sliding doors or quick rolling shutter doors, which is very suitable for old factories or compact spaces.

Strong wind resistance: Due to the use of multiple hard door panels hinged together, the overall structure is sturdy and can withstand large wind pressures. It is commonly used for large exterior door openings.

Good sealing performance: The door panel is equipped with high-quality sealing strips on both sides and the top, and has an elastic rubber bottom edge at the bottom, which can effectively prevent wind, dust, sound insulation, and thermal insulation.

Durable and sturdy: The door panel material is sturdy (such as color steel plates or stainless steel plates with a thickness of 0.4mm or more), the guide rail is thick, and the overall service life is long.

High safety: usually equipped with airbags (which will bounce back when the bottom edge touches an obstacle) or wire rope breakage protection devices.

Comparison with Quick Doors
This is a common confusion point, and their differences are very obvious:

Characteristic Stacking Door Quick Door
Door material: Hard board (metal, PVC board), Soft PVC door curtain
Slow opening speed (about 0.1-0.3 meters/second), smooth and extremely fast (0.8-2.0 meters/second), efficient
Core functions include isolation, insulation, wind resistance, theft prevention, fast passage, frequent opening, and sealed partitions
Applicable frequencies: low frequency (dozens of times per day), ultra-high frequency (hundreds or even thousands of times per day)
Space requirements: A small amount of clearance is needed above the door opening, and a large scroll space is needed above the door opening
Good sealing performance (hard sealing), very good (soft airbag sealing)
Mainly used for factory exterior doors, warehouse doors, workshop interior partitions, passages, and cold storage
Main application scenarios
The exterior doors of factories and warehouses: as the main entrance and exit, they are required to be wind resistant, insulated, and anti-theft.

Garage entrance: especially for large industrial garages and fire stations.

Logistics channel: a channel that requires sealing but does not have extreme traffic frequency.

4S stores and repair workshops require large-sized, aesthetically pleasing, and sturdy doors.

Key points for purchasing
Door panel material and thickness: Common types include color steel plate, polyurethane foam filling board (with good insulation), and stainless steel plate. Choose according to wind resistance, insulation, and anti-corrosion requirements.

Motor power: Select the appropriate motor power based on the size and weight of the door to ensure smooth pulling.

Safety configuration: Airbags are a very important configuration and must be equipped.

Quality of guide rail: High quality galvanized steel plate guide rail is the key to the smooth operation of the door body.

Clear space is required
