What Type of High-Speed Door Is Best for Parking Facilities?
Introduction
Parking facility entrances vary widely. Some use a single lane for entry or exit, while others have two lanes or separate entrances and exits. Underground ramps can also leave limited space for door installation.
These differences affect the choice of high-speed doors. This article looks at the door options and configurations used in LEFAST parking projects, from underground entrances to wider vehicle access points.
What Does a Parking Facility Need From a High-Speed Door?
High speed doors,with opening speeds above 0.6 m/s, mean high performance doors, help parking facilities manage frequent vehicle movements, maintain a cleaner indoor environment, and improve access control.
1.1 Improve Traffic Flow
Fast opening speeds and automatic activation allow vehicles to pass through with less waiting. For busy parking entrances, doors designed for frequent daily operation help keep traffic moving during peak hours.
1.2 Maintain a Cleaner, More Stable Parking Environment
High-speed doors help limit dust entering the garage and reduce the exchange of indoor and outdoor air. Insulation and sealing can also help protect the garage from outdoor temperature changes and wind.
In regions with large seasonal temperature differences, doors at underground parking entrances can work alongside dehumidification systems to help manage summer humidity. In winter, they can help reduce the chimney effect caused by temperature and pressure differences between the garage and outdoors.
1.3 Improve Access Safety
High-speed doors can be equipped with safety devices such as through-beam photoelectric sensors, light curtains, and safety bottom edges. These help detect vehicles or obstacles and reduce the risk of the door closing against them.
1.4 Support Automated Parking Management
Automatic opening through vehicle detection allows drivers to pass without stopping to operate the door manually. Integration with barrier gates and parking payment systems can coordinate access control and support unattended operation, potentially reducing staffing needs.
Which Types of High-Speed Doors Work Best for Parking Facilities?
High-speed doors can be classified by their curtain or door-panel structure into high-speed fabric doors and high-speed spiral doors. High-speed fabric doors include high speed rolling doors (also called high speed roll-up doors) and high speed folding doors, among other designs. For parking facilities, LEFAST use HPD high-speed folding doors and HSD high-speed spiral doors for common options.
If a folding door meets project actually requirements, it may be the more economical choice; if the site demands stronger environmental protection, a spiral door may be more suitable.
What Does Parking Layout Affect High-Speed Door Selection?
Parking entrances are not all arranged in the same way, may use one door for a single lane, one wide door for two lanes, or two separate doors for entry and exit.
3.1 One Door for a Single Lane
A single door serves one vehicle lane, with its dimensions matched to the required vehicle clearance, then the opening and closing sequence needs to suit the traffic flow.
3.2 One Door for Two Lanes
One wide door can cover two lanes, whether traffic moves in the same direction or in both directions.The overall opening width and required clearance need to be considered alongside the traffic layout.
3.3 Two Doors for Separate Entry and Exit
Two doors can operate independently, with one assigned to entry and the other to exit. In one LEFAST underground parking project, two HPD2000 high-speed folding doors were installed with vehicle detection for automatic opening.
3.4 When Side Space Is Limited
When there is insufficient space for two doors side by side, LEFAST can assess an offset column arrangement, positioning adjacent columns at different depths to fit the site layout.
3.5 Separate Vehicle and Pedestrian Access
A larger vehicle door can be paired with a smaller door for pedestrian access or other separate traffic, depending on the project requirements.
What Does the Installation Location Affect Door Requirements?
The location of a parking entrance affects the door’s exposure to wind, available installation space, and sealing requirements.
4.1 Above-Ground Parking Entrances
Above-ground entrances are directly exposed to outdoor conditions. Wind resistance, weather protection, and the frequency of vehicle access should be considered when selecting high speed doors.
4.2 Semi-Underground Parking Entrances
At semi-underground entrances, the door may be installed partway along a ramp. The slope, available headroom, and surrounding structure can limit where the door and its tracks are installed.
4.3 Fully Underground Parking Entrances
At fully underground entrances, the door is typically installed near the bottom of the ramp. Limited overhead or side clearance may affect the installation, while sealing and integration with the parking control system may also need attention.
How Do Headroom and Side Clearance Affect Door Selection?
5.1 When Overhead Space Is Limited
Low headroom can restrict how a door opens without reducing the required vehicle clearance. For high-speed spiral doors, different track configurations—including round spiral, oval spiral, and horizontal lift—can be assessed according to the available space and opening dimensions.
5.2 When Side Clearance Is Limited
Columns, walls, and adjacent openings can restrict where the door can be installed. In some projects, positioning adjacent door columns at different depths allows two doors to fit within a limited side space. The feasibility depends on the site layout and the door structure.
5.3 When Standard Configurations Do Not Fit
If a standard configuration cannot meet the site requirements, the door type and installation layout may need to be reassessed together. The goal is to maintain the required clear opening while accommodating overhead obstacles, side restrictions, and the available installation space.
How Can High-Speed Doors Support Smart Parking Systems?
6.1 Vehicle Detection for Automatic Opening
Induction loops and radar sensors can trigger the door to open as a vehicle approaches. But for the parking facilities on the ramp geometry, radar is not better choice because of obstruction its detection angle or affect the detection area.
6.2 Integration With Barrier Gates and License Plate Recognition
High-speed doors can be integrated with barrier gates, license plate recognition, and parking management systems. This makes entry and exit easier to manage and supports automated operation with less manual intervention.
6.3 How Can High-Speed Doors Support Smart Environmental Control?
When connected to a suitable building management system, high-speed doors can coordinate with ventilation and dehumidification equipment. This helps parking facilities manage airflow and humidity more effectively while limiting unwanted air exchange between indoor and outdoor spaces.
How to Choose the Right High-Speed Door for a Parking Facility
The right door depends on the opening size. traffic flow, available installation space, wind exposure, operating frequency, and control requirements.
7.1 Which Door Fits Different Parking Applications?
Underground parking entrances with limited headroom: Check the available headroom before choosing a door model. In one underground parking project with opening W3500*H2800, the available headroom was less than 550 mm, with insulation requirement LEFAST installed an HSD23116 high-speed spiral door whose head design fitted the space while meeting the project's operating requirements.
HSD23116 is one option for low-headroom installations. The right choice depends on the opening dimensions and the space available for the door and its tracks.
Separate entry and exit lanes: Two independently operated doors can keep incoming and outgoing traffic separate. In one underground parking facility, installation location did not require high wind resistance , two HPD2000 high-speed folding doors were installed, with ground induction loops trigger automatic opening when vehicles approach.
A folding door was the economic choice to meet the project's needs. The door type should be selected according to the conditions at the entrance.
Wide openings serving two vehicle lanes: A wide opening needs to provide sufficient clear passage while keeping the door panels structurally suitable for the span. In one project, the building opening was 9.2 m wide, and the required clear passage was more than 8.5 m. We supplied HSD8022 spiral doors provided an 8.5 m clear passage.
Panel strength and the risk of deformation were key considerations during selection. For wide doors, confirm both the required passage dimensions and whether the panel structure is suitable for the opening.
Special-purpose vehicle garages: These projects may involve vehicle dispatch requirements, safety controls, and restrictions imposed by the building structure. One customized garage project required a clear passage of W 10m by H 5m, with the door coordinated with a central command center.
The building had a structural frame with columns spaced just over 10 m apart. The door columns needed to sit close to the building's structural columns, so the existing structure had to be considered in the installation layout. LEFAST supplied a customized HSD10022 solution for the project.
7.2 What Common Mistakes Should You Avoid When Choosing a Parking Facility Door?
Choosing by opening size alone
The door may fit the building opening without providing the clear passage needed by vehicles. Wide spans also require attention to panel strength and potential deformationBefore selecting a model, confirm the required clear width and height, vehicle clearance, and structural requirements.
Ignoring installation constraints until after selecting the door
Low headroom, limited side clearance, structural columns, and adjacent openings can affect both the door configuration and its installation. Check these conditions early. If a standard arrangement does not fit, reassess the door type and overall layout together rather than assuming that a configuration change will always solve the problem.
Assuming every parking entrance needs the same door type
High-speed folding doors and high-speed spiral doors serve different requirements. If the site's wind resistance, insulation, and sealing needs can be met by a folding door, it may be a suitable option. Where higher performance is required, a spiral door may be more appropriate. The decision should follow the project's actual requirements rather than a blanket preference for one type.
Overlooking controls and system integration
A door that operates independently may not meet the needs of an automated parking facility. Consider how vehicle detection, barrier gates, license plate recognition, and parking management systems need to work together. At ramp entrances, the detection method should also suit the ramp geometry and the intended detection area.
7.3 What Should You Confirm Before Finalizing a Door Solution?
Before selecting a high-speed door, confirm the following:
Opening dimensions: Required clear passage width and height, including the dimensions of the vehicles using the entrance.
Installation space: Available headroom, side clearance, structural columns, and potential obstructions.
Traffic layout: Single lane, two lanes through one opening, or separate entry and exit doors.
Performance requirements: Wind resistance, insulation, sealing, and safety devices.
Operating demands: Expected daily opening-and-closing cycles and the required level of automation.
System integration: Compatibility with vehicle detection, access control, and parking management systems.
Operating history can also help when assessing a door for frequent use. An LEFAST HSD4322 installed in a residential parking facility has recorded 1.77 million opening-and-closing cycles over more than six years. This provides a reference, though performance in another facility will depend on its operating conditions, maintenance, and installation.
