automatic doors

Automatic doors are a convenient and accessible entry solution for commercial buildings, shopping centres, airports, and hospitals. They offer seamless entry and exit, energy efficiency, and enhanced accessibility. The main types of automatic doors include sliding, swinging, telescoping, and revolving doors, each with its unique advantages and disadvantages.

Sliding Doors

  • Space-efficient as they do not require clearance for opening.
  • Offer smooth and fast operation, ideal for high-traffic areas.
  • Can be single, double, or telescopic, providing flexibility in design.


  • Can be more expensive due to the complexity of the mechanism.
  • Require regular maintenance to ensure smooth operation and safety.

Swinging Doors


  • Automatically return to the closed position, ensuring the door is seldom left open, which is good for energy conservation.
  • Suitable for both single and double door configurations.
  • Can be equipped with sensors to open only when needed, reducing energy loss.


  • Require clearance space for opening, which may not be suitable for tight spaces.
  • May pose a risk of hitting someone on the swing side when opening.

Telescoping Doors


  • Provide a wider opening than standard sliding doors, making them suitable for areas requiring large entryways.
  • Offer efficient use of space and can accommodate high traffic.
  • Ideal for retail and commercial spaces where large openings are desired.


  • More complex mechanisms can lead to higher initial costs and maintenance requirements.
  • May require more space for the door panels to retract, depending on the configuration.

Revolving Doors


  • Excellent for energy efficiency as they minimise air exchange between indoor and outdoor environments.
  • Can handle high traffic while maintaining a constant entry and exit flow.
  • Serve as an airlock to reduce dust and noise from outside.


  • Require a significant amount of space, making them less suitable for smaller entrances.
  • Higher initial investment and maintenance costs compared to other types of automatic doors.
  • May not be as accessible for people with disabilities or those using carts or strollers without additional accessibility features.


When choosing an automatic door, consider the specific needs of the building, including traffic flow, space availability, energy efficiency, and accessibility requirements. Each type of automatic door has its benefits and limitations, and the best choice depends on the application and the priorities of the building owner or manager. Regular maintenance is crucial for all types of automatic doors to ensure their reliability, safety, and longevity.

The Components of a Commercial Sliding Automatic Door System

Door panels

These are the moving parts of the door system, typically made of aluminium, glass, or a combination of both. Door panels can be single, double, or telescopic, depending on the required opening width and space constraints.

Door track

The door track is the horizontal rail that guides the door panels’ movement. It can be mounted on the floor, the ceiling, or both, depending on the door type and installation requirements.

Rollers or trolleys

These components are attached to the door panels and glide along the door track, allowing smooth and controlled movement.


Sensors detect the presence of people or objects in the path of the door, triggering the opening and closing mechanism. Common types of sensors include infrared, microwave, and ultrasonic sensors.

Door operator

This is the “brain” of the automatic door system, housing the motor, control unit, and power supply. The door operator processes signals from the sensors and sends commands to the motor, controlling the door panels’ movement.

How a Commercial Sliding Automatic Door Works


As a person or object approaches the door, the sensors detect their presence and send a signal to the door operator.


The door operator processes the sensor signal, determines if the door should open, and sends a command to the motor.


Upon receiving the command, the motor activates the rollers or trolleys, causing the door panels to slide along the track and open.


The door remains open for a preset time, allowing people or objects to pass through. The timing can be adjusted to accommodate different traffic levels and accessibility requirements.


Once the preset time elapses or the sensors detect that the doorway is clear, the door operator sends a command to the motor to close the door panels.

Advantages of Commercial Sliding Automatic Doors


Automatic doors provide barrier-free access, making buildings more inclusive for people with disabilities, seniors, and families with strollers.

Energy efficiency

By opening only when needed and closing promptly, automatic doors minimise heat loss and reduce energy consumption, contributing to a greener environment.


Automatic doors offer a hands-free, hassle-free experience, making it easier for people to enter and exit buildings while carrying items, pushing carts, or using mobility aids.


With built-in sensors and safety features, automatic doors can prevent accidents and injuries by detecting obstacles and stopping the door panels from closing.

Commercial sliding automatic doors have revolutionised the way we interact with buildings, providing accessibility, convenience, and energy efficiency. By understanding the components and processes behind these doors, we can appreciate the complex technology that makes our daily lives more seamless and comfortable. Next time you walk through a sliding automatic door, take a moment to marvel at the engineering and innovation that makes it possible.
