Understanding Elevator Door Applications: Single Speed, Two Speed, Center Part, and Bi-Parting Freight Doors


Elevator doors play a crucial role in the overall functionality, safety, and efficiency of vertical transportation systems. The type of door used can significantly impact the performance of the elevator, especially in different applications and environments. In this blog, we will explore four common types of elevator doors: single speed, two speed, center parting, and bi-parting doors. We’ll detail their characteristics, typical applications, and the benefits they offer.


Single Speed Doors

Description: Single speed doors, also known as single slide doors, consist of one panel that moves horizontally to open and close. These doors operate at a consistent speed throughout their movement.




  • Residential Buildings: Commonly used in residential buildings due to their simplicity and cost-effectiveness.
  • Small Commercial Buildings: Suitable for small commercial buildings where traffic is relatively low.
  • Limited Space Areas: Ideal for buildings with limited space, as they require minimal horizontal clearance.


  • Cost-Effective: Typically less expensive to install and maintain compared to more complex door systems.
  • Simplicity: Easy to operate and maintain, with fewer components that can fail.
  • Space-Saving: Requires less space to operate, making them suitable for narrow elevator shafts.


Two Speed Doors

Description: Two speed doors consist of two panels that move horizontally, with one panel sliding behind the other. This configuration allows for faster opening and closing times compared to single speed doors.




  • High-Traffic Areas: Ideal for high-traffic environments where quick access is essential, such as office buildings and shopping centers.
  • Commercial and Industrial Buildings: Used in settings where speed and efficiency are crucial, like hospitals and warehouses.
  • Modern Residential Complexes: Suitable for modern residential complexes with higher traffic volumes.


  • Faster Operation: Reduces waiting times due to quicker opening and closing.
  • Durability: Designed to handle frequent use in demanding environments.
  • Enhanced Efficiency: Improves overall efficiency of the elevator system, especially during peak usage times.


Center Parting Doors

Description: Center parting doors consist of two panels that meet in the center and slide horizontally away from each other to open. They provide a balanced and symmetrical appearance.




  • Large Freight Elevators: Commonly used in freight elevators that need to accommodate bulky or wide items.
  • Automotive Industry: Ideal for transporting vehicles and large parts within manufacturing plants.
  • Bulk Storage Areas: Suitable for areas where large volumes of goods are moved frequently.


  • Wide Opening: Provides a larger opening, facilitating the movement of large items.
  • Balanced Load Distribution: Evenly distributes the weight of the door panels, reducing wear and tear.
  • Aesthetic Appeal: Offers a symmetrical and professional look.


Bi-Parting Doors

Description: Bi-parting doors, also known as bipartite doors, consist of two panels that split horizontally, with one panel moving up and the other moving down. This unique design allows for a wide opening without requiring additional horizontal space.



  • Limited Space Environments: Ideal for environments with limited horizontal space but requiring a wide opening.
  • Heavy Industry: Used in heavy industrial settings where large and heavy items are frequently moved.
  • Specialized Applications: Suitable for specialized applications, such as clean rooms or areas with specific spatial constraints.


  • Space Saving: Maximizes available space by eliminating the need for horizontal clearance.
  • Wide Access: Provides a large opening, accommodating bulky and heavy items with ease.
  • Versatility: Can be adapted to various industrial applications with specific space and access requirements.



Choosing the right elevator door for your building is essential for ensuring efficient and safe operations. Single speed, two speed, center parting, and bi-parting doors each offer unique benefits tailored to different applications.
