Direct Central Passage
The two moving leaves open away from the center, creating a clearly defined passage through the middle of the entrance. The required passage width must be reviewed together with the complete structural opening.
Center-Opening Sliding Entrances
Bi-Parting Automatic Sliding Door
Two moving door leaves open away from the center to create a direct central passage. Plan the entrance around the required clear opening, usable travel space on both sides, door-leaf construction, sensing and control requirements.
- Symmetrical center-opening movement
- Clear central passage
- Coordinated sensing and access control
Product Definition
What Is a Bi-Parting Automatic Sliding Door?
A bi-parting automatic sliding door uses two moving leaves that meet at the center when closed and travel in opposite directions when opening. The movement creates a central pedestrian route and a balanced entrance appearance.
The complete entrance may include fixed side panels, glazed or framed moving leaves, an overhead operator, activation sensing, presence-safety detection, operating controls, locking interfaces and project-defined access-control connections.
When Does This Layout Fit?
Consider a bi-parting layout when the project requires a central opening and has usable door-travel space on both sides. The final arrangement still depends on the structural opening, target clear passage, door-leaf dimensions and weight, façade conditions and system interfaces.
If the required passage cannot be achieved with the available side space, another sliding-door product direction, such as a telescopic arrangement, should be reviewed.
Decision Benefits
Why Consider a Bi-Parting Layout?
Balanced Entrance Design
Center-opening movement supports a symmetrical façade composition and keeps the pedestrian route aligned with the visual center of the entrance.
Coordinated Two-Way Movement
A central passage can support users approaching from both directions when the opening time, sensing zones and surrounding circulation are planned around the actual traffic pattern.
Flexible Project Configuration
Door leaves, frames, glass, operator system, sensors, controls, locking and supply scope can be reviewed according to the project. Final options depend on verified dimensions, loads and interface requirements.
Selection Conditions
Confirm Six Conditions Before Choosing a Bi-Parting Layout
Structural Opening
Confirm the full opening width and height, and identify whether the dimensions are structural, finished, or preliminary.
Required Clear Passage
Confirm the usable passage required when the door is fully open. This affects the moving-leaf and fixed-panel arrangement.
Side Travel Space
Confirm the usable travel area on both sides. Columns, walls, glazing lines, façade details and other obstructions may affect the layout.
Door-Leaf Construction
Confirm the proposed leaf dimensions, frame system, glass, hardware and estimated or verified leaf weight.
Traffic and Sensing
Describe approach directions, peak traffic, wheeled access and the required activation and presence-safety sensing zones.
Access and Supply Scope
Confirm access-control, locking and operating-mode requirements alongside the complete-door scope and work by others.
Layout Comparison
Bi-Parting or Telescopic?
| Selection point | Bi-Parting Sliding Door | Telescopic Sliding Door |
|---|---|---|
| Opening movement | Two moving leaves travel away from the center | Multiple leaves slide and stack in sequence |
| Space condition | Requires usable door-travel space on both sides | Consider when side travel space is more restricted |
| Passage position | Creates a central passage | Passage position depends on the selected layout |
| Main review points | Symmetry, central route and travel space on both sides | Leaf stacking, pocket space and opening utilization |
This comparison is a planning guide rather than a fixed engineering rule. Final selection requires the opening dimensions, leaf construction and operator configuration.

Typical System Components
The final supply scope should be confirmed project by project. A complete bi-parting entrance may include the following components.
Automatic Door Operator
Houses the drive, controller and supporting mechanisms above the entrance.
Motor and Belt Drive
Transfers controlled movement to the two door leaves through the selected operator configuration.
Controller
Coordinates opening, closing, speed, hold-open time, operating modes and connected signals.
Track and Hangers
Support and guide the moving leaves; selection depends on the door construction and verified load.
Activation Sensing
Detects an approaching user or receives an approved activation signal.
Presence-Safety Detection
Monitors defined areas around the threshold and door path according to the selected sensing arrangement.
Access and Locking Interface
Connects compatible access-control, operating-mode and locking functions where required.
Door Leaves, Fixed Panels and Frames
Complete the entrance according to the approved layout, material, finish and glazing specification.

Frequently Asked Questions
What is a bi-parting automatic sliding door?
A bi-parting automatic sliding door has two moving leaves that meet at the center when closed and travel in opposite directions when opening, creating a central passage.
How much side space does a bi-parting door require?
It depends on the required clear passage, moving-leaf dimensions, fixed panels, frame system and operator arrangement. Provide the full opening width and the usable space on both sides for layout review.
How are the opening size and door-leaf weight confirmed?
The review uses the structural opening, required clear passage, leaf dimensions, glass, frame, hardware and verified or calculated leaf weight. Final values must match the selected operator configuration.
What sensors are required?
Sensor selection depends on the approach directions, pedestrian flow, threshold and monitored areas. Activation and presence-safety functions may be combined or provided by separate devices according to the configuration.
Can the door connect to an access-control system?
Compatible card readers, keypads, face-recognition devices, reception controls or building systems can be reviewed. Signal type, controller logic, locking and device compatibility must be confirmed before supply.
Can SEPPES supply a complete door or only the operator?
Our main focus is complete door supply. Operator systems, components and accessories are generally supplied to existing customers as replacement, spare or repair parts. Large-volume standalone requirements, such as hundreds or thousands of sets, can be discussed separately. The quotation lists inclusions and exclusions.
What affects the price of a bi-parting automatic sliding door?
Price depends on the opening, door-leaf construction and weight, operator, sensors, controls, access and locking interfaces, finish, quantity, supply scope, packaging and destination.
What must be confirmed before production?
Confirm the entrance dimensions, clear passage, side travel space, moving leaves, fixed panels, supporting structure, power, sensors, access control, locking and the responsibilities of each party.
