PVC Frame Profile (Header Profile) Definition and Structural Role
As a header profile, BOB-10027 defines the primary geometry of the cold room sliding door frame. Its cross-section is intentionally designed without any built-in extensions or depth increases. Unlike L-shaped or multi-level profiles, this profile has a clean and simple geometry, making it the ideal base element for modular frame systems.
This design allows:
- The main door frame outline to be formed accurately
- Frame depth to be adjusted only when necessary
- A fully modular approach to door frame construction
- Simplified production and installation processes
Because it does not include an integrated extension, BOB-10027 provides maximum flexibility when combined with separate extension profiles.
Use in Cold Room Sliding Door Systems
The BOB-10027 PVC Frame Profile is used exclusively in cold room sliding door systems. This includes:
- Manual cold room sliding doors
- Cold room monorail sliding doors
- Cold room automatic sliding doors
In sliding door systems, the door leaf moves horizontally along a rail. For this reason, the door frame must be perfectly aligned and dimensionally stable. The BOB-10027 ensures that the sliding door rail, door leaf, and sealing components work together in harmony.
By forming the main header and side frame geometry, this profile contributes directly to:
- Smooth door movement
- Proper alignment of the sliding mechanism
- Long-term mechanical stability
- Reliable sealing performance
Non-Extended Main Frame Profile Concept
One of the defining characteristics of BOB-10027 is that it is a non-extended main frame profile. This means that the profile itself does not provide additional depth to match wall panel thickness.
Instead, depth adaptation is achieved by adding separate PVC extension profiles. This approach offers several advantages:
- No need for multiple main frame profiles for different panel thicknesses
- Reduced stock complexity
- Faster production planning
- Easier on-site adjustments
This modular concept is a key principle of Bob Modüler’s cold room sliding door frame systems.
Compatible PVC Extension Profiles (With Codes)
The BOB-10027 PVC Frame Profile is fully compatible with all PVC extension profiles used in cold room sliding door frames. These include:
- BOB-10012 – 20 mm PVC extension profile (sliding door systems)
- BOB-10110 – 30 mm PVC extension profile (sliding door systems)
- BOB-10028 – 60 mm PVC extension profile (sliding door systems)
By combining these extension profiles with BOB-10027, frame depth can be precisely adjusted to suit different cold room wall panel thicknesses.
Compatibility with Back Cover Profile (BOB-10014)
After the required frame depth is achieved using extension profiles, the rear-facing side of the frame must be closed. For this purpose, BOB-10027 is fully compatible with the PVC Frame Profile (Back Cover Profile) – BOB-10014.
This compatibility allows:
- Complete closure of the rear frame surface
- Clean and hygienic integration with the wall panel
- A professional and finished appearance
The combination of header profile + extension profiles + back cover profile results in a complete and modular sliding door frame system.
No Integrated Heating Cable Channel
The BOB-10027 PVC Frame Profile does not include a heating (resistance) cable channel. This is a deliberate system design choice for sliding door applications.
In this system:
- The heating cable is not installed inside the frame profile
- Anti-freeze protection is achieved through the door leaf gasket
- The frame structure remains simpler and more compact
This configuration provides important advantages:
- Easier maintenance and replacement of the heating cable
- Reduced processing and machining on the frame profile
- Lower overall system cost
Advantages of PVC Material
The BOB-10027 is manufactured from high-quality PVC material, which is ideal for cold room sliding door frames due to its technical properties:
- Low thermal conductivity, preventing thermal bridges
- High resistance to moisture and condensation
- Hygienic surface, easy to clean
- Corrosion-free and non-oxidizing
- Long service life with minimal maintenance
These features make PVC the preferred choice for PVC frame profiles, cold room PVC profiles, and cold storage door frame systems.
Manufacturing and Installation Process
During sliding door frame production, BOB-10027 is used as follows:
- The header profile is cut to the required door dimensions
- The main frame geometry is assembled
- Wall panel thickness is measured
- Required PVC extension profiles are added
- The rear side is closed using the back cover profile
This process allows fast, clean installation without welding.
