Cold Room Door Leaf Manufacturing Process
The cold room door leaf manufacturing process requires precise alignment, proper insulation continuity, and strong mechanical fixation. In positive temperature cold rooms, doors must provide effective thermal separation while remaining lightweight and easy to operate.
A standard cold room door leaf consists of:
- Aluminum door leaf profiles
- Ready-made insulated panels
- Inner and outer metal sheets
- Sealing gaskets and mounting accessories
The BOB-AD-183 Aluminum Door Leaf Profile forms the perimeter structure of the door leaf and securely holds the panel in place throughout its service life.
Compatibility with Ready-Made Panel Systems
BOB-AD-183 is fully compatible with 80 mm thick ready-made cold room panels, which are widely used in positive cold room applications. Unlike some other aluminum profiles, this model does not require the use of PVC locking strips.
The profile has a U-shaped geometry, allowing it to completely surround and grip the panel. Thanks to this structure, the panel is mechanically secured directly by the aluminum profile itself, eliminating the need for additional locking elements.
This design simplifies production while ensuring reliable fixation and insulation integrity.
Door Leaf Assembly Method
During manufacturing, the aluminum door leaf frame is assembled using 45-degree angled cuts, forming a rigid rectangular structure. The ready-made panel is then placed inside the U-shaped aluminum profile.
BOB-AD-183 features a dedicated screw channel, allowing installers to:
- Fasten the panel securely through the screw channel
- Lock the structure mechanically
- Cover the screw channel with a matching aluminum channel cover
The channel cover used in this system is BOB-SKP-41A, which is installed after fastening. This cover:
- Protects screws from external exposure
- Improves hygiene
- Provides a clean and professional appearance
No PVC Locking Strip Requirement
Unlike some aluminum door leaf profiles, BOB-AD-183 does not require the BOB-038 PVC strip. The reason is its U-shaped cross-section, which fully encloses the panel edges.
This design offers several advantages:
- Faster assembly
- Reduced component count
- Lower material cost
- Simplified production process
As a result, BOB-AD-183 is considered a more economical aluminum door leaf profile compared to the BOB-7006 series.
Applications in Cold Room Door Systems
The BOB-AD-183 Aluminum Door Leaf Profile can be used in the production of door leaves for multiple cold room door systems, including:
- Cold room hinged door leaf
- Cold room sliding door leaf
- Cold room automatic sliding door leaf
- Cold room monorail sliding door leaf
This versatility makes the profile suitable for a wide range of cold storage projects.
Positive Temperature Cold Room Use
BOB-AD-183 is specifically designed for positive temperature cold rooms, typically operating between 0°C and +10°C. These environments require efficient insulation without excessive door weight.
Typical application areas include:
- Fresh food storage rooms
- Fruit and vegetable cold rooms
- Dairy storage areas
- Food processing cold rooms
The 80 mm panel compatibility ensures sufficient insulation for these applications while maintaining cost efficiency.
Anodized Aluminum Profile Advantages
The BOB-AD-183 Aluminum Door Leaf Profile is manufactured from anodized aluminum, offering significant advantages in cold room environments:
- High corrosion resistance
- Long service life
- Hygienic and easy-to-clean surface
- Improved resistance to moisture and oxidation
- Professional and durable appearance
These properties are essential for doors used in food, pharmaceutical, and industrial cold storage facilities.
Structural Strength and Cost Efficiency
BOB-AD-183 provides:
- Stable door leaf geometry
- Resistance to deformation during long-term use
- Reliable performance under frequent opening and closing cycles
At the same time, its simplified structure and reduced accessory requirements make it more economical than the BOB-7006 series, without compromising essential performance criteria.
