Panel spacer (BOB-PT60) is a component placed between two metal sheets during cold room panel production, before polyurethane injection. The primary function of this panel spacer is to keep the distance between the two sheets fixed at the standard 60 mm dimension.

During application:

• The bottom sheet is laid in position
• The panel spacer is placed between the two sheets
• The top sheet is positioned
• The dimension is preserved until polyurethane injection

This process prevents the top sheet from collapsing, bending, or losing dimensional accuracy before and during polyurethane foaming.

Special Design for 60 mm Cold Room Panels

The panel spacer BOB-PT60 is designed exclusively for 60 mm (6 cm) thick cold room panels. This thickness is widely used in many freezer panels and cold storage panel applications.

By using this panel spacer:

• Panel thickness remains consistent throughout production
• The same dimension is achieved in every panel
• Dimensional uniformity is ensured in mass production

This feature provides a significant advantage for facilities producing large volumes of panels.

Direction-Independent Geometry: Always 60 mm

One of the most distinctive features of the BOB-PT60 panel spacer is its direction-independent geometric structure. Regardless of how the panel spacer is placed between the two metal sheets, it always guarantees a 60 mm spacing.

This means:

• The panel spacer has no orientation (no top, bottom, front, or back)
• Operators do not need to consider placement direction
• Correct measurement is achieved even with random placement

This eliminates operator-related errors and significantly increases production speed. As a panel spacer, BOB-PT60 minimizes dependency on manual precision.

Dimensional Protection Before and During Polyurethane Injection

In cold room panel production, polyurethane injection directly affects insulation performance. During injection, pressure or expansion can cause the top sheet to move downward if not supported correctly.

The panel spacer:

• Prevents the top sheet from collapsing
• Keeps the distance between sheets stable
• Eliminates dimensional loss during polyurethane expansion

As a result, the final cold storage panel is produced with uniform thickness and a homogeneous internal structure.

Easy Fixation: Practical Application with Paper or Nylon Tape

The BOB-PT60 panel spacer can be easily fixed to the bottom sheet using paper tape or nylon tape during production. This fixation prevents the panel spacer from shifting before polyurethane injection.

Advantages of this method:

• No screws or additional fasteners required

BOB-10147 is designed as a modular PVC frame system, allowing cold room door frames to be produced for various wall panel thicknesses using extension profiles.

To achieve the required cold room wall panel depth, the following extension profiles are used:

• 20 mm Extension Profile (BOB-10019)
• 30 mm Extension Profile (BOB-10092)

These extension profiles are added to the main PVC frame profile to match the exact thickness of the cold room wall panel.

How the Modular System Works

• The main PVC frame profile is used as the base component
• If the wall panel thickness exceeds the base depth, extension profiles are added
• Extension profiles are cut at 45-degree angles
• They are installed using a snap-fit (hammer-in) method, without welding
• The required depth is achieved by combining multiple extensions if necessary

This modular approach provides:

• Flexibility for different cold room panel thicknesses
• Reduced inventory complexity
• Faster production and installation
• Consistent frame geometry across different projects

Cold Room Door Frame Production Process

Cold room hinged door frames produced with BOB-10147 follow a structured and efficient manufacturing sequence.

1️⃣ Cutting the Main Frame Profile

The PVC frame profile is measured according to door dimensions and cut at 45-degree angles to ensure precise corner joints.

2️⃣ Frame Assembly

The cut profiles are assembled into a rectangular frame using either:

• PVC welding machines for maximum rigidity, or
• Mechanical joining accessories for faster assembly

3️⃣ Installation of Extension Profiles

Depending on the wall panel thickness:

• BOB-10019 (20 mm) and/or
• BOB-10092 (30 mm)

extension profiles are added to the main frame profile using the snap-fit method. Welding is not required at this stage.

4️⃣ Rear Cover Profile Installation

After the extension profiles are in place, the rear cover profile is prepared:

• It is cut at 45-degree angles
• Welded into a rectangular shape
• Installed onto the extension profiles using a snap-fit method

At this stage, the cold room door frame structure is fully completed.

Why Threshold Sealing Is Critical in Cold Rooms

Cold room doors are not ordinary doors. They form a thermal boundary between two completely different environments. The weakest point of this boundary is almost always the door threshold, due to:

• Floor level tolerances
• Frequent opening and closing cycles
• Heavy trolley and pallet traffic
• Natural wear on the floor surface

Without a proper threshold rubber, cold air escapes at floor level while warm air enters the cold room. This creates condensation, frost formation, and increased refrigeration load. The Cold Room Door Threshold Rubber is designed specifically to eliminate these risks.

Compatibility with Multiple Cold Room Door Types

The Cold Room Door Threshold Rubber (BOB-K83) is engineered for use with a wide range of cold room door systems. It is fully compatible with:

• Cold Room Hinged Doors

Importance of Secure Ceiling Panel Installation in Cold Storage

As previously explained in ceiling suspension system components such as the BOB-TAA101, cold room ceiling panel installation is a direct safety issue, not merely an assembly task. Ceiling panels are exposed to:

• Their own dead weight
• Long spans and wide openings
• Temperature fluctuations
• Long-term mechanical stress

If ceiling panels are not properly suspended, serious risks may occur, including panel sagging, joint separation, thermal leakage, and even panel collapse. Therefore, every fastening element used in the suspension system must be mechanically reliable and perfectly compatible with the carrier profiles.

The Single Square Nut M10 is one of the most important elements in this safety chain.

Function of the Single Square Nut M10

The Single Square Nut M10 is used primarily in cold storage ceiling suspension systems that incorporate Cold Room Ceiling Aluminum Suspension Profiles, specifically:

• BOB-7166 Cold Room Ceiling Aluminum Profile
• BOB-8010C Cold Room Ceiling Aluminum Profile

These aluminum profiles are typically manufactured in 6-meter lengths and feature a special internal channel geometry. The square shape of the nut allows it to fit precisely into this channel, preventing rotation and ensuring a secure mechanical connection.

Once placed inside the aluminum profile channel, the Single Square Nut M10 works together with an M10 threaded metal rod to suspend ceiling panels from the upper structure.

Working Principle with Aluminum Ceiling Suspension Profiles

The suspension system using the Single Square Nut M10 operates as follows:

1. Aluminum ceiling suspension profiles are installed along the ceiling line
2. The Single Square Nut M10 is inserted into the internal channel of the profile
3. The square geometry prevents the nut from rotating inside the profile
4. An M10 threaded metal rod is screwed into the nut
5. The upper end of the threaded rod is fixed to the building’s structural framework
6. Ceiling panels are carried safely via the aluminum profile and square nut

This system ensures that loads are transferred vertically and evenly, rather than being carried only by the panel joints.

Supports Two Ceiling Panels Simultaneously

Due to the geometric design of cold room ceiling aluminum profiles, each profile is capable of carrying two adjacent ceiling panels at the same time. This dual-panel support is only possible when used together with the Single Square Nut M10.

Key advantages of this configuration include:

• Balanced load distribution on both sides of the profile
• Increased structural stability at panel joint lines
• Reduced number of suspension points
• Improved ceiling alignment over long spans

This makes the Single Square Nut M10 especially important in large cold storage rooms where ceiling spans are wide and panel weight is high.

Mandatory Component in Aluminum Ceiling Suspension Systems

The Single Square Nut M10 is not optional in systems that use aluminum ceiling suspension profiles. It is a mandatory fastening element in all installations where BOB-7166 or BOB-8010C profiles are used.

Without this square nut:

• The threaded rod cannot be safely fixed
• The aluminum profile cannot transfer load correctly
• Ceiling panel safety is compromised

For this reason, the Single Square Nut M10 must be used in every aluminum suspension system without exception.

Galvanized or Stainless Steel Construction

The Single Square Nut M10 is manufactured from high-strength metal materials suitable for cold storage environments. Depending on project requirements, it is produced from:

• Galvanized steel sheet, or
• Stainless steel sheet

Material advantages include:

The Double Square Nut M10 is specifically designed to securely connect two 6-meter aluminum suspension profiles back to back, ensuring that the ceiling suspension system functions as a single continuous structural line.

Why Is It Essential in Long Cold Storage Rooms?

In long cold storage rooms or corridor-type cold rooms:

• A single aluminum profile is insufficient
• Multiple suspension profiles must be installed sequentially
• Profile joint points become critical structural zones

Without a proper connection element, these joint points may become weak links in the system. The Double Square Nut M10 eliminates this risk by reinforcing the connection between two aluminum profiles, ensuring continuous load transfer and structural integrity.

This makes it an indispensable component for long cold storage ceilings exceeding 6 meters.

Working Principle and Installation Logic

The Double Square Nut M10 is designed to fit precisely into the internal channel geometry of aluminum suspension profiles. Its square shape prevents rotation and ensures a stable connection inside the profile.

Installation steps:

1. The first 6-meter aluminum ceiling suspension profile is installed
2. The second 6-meter aluminum profile is positioned directly after the first
3. The Double Square Nut M10 is inserted into the internal channel at the joint point
4. The square geometry locks the nut in place, preventing rotation
5. An M10 threaded metal rod is installed through the system
6. The rod connects the joined profiles securely to the upper structural framework

Through this method, two separate aluminum profiles function as one continuous suspension system.

Contribution to Structural Safety

The most important advantage of the Double Square Nut M10 is its ability to maintain structural continuity in long ceiling systems.

This results in:

The Panel Spacer (BOB-PT150) is placed between the lower and upper metal sheets on the cold room panel production line before polyurethane injection. Its primary function is to set and maintain a precise and unchanging 150 mm spacing between the two sheets throughout the entire production cycle.

During manufacturing, BOB-PT150:

• Establishes the correct panel thickness before sheet bonding
• Prevents the upper sheet from sagging under its own weight
• Provides resistance against internal pressure during polyurethane injection

With these characteristics, the product functions not merely as a panel spacer, but as a core dimensional control mechanism for extra-thick panel production.

Purpose-Built Structure for 150 mm Panel Thickness

The Panel Spacer BOB-PT150 is developed exclusively for 150 mm (15 cm) panel production. This focused engineering approach delivers greater stability and reliability compared to general-purpose spacers. Panels of this thickness are widely used in freezer panels and large-scale cold storage panels, where energy efficiency and dimensional precision are essential.

When this panel spacer is used:

• Uniform thickness is achieved across the entire panel surface
• Dimensional fluctuations are completely eliminated
• Installation gaps and alignment issues are prevented
• Thermal insulation performance reaches maximum efficiency

Orientation-Free and Balanced Geometry for Error-Free Placement

One of the most important technical advantages of the BOB-PT150 Panel Spacer is its fully orientation-free and symmetrical geometric design. The spacer:

• Can be flipped

and will always maintain an exact 150 mm distance between the two metal sheets.

This design:

• Eliminates the need for placement direction checks
• Removes operator-related dimensional errors
• Improves production speed and standardization

Such features are especially valuable in high-volume serial manufacturing environments.

Dimensional Stability During Polyurethane Injection

In panels as thick as 150 mm, polyurethane injection generates substantial expansion forces. Without sufficient support, these forces can cause thickness reduction or internal inconsistency.

The Panel Spacer BOB-PT150:

• Prevents downward movement of the upper sheet
• Balances polyurethane expansion forces
• Maintains a homogeneous internal panel structure

As a result, the finished cold room panel fully complies with both dimensional and insulation standards.

Fast, Clean Fixation with Tape

The Panel Spacer can be quickly fixed to the lower metal sheet using paper tape or nylon tape during production. This fixation method:

• Prevents the spacer from shifting before injection
• Requires no screws or mechanical fasteners

Cold room sliding doors are heavy, insulated structures designed to operate reliably under low and negative temperature conditions. Because of their weight and frequent daily use, these doors must be stopped precisely at a predefined position to avoid mechanical damage, misalignment, or safety risks.

The Lower Closing Hook (Stainless Steel) is specifically engineered to:

• Control the final stopping position of the sliding door leaf
• Enter the frame-mounted stopper smoothly and accurately
• Prevent uncontrolled door movement and hard impacts
• Protect both the door leaf and the door frame

During the closing movement, the door leaf travels along the rail system and the Lower Closing Hook (Stainless Steel) engages with the frame stopper (female part). This controlled engagement allows the door to stop smoothly without sudden shock loads.

Working Principle with the Frame Stopper

The Lower Closing Hook (Stainless Steel) operates together with the frame-mounted stopper, identified in the system as BOB-3001 or BOB-3001-SS. These two components form a matched stopping pair, functioning as male and female elements.

Operational sequence:

1. The sliding door leaf approaches the final closing position
2. The Lower Closing Hook aligns with the frame stopper geometry
3. The hook enters the stopper in a controlled manner
4. Kinetic energy is absorbed and the door leaf stops precisely
