1. What is cable tray hanging?

Cable tray hangers, also known as ceiling hangers, are products in the cable tray accessory set used for system installation. They are materials with a simple structure. They only consist of a steel rod threaded along the entire body. In addition, there is another type of hanging accessory that is threaded only at both ends of the steel rod.

In design, cable trays are usually not placed too close to the ceiling or basement of a building. Therefore, during installation, supports are needed, including hanging accessories, to create a certain distance so that cables can exit from the bottom of the tray. This system is capable of bearing the heavy load of the cable tray, electrical cable systems, and wires inside to ensure safety for users.

2. When should cable tray suspension be used?

• Ceiling construction:

The ceiling not only serves as a shield but also as a position for hanging cable trays and supporting several other systems in factories, industrial zones, and export processing zones. During the construction process, hanging accessories become a very important type of material that helps connect and suspend various materials to the ceiling such as purlins, cable tray rails, electrical conduit systems, and Unistrut channels.

Before proceeding with construction, engineers need to carefully calculate the appropriate type of suspension so that it has the best durability and load-bearing capacity.

• Wall partition construction:

In addition to ceiling installation, hanging accessories are also commonly used in wall partition construction, combined with steel frames and drywall. The types commonly used in this case are: H-shaped steel bars, I-shaped steel bars, U-shaped steel bars, and V-shaped steel bars.

3. What are the benefits of using cable tray hangers?

Cable tray suspension is widely used in the installation of cable tray systems because it offers many benefits, especially:

• Help the construction process proceed quickly, smoothly, save time, and bring efficiency to the investor.
• Construction and material costs have decreased significantly.
• Manufactured from highly sustainable materials. As a result, damage caused by environmental conditions to the system is minimized.
• Avoid unnecessary risks during use, such as explosions and fires.
• Prevent water from entering the system and prevent attacks from other types of insects.

4. Types of cable tray supports

Cable tray hangers are classified according to many different criteria such as: material, size, surface finish, thread type, strength, etc…

• Classification by size: Common sizes of cable tray hangers include M6, M8, M10, M18, M20, M24, M30, …
• Classified based on the outer coating layer of the product, it can be divided into types such as: stainless steel hangers, white zinc-plated hangers, hot-dip galvanized hangers, etc.
• Classified by thread type, there are usually two common types: square-thread suspension and fine-thread suspension.
• Classified based on durability grade. Each durability grade usually corresponds to a certain load capacity of the cable tray, such as:
• Strength grade 3.6 corresponds to a tensile strength of 300 MPa (3000 kg/cm²).
• Strength grade 4.6 corresponds to a tensile strength of 400 MPa (4000 kg/cm²).
• Strength grade 5.6 corresponds to a tensile strength of 500 MPa (5000 kg/cm²). This is a product with a medium strength grade.
• Strength grade 8.8 corresponds to a tensile strength of 800 MPa (8000 kg/cm²). This is a product type with high strength grade.

5. Technical specifications for cable tray suspension

The technical specifications of the suspension that customers should pay attention to include:

• Diameter: phi 6 to phi 12 (M6 – M12)
• Thread pitch: 1mm – 3.5mm
• Length: 1m, 2m, or according to customer requirements.
• Product surface: galvanized, hot-dip galvanized, black, seven-color electroplated, …

7. Manufacturing suspended cable trays

To ensure product quality, Bestray’s production process always strictly follows the steps below:

• Step 1: Calculate the quantity and dimensions of the product:

Before starting production, the first thing to do is to accurately calculate the dimensions and the number of hanging accessories needed. This is to ensure the

• Step 2: Choose materials for the product:

The materials used in production will greatly affect the quality of the cable tray system later on. Because depending on the environmental conditions, the materials used to make the hanging accessories will also vary. In addition, the raw materials used to manufacture the products also need to be inspected very carefully and meticulously to ensure they are not rusted or deformed.

• Step 3: Cut the product

Based on the dimensions calculated in step 1, the workers will proceed to cut the materials. In this step, the craftsmen are required to have experience and high-level skills to ensure the products are cut to the correct dimensions, avoiding deformation after cutting. The finished products must achieve smoothness, glossiness, and uniformity.

• Step 4: Create threads

After being cut into segments of varying lengths depending on the requirements, the material will then move to the threading machine. Depending on the customer’s requirements, the thread pitch will be created in different sizes.

• Step 5: Check the details

To ensure the product is free from defects and has accurate dimensions after rough machining, workers will carry out a detailed quality inspection. The factors that need attention at this stage include: diameter, length, thread pitch, and cut marks. This inspection is intended to ensure that the product is in the best possible condition, and that any detected errors can be repaired promptly.

• Step 6: Clean the product

Before painting, the product will be carefully cleaned. All dust and impurities will be meticulously removed so that the product will have an even, smooth, and soft paint finish after painting.

• Step 7: Spray paint

The product will be placed in the spray booth after being carefully cleaned. The paint color of this product will usually match the paint color of the cable tray to ensure uniformity throughout the system. The paint layer needs to be applied by experienced technicians to ensure it has the standard color and thickness. This will ensure the product has a beautiful finish and retains its color for a long time.

• Step 8: Inspect and package the products for delivery to the customer.

After completing the above steps, the product will undergo a final inspection. The product must meet requirements regarding quality, dimensions, paint finish, and structural integrity. Once completed, it will be carefully packaged and delivered to the customer.
