4. Types of supports/brackets/holders

Currently, to ensure the installation and use of cable tray and ladder systems are secure and have good load-bearing capacity, different types of cable ladder supports are used depending on the specific situation. Below are some of the support types that are commonly used on the market today.

4.1. The letter U

The U-shaped support bracket is a common product line. It is used when a cable ladder or cable tray system needs to run close to a wall. In this case, the bracket is drilled into the wall at a 90-degree angle. The cable ladder or tray is then mounted onto the bracket and secured together with screws.

4.2. Suspended ceiling on a sloped ceiling surface.

In areas with sloped ceilings, the product commonly used to support cable tray systems is a sloped ceiling hanger bracket. It allows the cable tray system to fit closely against the ceiling, increasing usable space and enhancing aesthetics. This type of support accessory is designed to be mounted flush to the ceiling, creating a flat shelf. As a result, the cable tray can be securely accommodated within the surface area.

4.3. Cable tray ladder support frame

For ceiling-mounted vertical cable tray systems, the most commonly used product is the cable tray suspension frame. This type of support bracket is designed differently depending on usage requirements, including:

• Cable tray ladder hanging bracket.
• Cable tray ladder hanger frame with a spacer pad.
• Cable tray ladder hanger bracket with a two-branch spacer pad.
• Cable tray ladder hanging frame with detachable symmetrical mounting ends.
• Cable tray ladder hanging bracket with a detachable asymmetric mounting head.
• Detachable cable tray ladder hanging bracket.
• Ceiling-mounted crossbar

4.4. Wall hanging painting(s)

Another type of support bracket used for parallel wall mounting, intended to secure and bear the load of cable ladder and cable tray systems, is called a wall support arm for cable ladders and cable trays. Similar to cable ladder and cable tray hanging frames, wall support arms also come in various types such as:

• Wall-mounted bar
• Sloped wall-mounted bar
• Wall-mounted bar with a cushion pad.
• Wall-mounted rod connector

4.5. Redirection frame

For sewer systems requiring diversion during installation and use, you need to use frame diversions. There are two commonly used types of diversions:

• Wall-mounted diversion frame
• Steel skirt-mounted deflection frame.

Depending on the installation location, you can use different types of mounting accessories to ensure safety and convenience.

5. Bracket Specifications

Cable tray mounting accessories have several important technical specifications, such as:

• Four oval holes are punched in the part that contacts the wall.
• Longer than cable ladders, cable trays, and cable ducts by 5-7 cm.
• The part that contacts the cable tray has two oval holes punched in it to prevent it from shifting.
• The stand is usually large and wide to provide stability.
• The thickness of the support bracket is typically 2.0mm ~ 5.0mm
• Depending on the requirements, the support frame will be powder coated, electro-galvanized, hot-dip galvanized, ZAM steel, etc…
• The simple design of the stand makes it easy to mass-produce.

6. Price quotation for the stand

7. Manufacturing of support frames

Bestray cable tray supports are manufactured using a standardized process to ensure the highest product quality.

• Step 1: Calculate the SWL load and the dimensions of the cable tray support.

Before production begins, the SWL load and dimensions of the cable tray support must be carefully calculated to ensure compliance with the project’s technical requirements. All types of supports must be designed and tested for SWL load according to TCVN 10688:2015 (IEC 61537:2006) Section 10.8. This ensures that the support accessories perform their function effectively within the system, facilitating smooth installation and safe operation.

• Step 2: Choose the type of stand and stand material.

Cable tray supports come in various types, such as U-shaped supports, sloping ceiling supports, cable tray hanging frames, wall-mounted cable tray support bars, and redirecting frames. The type of support accessory chosen will depend on the specific location.

In addition, depending on the environmental conditions, the materials and surface treatments for the support brackets also need to be selected appropriately. Some commonly used materials include: powder coating, electro-galvanizing, hot-dip galvanizing, ZAM sheet metal, etc…

In addition, before production begins, it is necessary to carefully calculate the technical specifications regarding the length, width, and thickness of the accessories.

• Step 3: Cut the workpiece according to the technical drawing.

Based on the calculated technical drawings, workers will proceed with cutting the sheet metal. The cut sheet metal must be accurate in dimensions, smooth, free from rust, and not warped.

• Step 4: Hole punching

After being cut, the sheet metal will be fed into a CNC machine and punched with holes according to the design. The support brackets need to be precise to ensure smooth and aesthetically pleasing installation.

• Step 5: Shaping the product

After the holes have been punched, the product will be transferred to a bending machine to form the desired shape and support structure as previously determined and designed.

• Step 6: Inspect the product before painting.

Cable tray support accessories will undergo careful inspection to ensure accurate specifications compared to the drawings regarding thickness, length, width, and quantity. Once the requirements are met, the product will proceed to the surface treatment step.

• Step 7: Surface treatment

The support frame will undergo a thorough cleaning to ensure a durable and aesthetically pleasing finish. After cleaning, the product will be painted in the color requested by the customer.

• Step 8: Final check, packaging, and delivery to the customer.

The final step in the cable tray support manufacturing process is quality control. The supports must be of the correct quantity and dimensions according to the technical drawings. The product must have a sturdy structure and an even, smooth paint finish.
