PERFORATED CABLE TRAYS: AN IN-DEPTH LOOK
Perforated Cable Tray plays a crucial role in ensuring the safe and optimal operation of the electrical wiring and cabling system. Currently, the use of Perforated Cable Trays in factories, buildings, and apartment complexes has become very common. This system is seen as a way to protect wires and cables and allow for easy replacement if necessary.
Thanks to this, their lifespan is extended, and they are protected from failures and environmental factors. In the article below, Bestray will provide essential information for you to understand more about Perforated Cable Trays.
1. An Overview of Bestray Perforated Cable Trays
The Perforated Cable Tray is considered a support system for installing and protecting various types of power distribution cables, insulated conductors, and communication signal cables.
What is a Perforated Cable Tray?
The Perforated Cable Tray is designed in a rectangular box shape with perforations on the bottom and sides. Its function is to secure the conductors. Nowadays, buildings, apartment complexes, production workshops, etc., are often equipped with Perforated Cable Tray systems. This makes the process of installing, dismantling, and replacing the system much easier.
2. When to Use Perforated Cable Trays
Typically, people use Perforated Cable Trays for installation in the wiring and cabling system of apartment buildings, high-rise buildings, manufacturing facilities, etc. Their function is to protect communication signal cables or power distribution cables.
In industrial and commercial construction, the Perforated Cable Tray is often installed to help manage the system. Specifically, if you need to modify the wiring system, this installation is very convenient and useful. This is because, instead of having to install through a conduit, you simply place the new cable in the Perforated Cable Tray.
3. Perforated Cable Tray Manufacturing Materials
3.1. Aluminum Perforated Cable Trays
According to Technical Bulletin No. 13 of the Cable Tray Institute, one of the important choices when designing corrosion-resistant or outdoor cable tray systems is the material. Cable tray systems with a Hot-Dip Galvanized (HDG) finish (ASTM A-123) have been successfully used for many years. However, contractors and industrial engineers are starting to favor aluminum over hot-dip galvanizing.
The reasons are very simple. Aluminum Perforated Cable Tray systems have been shown to have many advantages in design, installation, distribution, performance, and overall cost throughout their lifespan.
Aluminum Perforated Cable Trays have a superior strength-to-weight ratio compared to hot-dip galvanized cable trays. Aluminum is also superior to HDG in that when cut in the field, it does not require cold zinc spray, which is inferior in quality compared to the original galvanizing. Therefore, when you cold-galvanize a bare metal piece, you do not restore the full strength and protection of the original coating.
In contrast, Aluminum alloy 6063-T6 has excellent corrosion resistance in a variety of environmental chemicals compared to HDG, and is sometimes referred to as marine-grade.
Aluminum can be cut or scratched and still maintain its corrosion resistance without the need for a protective coating. When Aluminum 6063-T6 trays are used with stainless steel hardware, the system can operate continuously with little or no degradation over time.

5. Perforated Cable Tray Manufacturing Process
Step 1: Receive and understand customer needs To ensure customers get the most satisfactory product, the first step before manufacturing Perforated Cable Trays that Bestray focuses on is clearly understanding the purpose and usage needs. From there, we can easily calculate the appropriate size and material for the product. To increase the service life and durability of the Perforated Cable Tray, we conduct actual surveys and precise measurements.
Step 2: Select the appropriate Perforated Cable Tray material Depending on the environmental conditions, we will advise on the suitable material for the Perforated Cable Tray. Some of the most commonly used materials comprise:
- Powder-coated black steel
- Hot-dip galvanized steel
- Stainless steel
In addition, other technical specifications such as length, width, and detailed thickness are needed for the design drawing.
Step 3: Cut according to the determined size In this step, Bestray proceeds to cut the steel sheets according to the predetermined Perforated Cable Tray size. The raw material for making the Perforated Cable Tray must have the required thickness, ensure quality, and be free of rust or warping.
Step 4: Perforating/Punching process Depending on the designed drawing, the product will be perforated according to requirements. Bestray uses CNC technology, a modern technology with high precision and aesthetics. Thanks to this, the product always achieves the best quality.
Step 5: Product forming After the perforating process, the product is transferred to the bending machine. The parameters for ratios and dimensions are pre-set. Thanks to this, the Perforated Cable Tray is quickly bent, welded, and firmly shaped.
Step 6: Surface inspection, pre-painting treatment After rough processing the product, all joints and welds need to be carefully checked in detail. At the same time, technical specifications such as length, width, and thickness also need to be checked accurately. Once approved, the surface treatment is performed on the rough product.
Step 7: Cleaning, washing, painting, and surface drying The rough product surface will be thoroughly cleaned according to the correct standard, depending on the surface coating technology. This is a crucial step to ensure that the Perforated Cable Tray when finished has a beautiful and durable coating over time. After cleaning, the Perforated Cable Tray surface will be coated according to customer requirements.
Step 8: Inspection, packaging, and delivery to the customer After completion, the Perforated Cable Tray will undergo a final inspection. This step is to ensure that the Perforated Cable Tray has a solid structure, meets the size requirements, is free of dents or warping, has high aesthetics, and matches the customers request. Then, the Perforated Cable Tray will be carefully packaged and transported to the customers address.
