Contemporary commercial buildings require sophisticated wiring, networking, security, and telecommunications facilities. Whether it’s a corporate building, shopping centre, hospital, school, or any other IT park, thousands of wires are installed in the facility for seamless functioning. Proper and efficient wire management is a must in such cases; that is why cable management has become one of the key features of modern infrastructure.
Out of the various types of cable support systems currently in use, the perforated cable tray happens to be one of the most sought-after systems for commercial buildings. Durable, with great ventilative qualities, flexible, and easy-to-maintain, the perforated cable tray represents a reliable way to manage the cables of electricity and telecommunications.
This article by Simco Steel provides you with reasons behind the use of perforated cable trays in commercial buildings, advantages, available sizes of the perforated cable trays, installation requirements, supporting systems, and costs involved.
Understanding Perforated Cable Trays
A perforated cable tray is an arrangement used for supporting cables whereby holes or perforations are incorporated uniformly into the base and sides of the cable tray. These holes improve airflow and ventilation while ensuring that there is proper structural support of the cables. With this feature, it becomes easier to ventilate the cables to improve their performance while still maintaining the integrity of the cable.
Unlike the enclosed conduits, which limit accessibility, the perforated cable tray allows open access to cables. This means that you will find it much easier to work on the cables by replacing or even adding new cables. This comes in handy in a commercial setting where there may be changes to cables in the future.
The flexibility of a perforated cable tray is best seen in its capacity to hold various types of cables in one arrangement. For instance, you could have your power, communication, network, fire alarms, and security cables held together in one arrangement.
Why Commercial Buildings Prefer Perforated Cable Trays
There is a need for safe, scalable, and economically feasible methods of routing cables within commercial buildings. In addition to meeting all of these criteria, perforated cable trays provide extra benefits as well.
1. Superior Ventilation and Heat Dissipation
Perforated cable trays have better ventilation capabilities. When electrical cables conduct electricity, they emit some heat. Excessive heat build-up will result in faster wear and tear and, ultimately, lower efficiency of the system.
Hence, good ventilation is important, since it helps dissipate some heat. With their superior ventilation capabilities, perforated cable trays make an excellent choice for commercial buildings.
These buildings tend to contain large and complex electrical and computer systems, and proper ventilation can improve their longevity greatly.
2. Efficient Cable Management
Perforated cable trays facilitate proper management of cables. Modern commercial buildings have hundreds of thousands of cables that traverse many stories, departments and sections of the building.
Therefore, a systematic management of cables is very important. It not only decreases the risks of damage but also helps with maintenance. Most owners prefer perforated cable tray systems because they suit current requirements and are easy to expand later on.
3. Strength and Durability
In commercial applications, a cable tray system is expected to last for extended periods without compromising its integrity. To achieve this objective, a well-constructed GI perforated cable tray delivers excellent strength and outstanding resistance to corrosion.
The zinc-based layer on the tray acts as a protective barrier against environmental elements and rusting. Contractors often find GI perforated cable trays appealing due to their durable and economical nature.
Standard Perforated Cable Tray Sizes
Selecting the appropriate dimensions for a perforated cable tray is important since it helps determine whether there will be enough space for cables and future upgrades. Usually, perforated cable tray sizes may comprise:
| Width (mm) | Height (mm) | Typical Application |
| 50 mm | 25 mm | Small Communication Cables |
| 100 mm | 50 mm | Networking Systems |
| 150 mm | 50 mm | Control Wiring |
| 300 mm | 50 mm | Commercial Power Cables |
| 450 mm | 75 mm | Mixed Utility Cables |
| 600 mm | 100 mm | Large Commercial Installations |
There are numerous considerations when choosing the right perforated cable tray sizes. These include:
- Number of cables
- Cable diameter
- Future expansion requirements
- Load capacity
- Building design
It is common to find multiple perforated cable tray sizes employed in commercial buildings to cater for different groups of cables in such structures.
Benefits of GI Perforated Cable Trays
‘GI’ stands for ‘Galvanised Iron Perforated Cable Trays‘, and its main benefits include the following:
- Excellent corrosion resistance
- Long service life
- High load-bearing capacity
- Low maintenance requirements
- Cost-effective performance
Since commercial buildings must function efficiently for decades, GI perforated cable trays have been commonly used to organise structured cables in such buildings.
Perforated Cable Tray Installation Best Practices
Proper perforated cable tray installation will be important to ensure that you can optimise its performance in the future. There are many things that you need to do when installing your cable trays so that you can guarantee that you get good results.
Route Planning
This step entails designing routes for your cable tray properly so that there will be no congestion in the system. This step will be important to ensure easy access to the tray for maintenance in the future.
Load Assessment
Engineers should undertake a load assessment through the calculation of the total weight in the trays. Calculating loads will enable you to choose the right tray size that will ensure appropriate support, ventilation, and loading capacity.
Segregation of Services
If there are power cables and communication cables installed in the building, they need to be segregated in order to avoid electromagnetic interference. Segregating different services will also make it easier to conduct maintenance work in the future.
Safety Compliance
In order to install cable trays safely, you should ensure that they meet all the relevant safety standards and regulations in your area. Doing so will be critical to ensuring both present and future safety and performance of the cable tray.
Proper installation and professional execution of your cable tray installation project will yield optimum performance. Proper installation will reduce future maintenance costs by avoiding problems such as improper loading and congestion.
Importance of Perforated Cable Tray Support
An effective perforated cable tray support system is indispensable to ensure that the tray remains stable and structurally sound. The perforated cable tray support structure will carry the weight of the tray itself and all the cables within it. Some of the common ways to support the tray include using:
- Wall-mounted brackets
- Ceiling suspension rods
- Cantilever arms
- Trapeze hangers
- Floor-mounted supports
Correctly designed spacing between support units is crucial to avoid sagging and ensure structural strength throughout its service period.
Factors Affecting Perforated Cable Tray Price
A variety of factors determine the perforated cable tray price. These factors include:
- Material type
- Tray thickness
- Tray width and depth
- Galvanization process
- Load requirements
- Installation complexity
- Project scale
The cost might be different in case standard or customised trays need to be utilised. However, despite the higher price tag initially, the overall cost of the trays will eventually decrease because of durability and low maintenance levels.
