Cable trays are construction materials used inside buildings to hold courses, cables, and wires without damaging them. Rather than routing wires over the roof space and exposed partitions, these cable trays allow installers to run them inside a shaped path. 

Trays can ensure security wires are protected, or information is transferred around the structure by managing whatever types of electrical cables are required. Although exact procurements might differ, most national and local construction standards require cable trays to be used in various capacities.

With technological advances, there is a greater need for effective bolstering routines. Nowadays, buildings and plants are more likely to be computerised. The complex type of cable and wiring lying has become an essential piece of modern business and structure by offering prompt, versatile, and inadequate answers to these difficulties. Cable Tray Manufacturers have responded to this demand by introducing several types of cable trays.

What is the importance of choosing the right cable tray material?

Generally, cable trays are included in systems that support cables and wires for power and communication. A cable tray system is designed to accommodate both power and signal cables while providing easy upgrades, expansions, reconfigurations, or relocations of networks.

Types of Cable tray


Ladder-Type Cable Tray


Ladder cable tray manufacturing consists of two rails joined by rungs. Cables can easily be accessed from the top or bottom of this cable tray because of the ladder rungs.

Cable trays with ladder rungs can tie down cables in non-horizontal cable runs and save cable placements in horizontal cable runs.

Solid Bottom Type Cable Tray


It is recommended to use cable trays with solid bottoms (without vents) when installing fibre-optic cables, as drooping cables could negatively affect the system’s performance. Electromagnetic/radio-frequency interference is a major reason for using solid-bottom trays.

Perforated Cable Tray


The cable holder has perforations on the bottom, and the side rails are ventilated so that you won’t get moisture in your cable. Cables are better supported with this tray than ladder-style cable trays.

Channel Type Cable Tray


A channel cable tray is a metal tray that can be used for even the most modest cable installations. It comes in a variety of designs.

Wire Mesh Cable Tray

Wire Mesh Cable Tray

A wire mesh cable tray, also called a basket cable tray, is a cable tray made out of stainless steel wires that create a basketlike mesh.

Cable Tray in different industries

Commercial constructions


Whether it is a building, industry, or construction, a cable tray supports electrical wiring for power supply in any building, industry or construction. It is generally used in open wiring systems, where many wires and air circulation are required to maintain them.

Oil and Gas


Fuel extraction and manufacturing facilities have some of the harshest environments, which makes tray cable ideal for use in these facilities because they are in harsh environments.



Mining environments are notorious for their hazardous conditions, including explosives and high temperatures. Tray cables may be ideal for this kind of environment, but not all tray cables are suitable due to the differences in insulation and jacketing combinations.

Wastewater Treatment Plants


There is a high moisture level in wastewater treatment plants compared to mining environments. Tray cable is versatile enough to be used in wastewater treatment plants, not just in dry conditions but also in wet ones.

Electrical Co-generation


For these facilities, cable jacketing and insulation must be carefully chosen according to the specific needs. For wind turbine applications, the Wind Turbine Tray Cable (WTTC) is an example of a tray cable used in electrical co-generation.
