In This Guide
What Is a Cable Tray?
A cable tray is a rigid support structure used to route and support insulated electrical and communication cables along walls, ceilings, floors or designated service areas. It forms part of a cable management system that keeps wiring organized and accessible throughout an installation.
Unlike electrical conduits, which enclose cables within pipes, many cable trays use an open or partially enclosed design. This allows technicians to inspect cable routes, identify wiring and make modifications when required.
Cable trays are manufactured in different configurations, including perforated, ladder-type, solid-bottom and wire mesh designs. They are also available in materials such as mild steel, galvanised steel, stainless steel and aluminium, depending on the application.
A complete cable tray system may include straight sections, bends, tees, reducers, covers, couplers, brackets and support structures. These components work together to create a continuous and well-organized cable route. Learn more about the available cable tray accessories.
What Are the Different Types of Cable Trays?
Selecting the appropriate cable tray depends on cable weight, installation environment, ventilation requirements and available space. Below are the most common cable tray types.
1. Perforated Cable Tray
A perforated cable tray is manufactured from a metal sheet with regularly spaced openings along its base. These perforations allow ventilation while providing continuous support for cables.
Perforated trays are widely used in commercial buildings, industrial facilities, electrical installations and control systems. They offer a practical balance between cable support, accessibility and airflow.
Key benefits:
- Supports different types of electrical and control cables.
- Allows ventilation through perforations.

3. Solid-Bottom Cable Tray
A solid-bottom cable tray features a continuous base without the regular perforations found in perforated designs. It can be considered for applications requiring a more continuous supporting surface.
These trays may be suitable for certain control, instrumentation and communication cable installations. However, cable temperature, ventilation, environmental exposure and manufacturer recommendations should be evaluated before selection.
Key benefits:
- Provides continuous base support.
- Helps contain loose cable components within the tray.
- Can be used in installations where an open base is unsuitable.
- Supports organized routing when selected for the correct cable type.
4. Wire Mesh Cable Tray
Wire mesh cable trays, also called basket cable trays, are constructed from welded metal wires. Their lightweight, open design makes them useful for structured cabling and communication systems.
They are frequently used in data centres, IT rooms, office networks and telecommunications installations.
Key benefits:
- Lightweight and convenient to handle.
- Provides good airflow around cables.
- Allows flexible routing in suitable installations.
- Makes cable additions and inspection relatively straightforward.

5. Channel Cable Tray
Channel cable trays are compact cable support systems designed for smaller cable groups and shorter routing distances. They are often used in equipment connections, control wiring and building services.
Their compact design makes them useful where installation space is limited or where a smaller cable support arrangement is sufficient.
Key benefits:
- Suitable for smaller cable runs.
- Requires relatively little installation space.
- Supports organized wiring around equipment.
- Can simplify routing in compact installations.
What Materials Are Used in Cable Trays?
Cable tray material selection affects corrosion resistance, mechanical performance, service life and overall project cost.
Galvanised Iron (GI) Cable Tray
GI cable trays use zinc-coated steel to provide corrosion protection. They are commonly considered for indoor electrical installations and industrial environments where the specified coating is suitable.
Hot-Dip Galvanised Cable Tray
Hot-dip galvanised trays receive a zinc coating through a hot-dip galvanising process. They are frequently used in outdoor installations and industrial environments requiring suitable corrosion protection.
Stainless Steel Cable Tray
Stainless steel trays are suitable for applications where corrosion resistance and durability are important. Depending on the stainless steel grade and operating conditions, they may be used in food processing, pharmaceutical facilities and demanding industrial environments.
Aluminium Cable Tray
Aluminium cable trays are lightweight and naturally resistant to corrosion under many conditions. They can be useful where reduced structural weight and ease of handling are important.
Powder-Coated Cable Tray
Powder-coated trays feature a protective surface finish that can improve appearance and provide additional surface protection. Their suitability depends on the coating specification and environmental conditions.
