Channel Support Systems Guide

What is a Channel Support System?

A channel support system is a durable framework used to support cable containment, conduit and pipework. Available in a range of configurations, they can be selected to suit different environments, installation requirements and the type of services being routed. Some feature slotted designs for greater flexibility, while others are unslotted for increased rigidity.

What is the Role of Channel Support in Cable Containment?

Support channels are available in several profiles to suit different installation requirements. The most common options include:

• Single strut channel for general cable containment and lighter support applications.
• Pre-galvanised back-to-back strut channel where additional strength and rigidity are required.
• Slotted strut channel with pre-punched slots that provide greater flexibility when positioning brackets, fixings and accessories.

Each option can be combined with compatible brackets, connectors and fixings to create support frameworks that simplify installations in your facility. 

Channel Support Systems Overview 

Channel support systems are available in a wide range of sizes, materials and finishes, with varying load-bearing capacities to suit different installation requirements.

Types of Cable Support Channels 

Cable support channels are available in several configurations to suit different applications and load requirements. Common options include single channels, back-to-back channels and slotted or plain channels.

Materials and Finishes

Pre-galvanised steel is commonly used for internal installations as it provides excellent corrosion resistance. Hot dip galvanised finishes offer enhanced protection for harsher environments where channels may be exposed to more moisture. While stainless steel channels are better suited for outdoor applications where durability is the top priority. 

Load Bearing Capabilities 

Channel support systems play an important role in cable management as they help support the solutions needed to guide and route cables safely and efficiently across different environments. Load-bearing capacity depends on factors including channel profile, span length, fixing method and bracket selection. It’simportant to choose the right load capacity to ensure your cable management systems are safely installed. 

Common Channel Sizing 

Support channels are available in several widths and depths to suit varying installation requirements. The most common lengths for channel supports tend to be 3 and 6 metres. This allows installers to cover long runs efficiently while minimising joints and installation time.

Channel Support Applications 

Cable Tray Support 

Cable trays rely on secure channel support systems to maintain consistent spacing and prevent movement under load. Channels provide a stable framework for brackets, allowing trays to be mounted along walls, ceilings or suspended installations.

Cable Ladder Support 

Cable ladders are typically used for heavier cable installations and require robust support systems capable of carrying substantial loads. Channel supports create strong mounting structures, allowing ladders to span across long distances and still provide essential support. 

Cable Basket Support

Wire mesh cable baskets benefit from lightweight yet secure channel support systems that keep containment level and accessible. The modular design allows installers to easily adapt layouts, making basket systems particularly suitable for commercial buildings and data installations.

Conduit Support

Electrical conduit can be mounted directly to channel support systems using compatible clamps and brackets. Channel supports help create an organised conduit run, while still enabling easy maintenance or simplifying future modifications.

Electrical and Mechanical Installations

Beyond cable containment, channel support systems are widely used throughout electrical and mechanical services installations. They provide versatile frameworks for supporting pipework, HVAC systems, lighting, trunking, containment equipment and associated building services.

Their overall durability and versatility make them suitable across a variety of sectors. Channel supports are beneficial in construction, data centres, warehousing, agricultural, food and beverage, railways, the public sector and nearly any location that requires dependable electrical cable management. 

Types of Channel Support Configuration

Back to Back

Back-to-back channels are formed by joining two channel sections together. This configuration creates a stronger support capable of carrying higher loads. They are commonly used for heavier cable ladders, large pipework and long-span installations where additional rigidity is required.

Single Channel

Single channel is the most commonly used configuration for everyday cable containment. It offers an economical, versatile solution that supports cable trays, baskets and conduit while remaining easy to install, modify and extend.

Cantilever Brackets

Cantilever brackets project horizontally from walls or structural steel to support cable containment without requiring vertical supports beneath. They maximise usable floor space while providing strong support for trays, ladders and baskets.

Angle and Flat Brackets

Angle and flat brackets connect channels together, strengthen frameworks and provide secure mounting points for containment systems. Their versatility allows installers to create bespoke support structures that accommodate varying layouts and site constraints.

Trapeze Supports

Trapeze supports suspend cable containment from ceilings using threaded rod and channel sections. This configuration is commonly used where services need to run overhead while maintaining clear access below for personnel, equipment or vehicles.

Floor Mounted Framework

Floor mounted frameworks provide a stable support structure where wall or ceiling fixing is impractical. Support channels are commonly used to fortify larger mechanical services, plant equipment and heavy containment systems within industrial environments.

Considerations When Choosing a Channel Support System For Your Project

When selecting a channel support system, it’s important to consider:

• Load requirements – Ensure the system is capable of supporting the combined weight of the containment system and installed services.
• Installation environment – Internal, external, corrosive or hygienic environments may require different materials or protective finishes.
• Support configuration – Choose an arrangement, such as cantilever, trapeze or floor mounted, based on the installation layout.
• Distance – Longer spans may require larger channels, additional supports or reinforced configurations.
• Future Expansion – Modular systems make it easier to add new containment or services as building requirements change.
• Compliance – Ensure all support systems meet relevant project specifications and industry standards.
