Channel & Supports

Channel (Unistrut): Versatile Support for Cable Management and Beyond

Channel, often referred to by the brand name Unistrut, is a versatile metal framing system widely used in electrical installations, mechanical support, and various construction applications. This adaptable solution provides a robust framework for supporting cable management systems, pipes, HVAC equipment, and much more.

Standard Specifications

Channel is typically supplied in 3-meter lengths, offering a convenient size for transportation, handling, and installation. This standard length allows for efficient use of material while minimising waste on job sites. The channel comes in two main profile sizes:

1. 41x41mm: This square profile offers equal strength in both axes, making it suitable for a wide range of applications, especially where multi-directional support is needed.
2. 41x21mm: This smaller profile is ideal for lighter-duty applications or where space is at a premium. It's commonly used for wall-mounted supports and in tighter spaces.

Channel Types

Channel is available in two main types:

1. Slotted: The most common type, featuring continuous slots along its length. These slots allow for easy attachment of various fittings and accessories, providing maximum flexibility in positioning and adjustments.
2. Plain: This type has a smooth surface without slots. It's used in applications where a clean appearance is desired or where the continuous slots are not necessary.

Both types are typically made from pre-galvanized steel, offering good corrosion resistance for indoor use. For more demanding environments, hot-dip galvanized or stainless steel options are often available.

Unitrunk: A Leading Brand

While Unistrut is often used as a generic term for channel, other brands like Unitrunk offer high-quality channel systems. Unitrunk is known for its comprehensive range of cable management solutions, including channel systems that are compatible with their other products.

Unitrunk's channel offerings adhere to industry standards, ensuring compatibility with a wide range of accessories and fittings. Their products are recognized for their durability, ease of installation, and versatility across various applications.

Accessories and Fittings

One of the key advantages of channel systems is the wide array of accessories available, which greatly expand their functionality. Some common accessories include:

1. Window Brackets: These allow for the mounting of equipment or cable trays away from the wall or ceiling, creating space for access or ventilation.
2. Supports: Various types of supports are available, including L-brackets, U-brackets, and threaded rod hangers, allowing for secure mounting in different orientations.
3. Channel Nuts: These slide into the channel and provide a threaded fixing point for bolts, allowing for easy attachment of equipment or other components.
4. Joiners: Used to connect lengths of channel for longer runs or to create structures.
5. End Caps: These cover the ends of the channel for a neater appearance and improved safety.
6. Pipe Clamps: Designed to secure pipes or conduits to the channel.

Applications in Cable Management

In the context of cable management, channel plays a crucial role in creating support structures for cable trays, ladder racks, and other cable routing systems. Its versatility allows for custom configurations to suit specific installation requirements. For example:

• Wall-mounted channel can support vertical cable runs.
• Ceiling-mounted channel can create a framework for suspended cable trays.
• Floor-mounted channel structures can support heavy-duty cable management systems in industrial settings.

The ability to easily adjust and modify channel-based supports makes it ideal for installations where future changes or expansions are anticipated.

Conclusion

Channel, whether from Unitrunk or other manufacturers, is an indispensable component in modern electrical and mechanical installations. Its standard 3-meter lengths, 41x41mm and 41x21mm profiles, and slotted or plain options provide a flexible foundation for a wide range of applications. When combined with an extensive selection of accessories like window brackets and supports, channel systems offer nearly limitless possibilities for creating custom, efficient, and adaptable support structures for cable management and beyond.
