A C strut channel, also known as strut channel, C-channel, or strut, is a versatile metal framing system commonly used in construction and industrial applications for supporting electrical conduits, pipes, HVAC systems, and other structural components. The "C" shape refers to its cross-sectional profile, which resembles the letter "C," providing strength and rigidity while allowing for easy installation of various accessories like clamps, brackets, and fasteners.

• Sizes:

  • Standard widths are usually 41 mm (1 5/8 inches).
  • Depths vary, with common sizes being 21 mm (7/8 inch) and 41 mm (1 5/8 inch) for light to medium-duty applications.
  • Can be produced in longer lengths, typically 10 feet (3 meters) or 20 feet (6 meters), and can be cut to size as needed.

• Slotted or Plain:

  • Slotted: Channels have pre-drilled slots along the length, allowing for easy adjustment and alignment of mounting hardware.
  • Plain: Channels without slots, typically used where more rigidity is required           

Channel Finish/ Special Metals

Most Unistrut Channel is available in Plain Carbon Steel, Perma-Green, or Pre-Galvanized finish. Other options include hot-dipped galvanized and special metals (aluminum and Type 304 & 316 stainless steel). Though other finishes can be used to weld, plain carbon steel (no finish, black steel, bare steel), which has only a light coating of oil, to help prevent rust, is typically the preferred 'finish' for welding.

Carbon steel is no good for outdoor environments or environments with a lot of moisture or corrosive elements. Carbon steel will rust over time. It can however be hot dipped, powder coated or painted. So it might make sense if you are using it in the manufacture of something, which you plan to apply a finish to after production has been completed.

Perma-Green and Pre-Galvanized are the most common finishes and offer a decent amount of protection against humidity, weather and chemical/corrosive agents. Hot-dipped galvanized finish is similar to pre-galvanized, but has a thicker, more robust layer of galvanizing, while special metals, like aluminum and stainless steel, provide their own unique set of benefits.

Applications of C Strut Channel

1. Electrical Systems:

   • Commonly used to support electrical conduits, cable trays, and wiring systems in commercial and industrial buildings.

2. Mechanical Support:

   • Provides support for pipes, HVAC systems, ductwork, and other mechanical systems.

3. Framing and Mounting:

   • C strut channels are widely used to construct framing systems for lightweight structures such as shelving, racks, or equipment stands.

4. Solar Panel Mounting:

   • Used in the installation of solar panels, providing a strong, adjustable framework for mounting on roofs or ground installations.

5. Plumbing:

   • Strut channels support pipes and plumbing systems, helping to keep them aligned and securely in place.

6. Industrial Construction:

   • Often used in factories, warehouses, and industrial plants to mount heavy machinery, equipment, or ventilation systems.
