What is Strut Channel Framing? FAQ & More
Strut channel framing refers to a modular metal framework commonly used in construction and engineering. Strut channels are versatile structural components that support electrical, mechanical, and plumbing systems. Their unique design allows for easy assembly and adjustment when combined with fittings and hardware, making them popular in both industrial settings and DIY projects. This guide will explore the various aspects of strut channel framing, from its applications and technical specifications to installation tips and economic considerations.
While Unistrut is the go-to brand name in the strut channel world, many brands now offer the same quality & options. We offer a wide variety of strut channel manufactured in America by Flex Strut.
What is a Strut Channel?
A strut channel, also known as a channel strut, is a standardized, structural component used to mount, brace, support, and connect lightweight structural loads. These channels are typically made from metal, like galvanized steel or aluminum, and have a “U” or “C” shape. The design of strut channels allows for the easy attachment of fittings, connectors, and other accessories, which can be adjusted along the channel’s length, providing flexibility in installation.
Common Uses of Strut Channels
Strut channels are used in a wide variety of applications, including:
- Electrical and Mechanical Supports: Strut channels are commonly used to mount electrical conduits and mechanical pipes, providing a secure framework that can support these systems across various spans.
- Pipe and Conduit Mounting: They serve as a reliable method for suspending pipes and conduits, particularly in commercial buildings and industrial facilities.
- HVAC Systems: In heating, ventilation, and air conditioning (HVAC) systems, strut channels support ductwork and other components, ensuring stability and ease of maintenance.
- Solar Panel Framing: Strut channels are also used in solar panel installations, where their adaptability allows for precise positioning of panels.
- Industrial Shelving and Racking: They provide a robust framework for industrial shelving and storage solutions, enabling efficient space utilization.
- Custom Applications in DIY Projects: DIY enthusiasts often use strut channels for creating custom furniture, shelving, and other unique projects due to their ease of use and adjustability.
Advantages of Using Strut Channels
- Versatility and Ease of Installation: Strut channels can be quickly installed and adjusted without specialized tools, making them ideal for projects that require flexibility.
- Reusability and Adjustability: The modular design allows for disassembly and reuse in different configurations, reducing waste and cost.
- Compatibility with Various Accessories: A wide range of fittings and accessories can be used with strut channels, expanding their functionality.
- Cost-Effectiveness: While the initial investment may be higher, the long-term savings from the reusability and adaptability of strut channels often outweigh the cost.
Strut Channel Sizes and Types
Strut channels come in various sizes and profiles to suit different applications.
- Common Sizes: The most common strut channel size is 1-5/8" x 1-5/8", but they also come in other dimensions like 1-5/8" x 7/8". The choice of size depends on the load requirements and the specific application.
- Different Profiles: Strut channels are available in different profiles, including slotted, solid, and back-to-back configurations. Slotted channels allow for easier adjustment and positioning of components, while solid channels provide maximum strength.
- Light-Duty, Medium-Duty, and Heavy-Duty Channels: Depending on the application, strut channels are classified as light, medium, or heavy-duty. This classification is based on the channel's thickness and the load it can support.

Load Capacity and Structural Considerations for Strut Channel
The load capacity of a strut channel depends on several factors:
- Material: Steel channels typically hold more weight compared to aluminum, but aluminum is lighter and resistant to corrosion.
- Channel Size: Larger and thicker channels can support heavier loads.
- Support Span: The distance between supports significantly impacts the load capacity. The shorter the span, the more weight the channel can hold.
- Safety Factors: Always consider a safety margin when calculating load capacity to account for unexpected loads or conditions.
Materials & Finishes of Strut Channel
Strut channels can be customized to meet specific needs:
- Powder Coating, Galvanization, and Other Finishes: To enhance durability and resistance to corrosion, strut channels can be powder-coated, hot-dip galvanized, or plated with other protective finishes.
- Custom Cutting and Perforation Services: Some suppliers offer custom cutting and perforation services, allowing you to tailor the strut channels to your specific project requirements.
