Strut channels—also known as channel struts or framing channels—are essential components in modern construction, electrical installations, and mechanical support systems. They provide a versatile framework for mounting, bracing, or supporting everything from conduit and cable trays to HVAC units and solar panel racks. But not all strut channels are the same. Differences in shape, slot design, material, and surface finish can significantly affect performance, load capacity, and corrosion resistance. Choosing the right type ensures a safe, efficient, and cost-effective installation. We will provide you with information on the main types of channel steel currently available on the market and help you understand when and why to choose each type.
