Strut channels are structural supports, used mainly in the construction industry. Typically made of stainless steel, a strut channel is three-sided, with the side panels having inward-facing lips for added strength and support. A slotted channel has holes or slots to the top of the strut for more attachment flexibility. We also carry Superstrut brand struts in many sizes and styles. Zoro has a wide selection of strut channel accessories, flat washers, and conduit clamps & hangers too.
