Frequently Asked Questions

What is a metal framing channel?  

A metal framing channel, also called strut channel, is a piece of metal with a C-shaped or U-shaped profile, typically made of cold-formed steel. Steel strut channel may also have small, regularly spaced holes called perforations, which allow bracket connections and fittings to be bolted on instead of welded. Companies use metal framing channel to create supports for pipes, electrical conduit, HVAC runs, mechanical equipment, and other systems in commercial and industrial buildings.

What sizes are available?  

G-STRUT® metal framing channel is available in a standard width of 1 5/8” and standard lengths of 10’ and 20’, as well as custom cuts of nearly any length. Depth options range from 13/16” to 3 ¼ “. See the full specifications in our G-STRUT® Catalog.  

What finishes are available?  

G-STRUT® metal framing channel offers a variety of finishes to match the environmental demands of your project. Pre-galvanized strut is a popular option for corrosion resistance, or choose from hot-dipped galvanized, electrogalvanized, galvannealed, aluminum, plain, yellow zinc, PVC coated, powder coat, or stainless steel strut channel. Custom coating colors are also available.

Is G-STRUT® compatible with other brands?  

Yes. G-STRUT® channel conforms to industry standard dimensions and ASTM specifications, making it compatible with other brands of metal framing channel. This allows contractors to incorporate existing framing systems or parts as required and maintains consistency in materials and performance throughout the project.

Why choose manufactured-to-length?  

While G-STRUT® channel is available in standard cuts of 10’ and 20’, manufactured-to-length strut offers clean, consistent shear cuts to your specifications. Pre-cut, labeled bundles allow installation to begin right away, decreasing downtime, labor costs, and measurement errors.
