Can strut channel be used for rooftop support systems?

Yes. Strut channel is suitable for rooftop pipe supports, rooftop conduit supports, rooftop cable tray supports, rooftop HVAC frames and solar roof mounting supports.
Rooftop applications should consider roof membrane protection, non-penetrating support design, wind load, drainage, UV exposure, corrosion resistance and load distribution. Professional rooftop support suppliers commonly use standard 1-5/8 inch channel strut with hot-dipped galvanized or stainless steel metal components.
