In this video, we take a close look at hot-dipped galvanized metal strut channels and how they perform in electrical and mechanical support systems. You'll see a detailed walkthrough of the manufacturing process, from raw material selection to standardized rolling, plus a demonstration of key strength and corrosion tests. We also compare slotted, round-hole, and solid channel options, explain load grades, and show real installation examples for HVAC, solar, and seismic bracing. Ideal for engineers and buyers who want practical, standards-based insights before specifying structural support materials.
