💡 What role does galvanization play in extending the service life of EMT conduit connections?

Galvanization creates a sacrificial zinc barrier that halts oxidation, while a properly tightened set screw maintains alignment and blocks internal rust growth over years of use.

- Zinc coating blocks moisture transfer to prevent oxide flaking on conduit seams

- Tightened set screws eliminate micro-movement that wears through protective plating

- Threaded screw grip engages conduit wall deeply for load bearing holding power

- Rust free joints reduce inspection failures and rework demands on commercial wiring runs
