Is galvanized spiral duct okay for natatorium or chlorine pool air

3rd YearHand Tools, Fasteners & HardwareStop and get direction

Chlorine/humid pool air can destroy the wrong metal fast. Stop and verify the specified corrosion-resistant material before more work is covered.

Plain-English answer

A natatorium is not normal office air. Warm, humid, chemically treated air can attack galvanized coating and seams quickly.

Document the corrosion, check the material spec, and replace or reroute with the project-approved corrosion-resistant duct material, fasteners, sealant, and hangers. This is a spec/material issue, not a cosmetic cleanup.

Ask Foreman

The galvanized spiral at [pool/location] is already corroding in chlorine/humid air. I documented the seams and checked the material concern. Do you want this held for specified corrosion-resistant material?

Verify before acting

Use this as training guidance. Foreman direction, approved drawings, project specs, manufacturer instructions, employer safety policy, and AHJ/code requirements always control the final answer.
