Do not leave copper in direct contact with galvanized steel where moisture is possible. Isolate or replace the support with compatible hardware.

Field verification checklist

Identify whether the line is copper refrigerant, water, med gas, or controls.
Look for moisture/condensation exposure.
Check for existing green/white corrosion marks.
Use approved isolator or compatible clamp.
Coordinate with the trade that owns the pipe.

Ask foreman

There are galvanized straps touching copper lines at [location]. I checked for direct contact and moisture. Do you want compatible clamps/isolators installed and the owning trade notified?

Route options

AMake the field correction only if it is within your assignment and the approved method.

BHold and document the condition if the fix affects support load path, structural steel, seismic restraint, life safety, another trade, or inspection.

CBring the foreman/detailer the location, what you checked, and what decision you need before loading, cover, startup, or rework.

Do not do this

Do not clamp raw copper directly with galvanized sheet metal straps.

Why this matters

Galvanic corrosion can damage copper lines and create leaks that become another trade’s emergency.

Final verification

Use this as field training guidance. Final direction still comes from the foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, structural/seismic detail, and AHJ/code requirements.
