Exposed Copper Conductor

[timm333]

Is it Ok to run bare copper grounding conductor on steel structure and support it by copper clips? I heard that the contact of copper with steel should be avoided, but if we run exposed/bare copper conductor on steel structure, then copper will touch the steel. will it be Ok? Thanks for help!

Unless it is very wet there will not be a problem and the steel would be the anode in that combination and would be the metal that corrodes.
