Another point on Bob's "inspector" comment. I tend to agree with what he said. I too would fight this if an inspector told me I would have to bond a beam in this situation. As I wrote in another topic there are those that believe that the NEC says you have to bond any and all metal period. It does not. As I stated I was at a grounding and bonding class where the "Instructor" (term used lightly) pointed out that single steel support beams, lally columns, oil tanks, one foot sections of copper pipe stubbed out to bathroom fixtures from plastic pipping systems etc must be bonded. Pretty obvious as to why there is so much confusion. People tend to take everything they hear as gospel. I don't.
