Ground Bar Attached to Building Column Steel

[faresos]

Hello,

How you can attach a copper ground bar (2" X1/4") into building column steel without drilling or shot pins? Is there any approved way of doing this? Thanks,

I have also used beam clamps.

Are you trying to bond the plate to the steel by mounting it? We use a stud welder to weld studs directly to the steel.
