Hi John. Welcome to Just Answer.

Are the columns made up of I-beams, installed in a vertical orientation? If so, they should have flanges that you can connect beam clamps to.

You can drive one ground rod, and then route a #6 copper wire from the rod to each column. I would bury the wire between columns, just to discourage theft.

You can install a beam clamp on each column, and then put a screw through lugs that are crimped onto the ends of the wires that run from column to column.

Jason Is the grounding necessary. Would you do it.

If it is just metal columns, with one end in contact with concrete, and the other end in contact with wood, I probably wouldn't bother grounding it.
