We have a Lot of Pole buildings in our area. As some contain livestock ect we require the metal siding to be bonded. The usual Method is when the # 6 is run to the ground rod a Lug is fastened to the siding and that wire run thur the lug on the way to the grounding Electroid.
We do not require each individual sheet of siding to get a connection. We've found that to work quite well. If you want to comment on this renosteinke please make it a Polite and Possibly Constructive comment. I;ve been in the Trade over 45 yrs & formally carried Masters licenses in nine states I feel I;ve earned that!!
Thank you
