Are there any situations where you would not bond structural steelwork. I have some vague recollection that there may be, but can’t think what they might be.
It is worth remembering that in most circumstances, that structural metalwork will end up connected to the main earthing terminal, even without any deliberate bonding connection.
Metal electric conduit should be earthed, and is liable to be in contact with building steel.
Class one light fittings are often in contact with metal roofing or supports.
Circulating pumps should be earthed and are likely to be in contact with structural steel, via the pipes.
Electric water heaters also.
Most metal building frames are in good contact with the general mass of earth via the footings or foundations.
