galvanised steel

[the pict]

Whats best to get a good earth grind it off and re-paint or bolt to the surface, is galvy a good conductor ? trying to weld it would suggest it aint

My limited understanding always led to me believe in many instances, zinc dips were actually done to improve the conductivity of the surface...surely, as mentioned previously numerous times, the need to grind and re-coat is somewhat redundant. time could be better spent drinking a cup of tea?

Nope, Hot Dip Zinc plating is purely for it's corrosion protection properties of mild steel, and some other metals.

And by providing good corrosion protection, it helps to ensure good continuity of the bond in the future. An uncoated mild steel surface left after grinding is totally dependant on the zinc-rich paint to prevent it rusting, which would lead to failure of the connection. Paint is surely second-best to galvanising?

think i would drill & tap then apply anti-oxidising paste to finished bond
