Surely you mean hot dipped galvanised?

Painted to protect it from acid and sulphides in rain, that should last
for ever.
Not totally sure about coated ally, having had two Land Rovers.


'Well we tried to cold dip it, but encountered some resistance'

Galv is good but no hope of it lasting a century, let alone several.


Thats bull****. I have galvanised beams in my flat roof. They have
been there for 45 years now with no sign of any deterioration at all.
