Yes Rob, here superstructure was something very new then but now from that has come the modern day metals used in so many ships now.
It was explained to me as a composite metal using steel and aluminumn
Not my field so have no idea if that is correct, but I was told it reduces weight and does not corrode as much as the old metals did.
in my opinion it would corrode more , dissimilar metals , there was a transition joint to stop this ,
Lithgow's f Port Glasgow,built at least two ships with an aluminium structure in the early sixties.
I remember walking through theaccommodation,as you moved from steel to aluminium it was a strange experience.

Any steel to aluminium joint required an inert material between the two different materials and the joint was often formed using rivets. We had to use yellow chromate primer for any aluminium parts of the accommodation on board e.g. alleyway doors etc.
