Not something we normally get involved in installing, but, we have a long straight run of galv conduit to install (approx) 60 mtrs. Would this require any sort of expansion joint?

Expansion joints, no.... but you'll need plenty of inspection couplings/boxes though.
Dont bother with inspection couplers or bends etc just get through boxes, you will thank me later when you try to get cables through
Ah, someone at last that knows his conduit!! lol!!
You asked a question but forget to tell us the environment and temp' gradients changes etc ..... if its in the sun you may be surprised how hot the metal can get and not just expansion issues but ambient temp of cables rockets up... generally when you don't have these concerns take all the above advice as no need for expansion allowances
I really like working with galv.
It is much more satisfying to manufacture your own bends, sets etc.
Most of our work is in plantrooms so we use galv trunking, conduit or tray a lot
