If Hulk can beat a Demi- God , he'll make short work out of Galvatron. Seriously Galvatron's only hope is that canon of his. Other than that, Hulk should rip him apart..
If he goes into an all out brawl, eventually Hulk will become strong enough to actually damage him.
Galvatron is near indestructable as he was designed by Unicron...he's much, much tougher than any standard transformer.
