Mainly because from our perspective we can see.. it's one size all the way around. So it looks to be uniform in material.. which pretty much eliminates fiberglass.. and aluminum might be viable, but at what cost to make huge drawn beams like that? And still doesn't explain why not using more conventional dimensional stuff like tubes.
Well, they do make fiberglass structural shapes like beams, plates and angles that when finished look exactly like primed and painted steel and then can be bolted together to look like that. However you're right it, probably would be faster and cheaper just to have it built in plain ol' steel. Like you said there are some larger but fairly lightweight steel sections that could be selected that have the same appearance as heavier grade steel.
Perhaps there's a part of the ride that one of the sides gets blasted and the insides are exposed which would explain why it looks like that, or if they do indeed move around than that would also be a good reason.
