It certainly doesn't deserve bottom tier at all. The pokemon there are truly terrible stuff like Liepard and Castform that really should not be sent into battle. Ever.
Steelix takes physical hits better than any pokemon in the game and has a ton of resistances too allowing it to comfortably get off a Curse boost. Speed is also largely irrelevant with Defence that large.
The only drawback is that you're stuck with an Onix until Chargestone Cave and a Metal Coat, bearing in mind that Onix hits about as hard as Snivy.
Then again, you can just hold off capturing Onix until you get the Metal Coat, get one in Relic Passage(where they are lvl 29ish), and evolve it immediately.
In fact, with the above method I think Steelix could go as high as Upper-Middle.
