Takes two coal and one iron ore to make a steel bar... you've got 60+ smithing, weird that you don't know it... I suggest merching high demand items like rune, coal or lobsters. It's a given that you need 2 coal and 1 iron. I figured that was understood so I didn't bother to mention it. Regardless, you still make a profit. Yes, but you said that you could make double profit... You make a profit, but from what I've seen, it takes 2-3 hours to smelt 1k steel bars, your making 33k per hour, and I'm sure he could do a lot of other things, like merchant. Also, to the guy who said make nats, he's f2p!!! Merchant would be my suggestion. There are lots of good guides here, you'll find some good ones! :
