Short of a plasma cutter or a cutting torch, there are a few different saw options. There are sawzall blades for steel, though the cutting will be slow and you'll go through alot of blades. A better option for straight cuts is to get an abrasive cutting blade for your circular saw. If you're making really long cuts in 1/4", for say a skid plate, you may want to find a friend with a torch.
Good luck!
