Another possibility is to use a cut-off saw with a Steel Demon blade. I have an old battery-operated Makita 7.25" saw that I use to cut just about anything - within its range of course. I have cut 2" square tubing for a 2" x 72" grinder I am building. Takes about 25 seconds to make one cut using this saw. It's pretty amazing. I had an old Grizzly bandsaw and that was taking over 3 minutes to make a similar cut.
