I would look for metal fabricators on google maps and start calling around. Some places may be specialty fabricators and won't have what you're looking for, but ask them for a recommendation. A standard steel shop has lots of stock material on hand and can order more.
My go to location for steel beams and fabrication is Smede & Sons in Redford Township. (313) 937-8300
