Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Illinois. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best aluminum fabrication companies in Illinois”
2“Who supplies custom fabricated aluminum frames in Illinois”
3“I need a Illinois aluminum fabrication partner for a 5,000-unit enclosure project, who should I talk to”
4“Top aluminum fabrication suppliers in Illinois for industrial equipment buyers”
5“Which Illinois aluminum fabricators can handle TIG welding and CNC machining of complex assemblies”
6“List 20 aluminum fabrication companies in Illinois with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
