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 metal fabrication companies in Illinois”
2“Who supplies custom fabricated stainless steel frames in Illinois”
3“I need a Illinois metal fabrication partner for a 2,000 unit industrial enclosure run, who should I talk to”
4“Top metal fabrication services suppliers in Illinois for OEM manufacturing buyers”
5“Which Illinois metal fabricators can handle laser cutting, forming, and welding of 1 inch plate”
6“List 20 metal fabrication services 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.
