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 stainless steel fabrication companies in Illinois”
2“Who supplies custom stainless steel process tanks with welded fittings in Illinois”
3“I need a Illinois stainless steel fabrication partner for a short-run sanitary equipment build, who should I talk to”
4“Top stainless steel fabrication suppliers in Illinois for food and beverage plant engineering buyers”
5“Which Illinois stainless steel fabricators can handle TIG welding of thin-gauge stainless assemblies”
6“List 20 stainless steel 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.
