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