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 suppliers of tanks and pressure vessels in Indiana”
2“Who supplies ASME-certified stainless steel process pressure vessels in Indiana”
3“I need a Indiana tank and pressure vessel partner for a custom chemical processing line, who should I talk to”
4“Top tanks and pressure vessels suppliers in Indiana for chemical plant engineering buyers”
5“Which Indiana tank and pressure vessel fabricators can handle large-diameter, high-pressure reactor vessels”
6“List 20 tanks and pressure vessels companies in Indiana 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.
