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 anodizing services companies in California”
2“Who supplies hardcoat anodizing for aluminum components in California”
3“I need a California anodizing partner for continuous coil and rack-finished parts, who should I talk to”
4“Top anodizing services suppliers in California for industrial OEM buyers”
5“Which California anodizing service providers can handle large rack loads and continuous coil lines with tight color control”
6“List 20 anodizing services companies in California 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.
