Okay, this is a technical question then: this would be "manufacturing" the steel as opposed to "fabricating" it, correct? Or is there another term?
I just said "make" in the article, because I wasn't sure. Nice simple word, but a little vague...
The word is "make," correct.
Fabrication is done by thousands (used to be lots more...) metal-benders including those which supply Maytag, GE, etc., etc.
Generally, the automakers bend their own metal for fenders, doors, etc.
