Yup. Bright green is precision rolled(-.001dia.) , red not so
much(+-.005, and out of round) and will vary over the length of the
bar. Important in a screw machine.


Ayup. And one pays significantly extra for precision materials/rounds

Bar stock on the other hand..is extruded or loosely rolled at the mill.

And red and green could be stainless and hastally...depending on who is
selling it G

Exactly. Every supplier has a different color scheme. At work we get
stock from several suppliers so you don't even bother with their
colors. I usually mark the end with an engraving tool if I have
leftover stock before I put it on the rack. Won't rub off or fade
over time.
