ansi sheet or plate
i think this is the best place to post this. let me know if this should go into another forum. i was asked if there was a standard that stated material up to a certain thickness is call "sheet" and anything above that thickness is called "plate". i can not recall if there is a standard for this or not. is this a company thing?

don't worry about people stealing your ideas. if your ideas are any good, you'll have to ram them down people's throats.

i think it is a company thing. in college, i heard it said that caterpillar considered anything up to 3" sheet, while boeing considered anything over 1/8" plate.
your thicknesses may vary.
"wildfires are dangerous, hard to control, and economically catastrophic."
"fixed in the next release" should replace "product first" as the ptc slogan.

the asm glossary of terms reports the following:
plate
a flat-rolled metal product of some minimum thickness and width arbitrarily dependent on the type of metal. plate thicknesses commonly range from 6 to 300 mm (0.25 to 12 in.); widths from 200 to 2000 mm (8 to 80 in.).
sheet
a flat-rolled metal product of some maximum thickness and minimum width arbitrarily dependent on the type of metal. it has a width-to-thickness ratio greater than about 50. generally, such flat products under 6.5 mm (1/4 in.) thick are called sheets, and those 6.5 mm (1/4 in.) thick and over are called plates.
