Some coated products don't list the true gauge before coating.??
I am confused. Wire thickness is specified via it's "guage"; the lower the number the thicker the wire. Your statement saying "17ga before coating19ga after coating" cannot be correct. 17ga wire is 0.0453" thick, 19ga is 0.0359" (per https://precmfgco.com/wp-content/up...Wire-Gauge-AWG-Sizes-and-Properties-Table.png).
Galvanizing with zinc is always under 10 microns, usually 6. A micron is a unit of length equivalent to a millionth of a meter. In short "coating" a wire will not change the thickness of wire to any meaningful degree.
