I would not run steel wire. There are many stranded wire
confightations for low volt wiring. I suspect you only need 2
wires, so simple 18 AWG twisted pair should be more than adequate
for your needs. You can get heavier gauge, but conduit or "smurf
tube" may be better protection of the low volt wiring.

Greetings,

I have previously used small wire for doorbells, intercoms,
security
systems, etc. and have experienced some degree of wire damage at
tenants' hands simply due to the physical strength of the wire.
I
could switch to romex but I don't really want to pay for it and
fear it
might confuse someone into combining a high and low voltage
system.
Where can I get solid ~12 AWG insulated steel wire? I remember
being
able to purchase a 1 mile spool of 12.5 AWG galvanized steel
wire for
electrical fences for under $50. What I want probably weighs
too much
to economically ship off the Internet. Where can I find it
locally at
a reasonable price and if nowhere then perhaps if someone could
refer
me to a cheap Internet sight?

Thank you for your time,
William
