I believe drill-rod is harder than ordinary, cold-rolled steel - I cant give the specs to back that up definitively, but in my 14 yrs of industrial maintenance experience, I believe that to be correct.

I agree if I am right in thinking that "drill-rod" is the material called "silver-steel" in the UK. This is an alloy capable of being hardened and tempered to make cutting-tools, spindles etc, but is pretty tough to machine even in its annealed state. Cold-rolled mild-steel in turn, is tougher than hot-rolled m.s. but I don't know if it is any stronger. That would depend on the specific alloy rather than process.

Is cold rolled harder than hot rolled steel?
They are two different things. Zinc plated means it's coated in zinc. Cold rolled means it's "smashed" into shape without added heat. So you could have something that's cold rolled AND zinc plated!

Can you solder cold rolled steel?
I have found through experience that hot rolled steel will take 95/5% solder, and that cold rolled will not solder, reason is the cold rolled steel molecules are arranged differently that the hot roll, they are so to speak pushed into the final dimension with extreme pressure this also causes a so called hardened tempered surface on the cold roll steel that has to be annealed so that it can be drilled. cut or soldered.
