Steel of any sort is about the worst possible choice for a primary 
conductor.  Yes, the rolls of steel shipping strap material look tempting, 
but the resistance of steel is very high.  Use only copper.  1/4" copper 
refrigeration tubing is common, inexpensive, easy to form, easy to tap, 
easy to solder, and performs very well - I recommend it.

I was toying with the idea of making my primary out of a strip of
metal.  Seems like it may be easier to construct a primary coil from a strip.

Is spring steel ok for this or is copper the way to go?  Or are there any
other suggestions for material?

The other question is how wide and thick is recommended?
