Did you use galvanized? Or stainless steel?
I only ask because the galvanizing can be very bad environmentally for the soil. If you need a good source for the welded material - try here:
Welded Wire Mesh
This looks like a woven wire mesh material (something like what is produced here: http://www.bwire.com )- possibly stainless steel?
If this is stainless steel - go to your local scrap yard - this stuff only costs about $.03 on the open marker - offer 10 bucks for a piece, and you should be all...
