Not woven. Here we call it welded wire. All the wire is just to sides (hope this makes sense) one side is vertical, other is horizontal, tack or press welded where they meet. Mine is not stainless but suppose it could beThis 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 set. Metal scrap yards are the best for stuff like this!
