Can SS Mesh Be Found at Retail Stores?

[nettles4349]

Are there any retail stores where I could buy stainless steel mesh for RBAs? I've heard that it has to be "food grade" or something like that so I'm pretty sure I can't just go to Home Depot or Lowes and get any old SS mesh, but are there any retail stores that sell SS mesh of various porousness (like #300 mesh, #400, #450, etc.)?

That's a great question, been wondering myself!
