Satoshi mesh? where can i get it?

Im trying to find out where i can get some of the mesh metal that is for the satoshi grille mod. Whether its the mesh or the one that has just the parallel lines. I know that you can get them from Homertaco, but i didnt know if you could get it at a hardware store or a metal shop or something.

 

Some people purchase it at lowes or homedepot. It's called door mesh I believe. Last time I looked though I only found ones with fancy designs haven't checked since. Hope this helps
