I was leafing through the catalog from one of my suppliers when lo-and-behold there are 2-3 pages of different meshes! I thought about offering these for sale myself, but figured it would just be easier to give you the link to their website. Here's a sampling:
They also have expanded metal mesh (similar to gutter guard) and various plastic meshes in black, brown, white, chrome, brass, and copper. So far I've only found the woven metal grills on the website, the expanded metal and plastics might just be in the printed catalog.
Be forewarned: The woven metal grill material is not cheap! Prices seem to run from $80-310 per sheet of this stuff, depending on the mesh, with sheets being 3' x 4'.
That being said, here's the link:
Outwater Plastics Scroll all the way down to the bottom and you will see the link for "woven wire grills". If anyone decides to try this out, for gods sake PLEASE POST YOUR AFTER PICS FOR US!!
