Our Oval Perforated Aluminum is sold in 12"x24" pieces. It is 0.030 thick. The little oval holes are about 1/4" wide. This perforated aluminum is fairly rigid, but can be bent or curved.
Our Stainless Steel Mesh is also sold in 12"x24" pieces. The diameter of the stainless wire is 0.032". This mesh is a little bit more flexible than our perforated aluminum.
Our Perforated Aluminum and Stainless Mesh works great for custom speaker grilles and vents.
Both the Oval Perforated Aluminum and Stainless Mesh have an open area greater than 50%. This will allow plenty of sound or air to pass through when being used as a grille or vent.
