Mill Grade Square Mesh

This table is designed to guide you in deciding what mesh type is appropriate for your application. While a specific mesh can have the same number of wires/inch as another, a different wire diameter will alter the aperture as well as the % open area. For instance, one of the tradeoffs between choosing a TBC (Tensile Bolting Cloth) grade over a Market Grade with the same aperture is a greater throughput but at the same time potentially shorter effective screen life.
