Mesh ,Mesh count

The terms, “mesh” and “mesh count”, are often used interchangeably and represent one of the most important concepts in the industry. Both “mesh” and “mesh count” refer to the number of openings per linear inch – a critical component when specifying wire mesh. To determine mesh or mesh count, start from the center of one wire and count the number of openings to a point exactly one linear inch away. For example, No. 4 mesh (or 4 x 4 mesh) indicates that, in one linear inch, there are four openings. Likewise, a No. 20 mesh (or 20 x 20 mesh) indicates that in one linear inch, there are twenty (20) openings.
