How to determine the specification of Wire Mesh?
By several basic concepts: Mesh, Aperture size (w), Wire diameter (d), Pitch (t), Mesh thickness

Learn about Warp and Weft Wire
In wire cloth weaving, wires running lengthwise are known as warp wires, while those running crosswise are weft wires. The high grade steel wires used can meet the most demanding requirement in terms of material thickness, diameter tolerances, yield strength and wire surface.

Wire cloth with square openings is specified by aperture size and wire diameter. The aperture size (w) describes the distance between to neighboring warp or weft wires, measured in the centre of the aperture. The wire diameter (d) given in the specification always refers to the measurement taken before weaving. The weaving process may have a slight effect on the wire diameter.  Pitch (t) consists of the sum of the aperture size and the wire diameter: t = w + d.

Mesh count is calculated upon the number of apertures per English inch (25.4 mm).

Wire cloth with square or right angled apertures should be described using actual aperture size (w) and wire diameter (d).

The open area describes the sum of all apertures as a percentage of the entire surface area.

Mesh thickness is a controlling factor in screen printing. It is based on the wire diameter and the weaving process.  Thickness measurement is carried out prior to tensioning using a sensor, measured pressure 1/8N, on a rigid, flat substrate.  The quoted tolerances correspond to a maximum value across the entire SD mesh output. Within a single roll, fluctuations are significantly less.
