Woven wire cloth – General

Aperture width w is the distance between two adjacent warp or weft wires, measured in the projected plane at the mid-positions.

Wire diameter d is the diameter of the wire in the woven cloth. (The wire diameter may be altered slightly during the weaving process.)

Pitch p is the distance between the middle point of two adjacent wires or the sum of the aperture width w and the wire diameter d.

Warp: All wires running lengthwise of the cloth as woven.

Weft: All wires running across the cloth as woven.

The number of apertures per unit length, n is the number of apertures which are counted in a row one behind the other for a given unit length. The unit length may be 1 cm, 1 dm, Inch or any other unit of length. (The number of apertures with a length of 25.4 mm is designated as "Mesh")

Mesh = number of apertures per English inch = 25.4 : p

The percentage of the area of all the apertures in the total screening surface or the ratio of square of the nominal aperture width w and the square of the nominal pitch (= w+d), rounded to a full percentage value: Ao = 100 (w : p)²

Type of weave is the way in which the warp and weft wires cross each other.
