Square mesh – Wire cloth having the same number of wires in both the warp and weft.

Wire cloth – A general term for material woven from metallic wires.

Mesh – The number of openings per lineal inch.

SWG – Standard wire gauge

Aperture – The distance between two adjacent wires

Diameter – The thickness of the wire before weaving

Pitch – The distance between the middle point of two adjacent wires or the sum of the aperture width and the wire diameter

open area – The ratio of area of the aperture to the area of the mesh

Warp – All wires running lengthwise of the cloth as woven

Weft – All wires running across the cloth as woven

Tensile strength – The ratio of maximum load to original load to original cross-sectional area.

Coarse mesh – Openings that range from about the size of a pencil lead (2 mm) and downward to the size of a medium human hair (0.12 mm)

Fine mesh – Openings that range from about the size of a medium human hair (0.13 mm) and downward to the size of a large bacteria (0.02 mm)

Type of weave – Way in which the warp and weft wires cross each other.

Plain weave – Wire cloth in which the warp wires and weft wires pass over one and under one wire in both directions.

Dutch weave – Wire mesh or wire cloth with wrap wires larger than the weft wires.

Twill weave – Wire cloth in which the wrap wires and weft wires pass over two wires in both directions.

Twill dutch weave – Similar to plain dutch weave, except that the weave pattern is twill, that is a double layer of weft wires.

Reverse dutch weave – The same weave as plain dutch, except that the warp and weft wires are reversed, that is, the warp wires have a smaller diameter than the weft wires.

Filter cloth – Wire mesh used for filtering and straining

Filter cake – Material that is retained on the filter cloth during processing.

Cloth thickness – Overall thickness of the filter cloth, nominally estimated by adding the wrap wire diameter plus two times the weft wire diameter.

Micron – Common filtration reference to a particle size, properly defined as a micrometer.

Shielding cloth – Wire cloth (wire mesh) used for shielding radio frequency equipment and rooms.
