woven wire mesh

Stainless steel woven wire mesh comes in a wide variety of specifications providing a range of mechanical properties. Coarser weaves woven from heavier wire diameters provide useful mechanical strength, while finer weaves are useful as filtration and screening due to their smaller aperture.

Woven Mesh Terminology

Mesh – The number of openings per lineal inch (25.4mm)

SWG – Standard wire gauge

Aperture – The distance between two adjacent wires (opening)

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 the area of the aperture to the area of the mesh expressed in percentage terms

Warp – All wires running lengthwise of the cloth as woven

Weft –All wires running across the cloth as woven
