Glossary of Terms

The combination of mesh count and wire diameter determines the aperture, the open area and the strength of the mesh. For any mesh, a thicker wire will produce a more robust weave but the aperture and open area will be reduced, giving a slower flow rate to the material passing through. Using a thinner wire the converse will apply.
Warp:
The wires running lengthwise in a mesh.
Weft (or Shute):
The wires running transversely across the mesh width.
Aperture:
The aperture is the size of the openings in the mesh, ie the distance between two adjacent warp or weft wires. As most meshes are square woven, these distances will usually be the same and hence only specified once.
Aperture (in mm) = 
– d
Where ‘M’ = mesh count per mm
And ‘d’ = wire diameter in mm
Mesh Count:
The number of apertures or wires in a linear inch. As most meshes are square woven, they will have the same count in both warp and weft.
Open (or Free) Area:
The proportion of aperture expressed as a percentage of the whole area.
Open area % = 
x 100
Where ‘a’ = aperture in mm
And ‘d’ = wire diameter in mm
Selvedge:
The finished edge formed by looped weft wires at either side of the mesh.
