HOW TO MEASURE WIRE MESH?--GLOSSARY OF TREMS

Aperture(w) space between adjacent parallel wires
Wire diameter(d) diameter of wire before weaving
Mesh count(n) Number of aperture per lineal inch measured from the center of one wire to a point 1 inch distant
Pitch(p) Distance between the centers of two adjacent wires i.e. w+d
WarpWires running lengthwise in the cloth as woven
WeftWires running crosswire in the cloth as woven
Open areaThe fractional open surface area of the wire cloth in follow direction. (applicable for square meshes only)
PorosityThe fractional void volume of the mesh

Wire Diameter

Wire diameter is always checked with a micrometer caliper as shown. Diameters of wires in both directions should be checked. The illustration shows .025 diameter wire.

Mesh Account

Mesh account means how many holes per inch(25.4mm)
0.25mesh-30mesh can be checked with small ruler if you don't have technical tools.
30mesh-500mesh and all Dutch weave mesh need technical tools, please contact with MAISHI if you need help on measuring mesh
