What Instruments are used to Identify Stainless Steel Wire and Mesh?

Stainless Steel Wire Diameter

Vernier calliperMeasures the stainless steel wire diameter;

- measurement resolution of 0.01mm

- measurement accuracy of ±0.03mm

- measurement range of 150mm

MicrometerMeasures stainless steel wire diameters

preferable for diameters less than 1mm;

- typically has a 10 times better measurement resolution of 0.001mm

- measurement accuracy of ±0.004mm

- measurement range of 25mm

Stainless Steel Woven MeshTwo measurements are necessary to define the

mesh, all other parameters can be calculated

from these two;

- Mesh

- Wire Diameter

Ruler ‘0’ is lined

up along an

inside wire

There are 4 stainless steel wires per inch

The mesh is 4 mesh by 1.60mm wire diameter

The naked eye can count the wires per

inch of meshes up to about 10 but more

difficult for meshes above this

Stainless Steel Woven Mesh

Defined by following Parameters

Mesh – the number of openings per lineal inch

(2.54mm) refer to previous slide

Aperture – the distance between two adjacent

wires (opening)

Wire Diameter – the thickness of the wire before

weaving

Pitch – the centre to centre distance between two

adjacent wires (= aperture + wire diameter)

% Open Area – the ratio of the aperture area to the

total mesh area (calculated from the aperture and

the wire diameter)

Counting GlassGreatly magnifies the view and is used for fine mesh

½ inch- count wires x 2

¼ inch- count wires x 4
