Low Cost Mesh 75micron/250mesh Standard market grade 75micron/250mesh

Varied apertures – poor product cutDamaged wire due to poor wire drawing techniques

and/or low quality stainless steel – Reduced mesh strength & Limited mesh tension

Close up of wire after it has been drawn. Left picture shows surface defects. Right picture is as supplied by RF.

Mesh defects – Major compromise on

product quality

ISO 9044The above standard allows up to 40 blemishes

per standard roll. (36 M2)

The above standard allows 6 aperture in every 100 to be between 25% and 50% different to the arithmetical aperture size.

Material does not have to lie flat.

Material can be supplied with a film of oil.

Material and wire can show weaving/drawing marks.

The Russell Quality

• Maximum sieving efficiency – Mesh selection based on ‘Aperture & Wire diameter’ rather than ‘Mesh count’

• Sieving accuracy – optimum product cuts, consistently

• Improved mesh life – High precision mesh manufacture

• Reduction in frequency of re-meshing

• Uniform apertures

• No Defects

• High Quality Drawing techniques – maximising wire strength

Micron vs Mesh Count

1 inch

MESH COUNTThe number of apertures which are counted in a row, one behind the other per inch

Mesh Count = 25.4mm

Aperture Size (mm) + Wire Dia (mm)

Aperture size (Micron)The distance between two adjacent warp or weft wires
