RUSSELL FINEX MESH
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
