Quick definition: Dutch weave wire mesh uses unequal warp and weft mesh counts and wire diameters to form a complex filtration path. The square mesh equation 25.4 ÷ mesh − wire diameter does not yield its effective pore size or filtration rating.

How to interpret the reference values
Plain Dutch: alternating warp and weft interlacings with closely packed unequal wire sizes. Twilled Dutch: twill interlacing allows dense weft packing. Reverse Dutch: a reversed warp/weft arrangement commonly used in belt-type filtration. The original reverse-weave catalog section groups reverse plain and reverse twilled together without identifying the weave for each row, so this lookup deliberately does not assign an unverified subtype.
The PDF calls one column “Aperture (µm).” This is a catalog-listed reference number, not the square opening of an ordinary woven square mesh, and the catalog alone does not establish the measurement method, retention efficiency or whether a value is nominal versus absolute filtration rating. For reverse-weave rows, the source does not supply a comparable aperture or kg/m² field, so this tool displays “—” instead of estimating either.
Catalog codes on several reverse-weave rows repeat in the source. To avoid presenting an ambiguous stock code, reverse-weave entries display “—” for the code. Choose the weave, warp/weft counts, both wire diameters, alloy, roll width and length, and agree the test/acceptance method before treating a catalog reference as an order specification.
Example: 165 × 1400 Twilled Dutch
The source catalog lists code SDT1651400, 165 × 1400 warp/weft count, 0.071 × 0.040 mm wire diameter, a 16 µm aperture reference and 0.76 kg/m² catalog weight. This is not a verified 16 µm particle-retention claim, and the actual roll should be evaluated against the agreed drawing and test basis.
FAQ
Can the square mesh calculator be used for Dutch weave?
No. Its simple two-dimensional opening calculation assumes square weave geometry. Dutch weave requires a different structural interpretation and, for filtration performance, suitable measurements.
Can two Dutch weave specifications with the same mesh count have different filtration performance?
Yes. Warp and weft wire diameters, weave construction, production tolerances, finishing and test conditions can change the flow path and performance.
Does a blank aperture mean the reverse Dutch mesh has no filtration performance?
No. It means the original catalog section does not provide a comparable numerical aperture. A measurement or agreed rating test is needed.
