Micronic Mesh (often called micron mesh) is typically used for liquid filtration applications due to the extremely small openings (measured in microns) in the weave and can have greater strength and durability vs. square weave wire mesh.
There are 2 main types of weave – Dutch and Twilled Dutch with the most common variations listed below. Micron retention size, i.e., what the mesh is intended to trap, is the primary parameter needed to determine the correct weave and size. Gerard Daniel is a manufacturer of micron wire mesh offering the most common weaves in ratings from 15 to 200 microns, with 100 microns being the most common, although we also make micron wire mesh to less than 10 microns for filtration OEMs.

Gerard Daniel is a leading global micron-wire-mesh manufacturer with over 70 years of expertise. We carry a wide range of micronic wire mesh in stock from multiple stocking warehouses in North America, including plain dutch weave mesh, reverse dutch weave, twilled dutch weave, reverse dutch twilled weave, and broad mesh types. Many types are available to cut to size for same-day shipping.
Most micronic mesh sizes in stock are 48” wide by hundreds of feet long; other sizes are available on request. We can slit rolls down to 1/4” usually within a few days. We also carry DFARS stock in standard stainless steel alloys. We can laser-cut in small quantities to any shape within a week depending on material availability, and we can stamp high volume custom shapes for micron mesh filter elements pending tooling lead time.
And if we don’t have exactly what you need, we can weave custom micron wire mesh screen to your specifications.
Quality second to none
Since we use millions of square feet of our own wire mesh in the filters and separation products that we manufacture at our own factories, we know about good quality micron wire mesh. Whether we source your mesh or weave it ourselves, you can rest assured you’ll get the highest repeatable performance in micron mesh from our warehouse.
Like plain square weave, the wire in dutch weave is interwoven but the warp wires are thicker than the shute wires. These are arranged very close together to form a zero-mesh structure. This generates a weave that has high inherent stability with a relatively small mesh size. Dutch weave has excellent filtration qualities and can be easily cleaned of filtrate deposits and residual dirt.

“Reverse” describes the fact that the warp wires of this weave are relatively thin and the shute wires are thick – in other words, the exact opposite of the standard dutch weaves. The reverse dutch design, sometimes referred to as “Microdur”, produces precisely defined pore openings that run under an angle to the surface of the mesh. The high number of warp wires increases the active filtration cross section of the mesh.
As with Dutch weave, the shute wires of twilled dutch weave (TDW) are arranged as close together as possible. However, this weave has double the number of shute wires than plain dutch weave. A very small aperture is formed by three shute wires which cross in different directions and, together with the warp wires, create a channel that is open on two sides. The structure of this tight weave provides high filtration accuracy. Another variation is Open Twill Dutch Weave Wire Mesh where fewer shute wires are used to influence the filtration rate.

An important version of the reverse dutch weave is the reverse dutch twilled weave. With this weave, the warp wires are also relatively thin – as in the case of the normal reverse dutch weave. The difference is the twilled weave pattern of the shute wires. This means that the warp wires are not as heavily deformed and physically stressed as in the case of plain weaves. The strength of this weave design is its suitability for applications that are subject to high levels of mechanical stress.
To optimize the filtration capacity of the broad weave mesh cloth, the shute wires of the broad mesh twilled weave are arranged loosely instead of being close to each other. This means that the retention accuracy is lower than that of a classic twilled weave. Nevertheless, the accuracy is sufficient for the requirements of most applications. The surface of the BMT cloth is smooth on both sides, meaning that the filter can be easily cleaned.
