Twilled weave

Twilled mesh gives the smallest apertures for monofilaments as well as a smooth mesh surface, whilst the larger material diameter gives higher levels of mesh stability. To pass through the mesh, particles must negotiate five offset pore levels. This means that even elongated, thin, rod-shaped and filamentary particles are reliably retained.

These meshes are used at fine specifications for fine filtration such as pressure filters in hydraulic steering equipment and fuel filters in critical applications. Coarser specification twilled meshes are used in pressure and vacuum filtration (disks, battery and drum filters) and as a porous medium for fluidised bed applications.

Plain weave

These meshes feature a lightly textured surface and are characterised by extremely high flow rates and minimal loss of pressure.

They are used for alluvial filters and filter candles with increased mechanical loadings.


This stainless steel filter mesh offers high flow rates and advanced dirt removal capabilities.

These meshes are used for oil and fuel systems, mainly where advanced dirt removal capabilities and high flow rates are required, for the protection of steering and injection jets as well as friction bearings.


These meshes are characterised by high flow rates due to increased porosity. They can be compared with smooth weaves, but due to consistent material diameters in both warp and weft directions they are suitable for applications with high mechanical loading.

Typical applications include alluvial filters, filter candles, vacuum filters and tube filters.


These meshes are characterised by high flow rates. They are suitable for increased mechanical loadings and have a lightly textured mesh surface.

Duplex meshes are commonly used in applications such as pressure and vacuum filtration as well as filter candles.

Square weave mesh

In contrast to twilled meshes, the wires in these meshes are woven offset. This results in an open mesh, through which the flow passes in a linear manner. This mesh style is characterised by exceptionally low flow resistance and particularly good backwashing and cleaning properties.

Square weave meshes are used in protective filtration with low differential pressures and for applications including backwashing filters when used with a support mesh.

Important notice to our current and future customers:

G. Bopp + Co. AG (“Bopp”) and even their existing customers have recently noticed that online offerings of products which look similar to those of Bopp and declaring them as “Bopp” products are increasingly being introduced on online purchasing platforms. There is no doubt that these offerings infringe Bopp’s trademarks, violate unfair competition (and other) laws and seriously deceive the market participants.

Bopp have reacted and undertaken respective measures to defend and protect their rights. Considering the enormous number of violators, it seems inevitable that this process will take longer than Bopp desire.

In the meantime, Bopp would like to emphasize the following:
Products manufactured by G. Bopp + Co. AG in Zurich, Switzerland are exclusively available from its subsidiaries in Switzerland, Germany, England, Italy, Sweden, USA, Korea and China and the nominated representations.

G. Bopp + Co. AG are one of the world’s leading producers of precision woven wire meshes providing their high-quality products to market leaders in the high tech, pharmaceutical, chemical, aeronautics, plastic, glass, ceramics, mechanical engineering, paper, environmental technology and even space travel (www.bopp.com).
