In the diverse landscape of the Australian industry, stainless steel woven mesh stands out as a key player. Prized for its high tensile strength, corrosion-resistant nature, and customisable apertures, it’s a material that wears many hats. We’re going to dive into the ins and outs of this industrial essential, covering everything from basic facts to micron measurements.

Mesh is most commonly used as a filter medium. It is used to separate material that is over sized while allowing the material that is undersized to pass through. Different processes require different sizes of material and screening these materials improves the quality.
Woven Mesh has more flexibility than welded mesh. It is often used in dynamic application. Woven Mesh can hold its shape during vibration and impact meaning it has a long performance life with limited maintenance.
In some cases, mesh can be altered to improve its shape-holding ability. This includes “crimping” a wire to provide additional strength to the mesh.
These are the terms that are historically used to describe woven mesh. They are:
At SSWM we can take your Mesh count and SWG and we can supply you with a mesh that meets your specification
Micron is a measurement of the Aperture. A micron is 1/ of a millimetre so a mesh that is 100 micron has an aperture of 0.1mm. It is difficult to compare Microns and mesh counts because different woven meshes have different wire diameters.
We can supply a mesh with a wire diameter of 0.025mm and an aperture of 0.026mm. As a comparison, a human hair can be as small as 0.016mm, so our mesh is small.
This mesh is often used in Scientific labs at universities and research centres in the development of new processes. Because this mesh is so fine, it takes hours for the weaving machine to make this material. This mesh has 500 openings per inch, uses a 50 SWG wire and has an open area of 26%.
Because Stainless Steel Woven Mesh is woven, it can be easily rolled and wrapped. In most cases it can be sent via a courier when the weight is under 32Kgs and the width is less than 900mm.
With over 380 specifications in mesh sizes, our technical sales team are able to work with your specifications, including Mesh Count and SWG, to ensure you find the most appropriate solution for your project requirements.

Mesh Count is the number of openings or apertures (Figure 1. O) which can be counted per every linear inch of wire mesh. This is typically designated for both directions of the mesh. Therefore, a wire mesh which has ten openings per inch as measured across both its width and length would be designated a 10 x 10 mesh or Number 10 mesh.
An Off-Count Mesh would describe a wire mesh which has a different number of openings per inch in one direction than the other. Thus, a mesh with ten opening per inch measured in the length direction and seventeen openings per inch measured across its width would be designated a 10 x 17 mesh.
Pitch (Figure 1. M) is the sum of the aperture or opening size (Figure 1. O) and the wire’s diameter or gauge size (Figure 1. D). Details concerning wire gauges and the wire sizes IWM offers can be found in the Technical section concerning Wire Sizes.
The Warp Wire in wire mesh is the wire running parallel to direction of the wire mesh length or its roll length. The Weft or Shute Wire runs parallel to the width of the wire mesh or the roll’s width.
Weave Types
There are several different general weave types of wire mesh. Twill Weaves refer to woven mesh which has two or more warp wires passing over and under two or more weft wires. This weaving method is typically used for wire mesh used for filtration media. Crimp Mesh refers to wire mesh which has been pre-crimped prior to the final weaving process. Such styles include an Intermediate Crimp mesh where the wire is crimped at each aperture of the mesh, typically in both directions.
A Locking Crimp mesh utilizes a crimp on its wires to interlock both with warp and weft wires. This type of mesh is typically utilized for applications requiring very rigid mesh.
By far the most common type of mesh weave is a Plain Weave or plain crimp wire mesh, which is the weave type IWM predominately offers. A plain weave mesh is where the warp wires and weft wires weave over and under each individual wire strand in each direction. This is depicted in Figure 2.
Additionally, IWM offers a Lockstitch Weave. Similar to a plain weave, the weft wires and warp wires are woven over and under one another. However, a lockstitch is achieved when placing two warp wires closer together when setting up the comb or reed, which separates the warp wires. These lockstitches can be positioned along the width of the mesh roll to prevent the fraying of edges when trimming or slitting the mesh to narrower widths.
Edge Finish
An edge finish is typically designated for a wire mesh if its not a raw edge. A Raw Edge represents a mesh with exposed weft wires which are a result of a rapier (shutterless) loom. Finished edges can be achieved by tucking or looping the weft wires to achieve a finished edge. A Tucked Edge refers to the exposed weft wire being tucked back around the edge warp wires so that the end of the weft wire is no longer exposed. A Selvage Edge or looped edge provides a finished edge for the wire mesh by continuously weaving the weft wire so that there is no exposed wire ends along the length of the roll of mesh. IWM offers both finished and unfinished edges for its wire mesh.
Space Cloth in the context of wire mesh represents mesh which is specified by its opening size rather than its mesh count. Wire mesh may be designated by its percent of open area which can be calculated as follows when its mesh count and wire diameters are the same across its width and length.
