What Is Knitted Wire Mesh?

Knitted mesh, as its name implies, is a metal wire or plastic strand knitted into an interlocking looped mesh structure, the same way as stockings and should not be confused with woven mesh, which is the form of rectangular openings of parallel wires. The knitted mesh has a flexibility not possessed by the woven mesh, due to the loops being able to move relative to each other thereby giving a two-way stretch. This flexibility gives knitted mesh a unique advantage for many industrial uses.

Forms Of Knitted Wire Mesh

Knitted mesh is produced in a long, flat, double thickness from 0″ to 40″ seamless width on a cylindrical machine. The output is a continuous stocking of mesh, which is pulled through the knitter by take-up rollers. It can be used directly in this flattened form as an insulation covering or it can be further processed into several other basic forms. Flattened mesh is sometimes run through corrugating rolls to create crimped mesh. In this form the corrugations act like springs for resiliency and give mesh thickness.

Materials

The usual materials are metals, aluminium, monel, stainless steel, nickel, copper, galvanised steel and plastics, polypropylene and nylon.

Mesh Sizes

The most popular meshes are between 3 and 8 openings to the linear inch. Almost any material that can be drawn into a filament smaller than 0.35mm for metals (plastics from thicker filaments) can be knitted, providing that it has been suitably drawn.

Properties Of Knitted Wire Mesh

Knitted mesh has both a large surface area of wire and a high percentage of free space. The open space in a mesh can be controlled from 50 to 98% since it is possible to knit meshes of a wide range of opening sizes regardless of wire diameter. These features become important in uses such as filtration, where flow resistance is critical. Another feature of knitted mesh is its inherent resiliency. Every loop of the knitted structure becomes a small spring when subjected to tensile or compressive stress and when not distorted too drastically, will immediately resume its original form upon relief. Even when the mesh is compressed into a special shape, a high degree of resiliency is retained. This can be controlled by varying sizes of opening wire diameter and material, crimping and pressure used to create the part. Compressed, layered, calendered and wound mesh units all have the common property of presenting a “Tortuous Path” to the flow of liquids or gases through them. this is used in filtration, diffusion, distillation and flame arrestors.

Our Ethos

Our policy is to use only “first class” materials and whether you need just a few square feet, or 100 rolls, we are pleased to supply.

One Off Jobs

We also manufacture products from the above material and can cater for one-off jobs, small, medium runs as well as large quantity runs.

Our Speciality

We specialise in all forms of wiremesh, e.g. woven wire, knitted wire, welded wire, perforated metals and expanded metal.
