We offer an extensive range of specialist knitted wire mesh products that will satisfy the safety critical needs of many defence applications. The special challenges posed by a variety of demanding military applications require high performance materials that are lightweight and able to perform in harsh environments.
The flexibility (ability to be bent without breaking) and malleability (the ability to withstand plastic deformation without fracture) of our products can be designed according to customer needs. Through a careful selection of materials, mesh structure, and tooling design, we can produce mesh components in an almost limitless range of shapes including sheets (blankets), highly flexible hollow mesh tubes, and 3-dimensional rigid structures such as prisms, cubes, spheres and doughnuts, etc.
Resilience can be defined as the ability of a material to absorb energy when deformed and to release that energy on unloading. The feature is particularly beneficial in applications such as seals (often incorporating resilient cores), gaskets and vibration isolators for use in both high and low temperature environments. Our engineers can work with customers to select the materials and manufacturing methods required to configure a product that will perform to the most exacting specifications.
Knitted mesh is made of wire, comprising continuous lengths of filament of almost any material type, formed into interlocking loops. This unique structure produces a material that, whilst being highly flexible, has the tensile strength characteristics of the component filament material. Applications include very fine flexible mesh nets such as those used in animal enclosures that can withstand snow loading of >250kg per m2.
Knitted mesh is used to form an enclosure that acts as Faraday Cage to block electromagnetic fields. This phenomenon is used to screen (protect) sensitive electronic equipment from external radio frequency interference (RFI) and enhance electromagnetic compatibility (EMC). Faraday Cages are also used to enclose devices that produce RFI, such as radio transmitters, to prevent their radio waves from interfering with nearby electronic equipment. These knitted mesh screens can be produced from a wide range of materials including tin-plated copper or copper-plated steel and formed as cooling vents, flexible cable jointing ‘bandages’, and resilient joint seals with elastomer cores for inspection hatches or doors and windows, etc.
Materials can be selected and processed, in any of a huge number of possible variants, to produce knitted mesh components that will withstand the conditions experienced in the most arduous of operational environments. Corrosion resistance and fatigue tests at up to 1,000°C can be conducted on-site with products typically being used in aerospace, automotive, refractory, cryogenic and marine environments.
A feature of knitted wire mesh is its ability to conduct an electric current. The specific conductance and heat retention and dissipation characteristics, together with the type of wire and its cross-sectional area, are key selection and design criteria. The wire can be insulated by a variety of materials with the most common uses being in heating and security applications.
Being self-extinguishing, our products are characterised by their flame resistance, shock resistance and low outgassing. All of our metal meshes are inherently safe.
Our knitted wire mesh is ideally suited for Electromagnetic Compatibility (EMC) and Radio Frequency Interference (RFI) and other shielding applications used in guided munitions, antenna systems and other electronic applications. In addition, the products are used for venting and filtration in the engine air intakes of military vehicles and vessels.
Other applications include the sealing of back-shells and connectors in aviation electrical systems, and sound and vibration dampening. Whether air, ground or sea, KnitMesh products help our defence forces keep us safe.

Modern telecommunications and electronic devices require protection against radio frequency interference (RFI) and electromagnetic interference (EMI); our knitted wire mesh products help to guarantee the EMC integrity of all sorts of military equipment.
KnitMesh Technologies supply EMC shielding tape as a Pan Mesh approved manufacturer for the Eurofighter project.
Knitted wire mesh filters are a key component in many types of gas detection equipment, assisting in essential processes such as gas flow and gas recognition.
Knitted wire mesh has a unique interlocking asymmetrical wire loop structure that when made up into multi layered filter pads creates a tortuous path that is highly effective for particle capture and elimination of entrained materials and droplets in air and vapour flows.
Such filters are used in a variety of military vehicles and are suitable for diverse terrains and climates.
