We offer a wide range of specialist knitted wire mesh products that provide durable solutions for the very specific performance, safety and environmental demands encountered in aggressive marine applications.
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.
Our products are used by prestigious customers such as the Royal Navy and the RNLI who operate in the most challenging marine conditions.
They feature in fire control systems in engine rooms, flame arresters in survival equipment, gaskets and tapes for Electromagnetic Compatibility (EMC) screening or electrical sealing of marine electronic equipment, and sea mist filters (mist eliminators or de-misters) used in engine room air intakes.
Our mesh can also be incorporated as a mechanical protection or support structure in thermal and/or acoustic insulation (protection jackets) for the pipes and fittings, pressure vessels and valves in engine/turbine rooms, exhaust sets, boilers and HVAC systems.
The special challenges posed by marine installations require benign, eco-friendly but high-performance materials and our all-metal meshes are inherently safe and recyclable. The self-extinguishing products are characterised by their flame resistance, shock resistance and low outgassing so, when correctly specified our products are suitable for use in the most corrosive or saline environments.
We offer a rapid, low-cost prototyping service and have the ability to knit combined-material meshes. Accordingly, we are able to fabricate bespoke solutions for your specific requirements and offer products that fully comply with the quality requirements of IATF16949 & ISO 9001.
Features Of Knitted Mesh
Suitable for operation at extremes of high and low temperatures
Excellent filtration capability
Available in materials suitable for corrosive, saline and hostile environments
Highly resilient for absorption of heat, sound, vibration energy and high shock loadings
Great for mechanical strength, good surface stability and resistance to thermal creep
Knitted wire mesh has a unique ability to absorb energy, reduce vibration and attenuate sound.
It is utilised in many different marine applications, for example, as support structures for submarine radio antenna equipment
Our mesh can be incorporated as a mechanical protection or support structure in thermal and acoustic insulation (protection jackets) for the pipes and fittings, pressure vessels and valves in engine/turbine rooms, exhaust sets, boilers and HVAC systems.
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 vessels and are suitable for diverse environmental conditions and climates.
Fire Control Equipment
Our knitted mesh features in non-water based stationary fire extinguishing systems, designed for marine engine rooms and control centres to protect vital equipment that is incompatible with water.
Compressed anti-vibration for radio antenna
KnitMesh Technologies anti-vibration, sound attenuation and heat shields are highly effective absorbers of heat, noise and vibration energy.
Knitted mesh has several properties that give it a unique ability to absorb energy. The result is a material ideal for use in many applications, able to reduce vibration, attenuate sound and dissipate heat.
