EMI-shielding

Whether in vehicles, electronic devices, or critical infrastructure, EMC shielding with GKD metal mesh provides reliable protection against electromagnetic interference everywhere.

Our woven shielding solutions are already being used in automobiles today. In addition, they also open up new possibilities for efficiently protecting sensitive electronics in areas such as data centers, medical technology, aerospace, displays, and even household appliances.

In this way, we are responding to increasing networking and digitalization, which require the highest level of electromagnetic compatibility in all these industries.

Data centers and IT infrastructure

In high-security data centers, server rooms are often shielded as Faraday cages to protect hardware from interference. Our metal mesh can be used here, for example, in ventilated rack doors or wall elements.

It blocks electromagnetic interference (EMI) while allowing the necessary airflow. In this way, our mesh helps to comply with strict EMC requirements (e.g., TEMPEST standards).

Screens and displays

A fine-mesh metal fabric can be integrated into monitors, touchscreens, and display instruments as a transparent shield without impairing visibility.

Such almost invisible EMI shielding meshes can be embedded directly into display front glasses or laminated between panes. The readability of the screen is maintained while the device is protected from incoming and outgoing radiation – for example, in medical technology, where displays must be both transparent and EMC-safe.

Industrial electronics and control systems

In production facilities, robots, or control cabinets, sensitive control devices must be protected from interference fields (e.g., from motors or frequency converters). Here, wire mesh can serve as a shield in plastic housings or at openings (e.g., as fan grilles).

They attenuate electromagnetic emissions and block external interference. Unlike completely enclosed metal housings, grilles still allow air cooling and flexible component design.

Functional principle: Shielding with conductive mesh

Metal meshes work according to the Faraday principle. Electromagnetic fields are reflected by the conductive structure and attenuated by electrical losses. The following factors are decisive:

Conductivity and surface condition of the material
Electrical contact to the shielding structure and defined ground connection
Freedom from gaps and low-resistance transitions in the overall system

Mesh size and wavelength fundamentally influence the shielding effect, but due to the typical frequency ranges to be shielded, the effects here are too small. In real assemblies, however, contact, joints, openings, and the structure of the overall system often have a greater influence on the resulting shielding attenuation than the fine variation of a single mesh geometry.

Technical parameters that matter in projects

For EMC shielding meshes, project-specific characteristics are considered and coordinated, for example:

Shielding attenuation in dB as a system value from fabric, installation, and grounding
Electrical resistance as an indication of conductivity
Thickness and weight per unit area for fabric integration in composite materials or glass composites
Optical transparency and low reflectivity due to black coloring

Mesh selection is based on the entire requirement profile: shielding objective, mechanical constraints, optical requirements, media and temperature resistance, installation concept.

Materials and mesh types

The choice of material depends on electrical conductivity, corrosive environment, and integration requirements.

Copper and copper alloys for low resistance and high shielding effectiveness
Aluminum alloys for weight-sensitive applications
Stainless steel for mechanically robust, corrosion-resistant applications

Black-coated variants reduce reflections in optical applications. Such fabrics are typically integrated into components as semi-finished products, not as self-stable, ready-to-assemble parts.

Typical applications

Visible surfaces and optical components: displays, windows, covers with EMC function
Integrated fabrics: inserts in plastic or composite components, laminates, and housing elements
Electronic assemblies: shielding areas on openings, interfaces, control elements, covers

Integration: crucial for the resulting shielding attenuation

Effectiveness depends entirely on integration. Project requirements:

Extensive, conductive integration into the shielding structure
Defined ground connection, low-resistance contact
Controlled joints and transitions, minimized gaps
Coordinated concept for seals, frames, clamps, or laminate construction

This turns the mesh into a reproducible shielding function in the overall system.
