Expanded Metal Mesh with Precise Aperture and Dimensional Stability

Micron expanded mesh, made from stainless steel, aluminum, or copper, offers precise aperture control, high strength, and durability for industrial filtration. Its uniform openings ensure stable particle separation under high pressure or extreme temperatures. Common applications include liquid and gas filtration in chemical, oil and gas, pharmaceutical, and food industries. Compared with woven wire mesh, it resists clogging and deformation, extending service life and reducing maintenance. Stainless steel provides corrosion resistance, while aluminum and copper offer lightweight or conductive options.

Pumps and reactors

Used in filter screens for pumps and reactors to remove particulates from aggressive chemical solutions, thanks to its corrosion resistance and high-temperature stability.

Automobiles

Utilize expanded metal as the primary support structure in airbag inflators, oil filtration and hydraulic systems.

HVAC Systems

Applied in commercial air handling units for particulate filtration, benefiting from aluminum’s light weight and non-sparking properties.

When integrated into composite structures or radomes, micron expanded mesh provides a low-resistance path for lightning current to flow across the surface and safely dissipate, preventing damage to critical internal components and systems. Its open structure helps maintain aerodynamic efficiency while providing effective electromagnetic shielding and grounding, making it ideal for protecting sensitive areas such as wings, nose cones, and rotor blades.

Microporous expanded metal mesh is embedded into composite surfaces and structures to dissipate electrical energy after a lightning strike. It is available in aluminum or copper materials, typically in widths of 500–1000 mm, and is commonly used in the following areas:

• Fuselage
• Wings
• Rudder
• Vertical Stabilizers
• Spoilers
• Ailerons
• Vanes
• Flaps
• Slats
• Engine Nacelles
• Belly Fairings
• Winglets
• Helicopter – Rotary Blades & Radar Antennae

Installed on the Turbine Blades surface and Generator Nacelles – especially at the tips and leading edges where strikes are most common – the micron expanded mesh provides a controlled path for lightning current to safely travel and dissipate into the turbine structure and ground. This prevents catastrophic damage to the composite blade material and internal components. The mesh's open design minimizes weight and aerodynamic impact while ensuring effective conductivity and durability, making it a reliable solution for protecting wind turbines in high-risk environments.

Steel mesh is a core material for lightning protection in composite buildings. With excellent electrical conductivity, it can quickly discharge high lightning currents and disperse lightning energy through its mesh structure, preventing material damage. Installed by adhering to the surface or embedding within structural components, it does not affect the building’s original properties while effectively mitigating lightning hazards caused by the insulating nature of composite materials.

Micron expanded copper mesh offers excellent conductivity and balanced aperture design, making it ideal for EMI (Electromagnetic Interference) shielding.

It reflects and absorbs electromagnetic waves to protect sensitive electronics and prevent signal leakage.

The fine mesh ensures airflow and visibility while maintaining strong shielding, suitable for electronic enclosures, communication devices, medical instruments, and aerospace systems.

Micron expanded mesh, made from high-conductivity and corrosion-resistant materials such as stainless steel, nickel, titanium, or copper, is widely used as a current collector in advanced energy applications.

Its uniform aperture, high strength, excellent conductivity, and large surface area make it ideal for electrochemical systems.

• High conductivity and low resistance
• Strong adhesion for electrode coatings and catalysts
• Improved electrolyte flow and ion transport
• Durable under repeated charge/discharge cycles
• Customizable pore size for optimized performance

Lithium-Ion and Solid-State Batteries

Application:

Used as a current collector in high-power battery anodes (e.g., silicon-based anodes) and cathodes (e.g., NMC, LFP).

Benefit:

Electrolyzers (Green Hydrogen Production)

Application:

Serves as anode and cathode substrates in PEM (Proton Exchange Membrane) and alkaline electrolyzers.

Benefit:

Titanium micron expanded mesh (anode) resists oxidation in oxygen-evolving environments; nickel-plated steel or nickel mesh (cathode) supports hydrogen evolution with high efficiency and durability.

Fuel Cells

Application:

Used as gas diffusion layers (GDLs) or bipolar plate components in PEM fuel cells.

Benefit:

Ensures uniform gas flow, water management, and electron conduction while maintaining structural stability.

High-Voltage Transformer Test Laboratories

Expanded copper mesh, made from high-purity electrolytic copper, is widely used in high-voltage transformer test laboratories as a high-performance grounding system due to its excellent electrical conductivity, corrosion resistance, and mechanical durability.

• Superior conductivity – ensures low-impedance grounding for safety and measurement accuracy.
• High current-carrying capacity – safely dissipates large fault or test currents.
• Corrosion resistance – maintains long-term reliability in indoor lab environments.
• Easy integration – can be welded or brazed into continuous grounding grids with minimal joints.
• Electromagnetic shielding – reduces interference during sensitive high-voltage measurements.

• Test Chamber Grounding Grid:

  Installed under the floor or on walls of transformer test cells, it forms an equipotential plane.

  Keeps all equipment and test objects at the same potential, improving operator safety and test accuracy.

• Equipment Grounding Busbars:

  Connect high-voltage test equipment (AC/DC test sets, measuring dividers, coupling capacitors) to the main earth grid.

  Minimizes ground loops and potential differences, ensuring safe and accurate testing.

• Shielded Enclosure Lining:

  Installed on walls or doors of shielded rooms to form a Faraday cage.

  Expanded mesh provides EMI shielding and ensures continuous grounding.

• Temporary Test Grounding:

  Copper mesh sections with clamps serve as safety grounding straps.

  Discharges residual energy from tested transformers before handling.

• Grounding of Test Fixtures and Scaffolding:

  Wrapped or bonded to support structures near high-voltage setups.

  Eliminates floating potentials and prevents arcing.

• Copper mesh is 100% recyclable;
• Its carbon footprint is 42% lower than that of aluminum mesh (based on ISO 14064 life cycle assessment).
