Micro Expanded Metal – Various Materials and Versatile Applications

MEM-01: Micro expanded metal has fine thickness and small meshes.

Micro expanded metal, a kind of special expanded metal, is made from a high quality fine steel sheet of aluminum, carbon steel, galvanized steel or stainless steel that is uniformly slit and stretched into diamond, hexagonal and other hole patterns you want. Different hole patterns can be used for different applications, which can permit the light, air, heat and sound passage.
The main technology of micro expanded metal is stretching and expanding, which will not lose any material, so it is much more economical alternative to perforated metal.

Micro expanded metal is a very versatile and economical product, which is widely used as filter elements support, speaker grill covering, rain gutter filter, battery grid plate and other wide range of applications.

Applications of micro expanded metal

  • Gutter filter.
    Micro expanded metal can be used individually or used combined with woven wire mesh as gutter filter. It can block falling leaves entering and blocking the gutter. The meshes permit air, sunlight and rain passing through to ensure the gutter dry and clean. Additional, the small meshes of expanded metal and woven wire mesh can keep out wasps and other pests. When you use it, just fasten them on existing rain gutters, no need to replace existing rain gutter.

  • MEM-08: Micro expanded metal is used individually for blocking leaves.

    MEM-09: Micro expanded metal is used with woven wire mesh for better filtering and blocking.
  • Batteries grid plate.
    The micro expanded metal is key component in battery manufacturing. It is flexible and with high surface area and cost-effective. The mesh openings allow fluids flowing through them. Additional, the micro expanded metal is conductive, it allows the transport of the protons from the anode to the cathode through the membrane. The micro expanded metal can be made into coils, discs and almost any shapes as required.

  • MEM-10: Copper micro expanded metal has excellent conductive performance.

    MEM-11: Micro expanded metal is widely used in battery manufacturing.
  • Filtration.
    The micro expanded metal with fine thickness, prevision engineered mesh openings, percent open area is widely used as filtration material in physical, chemical and other applications. Additional, the micro expanded metal can provide a consistently high level of precision and strength. Micro expanded metal has good filtering or retention performance no matter for air, light, solid or liquid.

  • MEM-12: Filter disc – micro expanded metal.

    MEM-13: Filter cylinder – micro expanded metal.

    MEM-14: Filter bowl – micro expanded metal.

    MEM-15: Micro expanded metal support grid.
  • EMI/RFI shielding.
    Micro expanded metal can blocking and shielding Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI) and other interference or unwanted frequency signals in aerospace, automotive, telecommunication or electronics industry. It adopts copper or other conductive materials to supply efficient shielding. Shapes, sizes and shielding performance can be customized according to your requirements.
  • Speaker grill covering.
    Micro expanded metal provides excellent sound absorption and reducing the decibel levels in acoustic noise reduction applications. It is widely used in the microphones, loud speakers, speaker grilles to protect sensitive membranes while allowing a uniform permeability of sound.

  • MEM-16: Micro expanded metal can be used in microphone for better sound quality.

    MEM-17: Micro expanded metal can be used as loudspeaker covers on the car.
  • Other applications of micro expanded metal
    • Daily supplies.
    • Plant supporting shelves.
    • Metal gratings.
    • Sun shading.
    • Screening.
    • Ceiling.

  • MEM-18: Micro expanded metal sunshade screening.

    MEM-19: Micro expanded metal ceiling.

    MEM-20: Micro expanded metal furniture.

    MEM-21: Micro expanded metal document basket.
