Micro Expanded Metal Mesh Stainless Steel
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.
Hole patterns of micro expanded metal can be diamond, square, round, hexagonal. Hole type of micro expanded metal raised/standard hole and flattened hole.
Materials:
Stainless Steel:201, 202, 205, 304, 304L, 316, 316L, 321
Steel: Q195, Q215, Q235
Copper: red copper plate (C10200, C11000), brass plate(CuZn40, CuZn37, CuZn35, CuZn30, CuZn20, CuZn5)
Aluminum: pure aluminum plate, aluminum alloy plate(1050, 5052, 5056)
Nickel: N2, N4, N6, nickel alloy 2080, monel 400, monel 600
Note: SS304, SS316 is the most common material.
Standard Expanded Metal is directly slit and stretched by punching machines without other processing,The strand width and bond come in with an angle with the plate surface. This kind structure increase the strength and hardness of expanded metal,it also brings better anti-slipping and reinforcing performance.
Features:
Durable.
Attractive.
One-piece construction.
Easy to install.
Excellent strength-to-weight ratio.
Low wind resistance.
Easy to cut and shear.
Available in many styles and hole patterns.
Applications:
1) 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.
2) 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.
3) 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.
4) 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.
5) 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.
6) Other applications of micro expanded metal.
Daily supplies.
Plant supporting shelves.
Metal gratings.
Sun shading.
Screening.
Ceiling.
