Gupta Metal Mesh

We are Leading Manufacturer and Supplier of Copper Expanded Metal Mesh, Manufacturing in Delhi.

EXPANDED METAL MESH

Expanded metal is frequently used to make fences, walkways, and grates, as the material is very durable and strong, unlike lighter and less expensive wire mesh. The many small openings in the material allow flow through of air, water, and light, while still providing a mechanical barrier to larger objects.

It is manufactured from a copper coil, which is cut, expanded then flattened to create its pattern / look.

Copper expanded metal mesh is produced by slitting and stretching a Single metal sheet to form various opening shapes. There are two styles of standard and flattened. Flattened expanded metal mesh based on standard metal mesh undergoes an additional cold rolling process, creating a smoother surface.

Copper expanded metal sheets are indeed used for electromagnetic shielding purposes. Electromagnetic shielding is the practice of using materials that can block or redirect electromagnetic radiation to protect sensitive equipment or living spaces from interference or exposure to electromagnetic fields. Copper is a popular choice for this purpose due to its excellent electrical conductivity and high shielding effectiveness.

Here are some key points to consider when using copper expanded metal sheets for electromagnetic shielding:

1. Material Choice: Copper is often selected for its high electrical conductivity, which allows it to effectively absorb and disperse electromagnetic radiation. The expanded metal sheet provides both structural support and the desired electromagnetic shielding properties.

2. Sheet Design: Expanded metal sheets are created by slitting and stretching a sheet of metal, resulting in a mesh-like structure with interconnected strands. The design of the expanded metal can be chosen based on the specific shielding requirements, such as the frequency range of electromagnetic radiation to be shielded.

3. Shielding Effectiveness: The effectiveness of copper expanded metal for electromagnetic shielding depends on the design of the sheet and its thickness. Thicker sheets or smaller mesh sizes are more effective at blocking higher-frequency electromagnetic waves.

4. Applications: Copper expanded metal sheets are used in a wide range of applications, including in electronic devices, MRI rooms, military equipment, and in the construction of Faraday cages. They can also be incorporated into building materials to shield entire rooms from external electromagnetic interference.

5. Installation: Proper installation is crucial for effective electromagnetic shielding. Sheets should be installed with overlapping seams, and any gaps or seams should be adequately sealed with conductive tape or gaskets to ensure continuous shielding.

6. Testing: To ensure the desired level of electromagnetic shielding, it's important to test the shielding effectiveness of the copper expanded metal sheets. This can be done using specialized equipment that measures the attenuation of electromagnetic fields.

7. Maintenance: Over time, the effectiveness of shielding materials can degrade due to corrosion or other factors. Regular maintenance and inspections are necessary to ensure continued protection.

When selecting copper expanded metal sheets for electromagnetic shielding, it's essential to work with knowledgeable engineers or experts who can help you choose the right materials and design for your specific application and requirements. Keep in mind that while copper is highly effective for many applications, there may be specialized materials or configurations needed for certain frequencies or environments.
