Industry Leading Precision
& Electrical Performance

Defining the standard for conductive metal wire mesh through advanced expanding technology.

Our expanded copper mesh represents the pinnacle of metal wire product engineering. Unlike traditional woven mesh, our expanded process creates a seamless, monolithic structure that eliminates weld points and minimizes electrical resistance. This makes it the primary choice for high-frequency EMI shielding and critical electrical grounding applications where failure is not an option.

By leveraging ultra-pure copper alloys and precision slitting techniques, we achieve an exceptional strength-to-weight ratio. The resulting open-area architecture allows for maximum airflow and liquid passage while maintaining superior conductivity and corrosion resistance, ensuring long-term reliability in harsh chemical or high-temperature environments.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries regarding expanded copper mesh.

01

What is the difference between expanded copper mesh and woven copper mesh?

Expanded mesh is created by slitting and stretching a solid sheet of copper, resulting in a monolithic structure without seams or welds. Woven mesh is made by interlacing wires. Expanded mesh typically offers higher structural stability and lower electrical resistance.

02

How does expanded copper mesh provide EMI shielding?

The conductive copper structure reflects and absorbs electromagnetic waves. By creating a continuous conductive envelope (Faraday Cage), it prevents external RF interference from reaching internal electronic components.

03

Can the mesh be customized for specific aperture sizes?

Yes, we can customize the slitting and stretching ratios to achieve precise aperture dimensions (openings) and strand widths to meet your specific filtration or shielding requirements.

04

Is tinned copper available for corrosion resistance?

Yes, we offer tinned expanded copper mesh which provides an additional layer of protection against oxidation and corrosion, making it ideal for humid or chemically active environments.

05

What is the standard lead time for custom orders?

Sample orders typically ship within 7 days. Full production lead times vary by volume but generally range from 2 to 4 weeks, including quality testing and certification.

06

How is the conductivity of your mesh verified?

We use four-point probe testing and resistivity meters to verify that the copper mesh meets IACS standards, ensuring consistent electrical performance across the entire roll or sheet.
