Copper Expanded Metal Mesh
🔶 Copper Expanded Metal Mesh
Product Overview
Asian Strek Metals’ Copper Expanded Metal Mesh is a premium architectural and industrial material manufactured by precision slitting and stretching copper sheets into a rigid, lightweight mesh structure without welding or joints. Known for its natural corrosion resistance, warm metallic appearance, and excellent conductivity, copper expanded mesh is ideal for decorative, functional, and performance-driven applications.
Over time, the surface naturally develops a protective patina finish, making it especially popular for exterior façades and architectural installations where both durability and aesthetics are essential.

Features
Copper Expanded Metal Mesh for High-Voltage Laboratories
Product Overview
Asian Strek Metals’ Copper Expanded Metal Mesh is a critical safety and performance material engineered specifically for high-voltage testing laboratories, substations, and sensitive electrical environments. Manufactured from high-purity copper sheets through precision expansion, the mesh forms a seamless, rigid structure without welding or joints — ensuring superior electrical continuity, mechanical stability, and long-term durability.
This material is widely used in grounding systems, Faraday cages, and electromagnetic shielding enclosures where measurement accuracy, personnel safety, and system reliability are non-negotiable.
All-rounded Protection
Key Functions in High-Voltage Laboratories
Faraday Cage Construction & EMI Shielding
Copper expanded mesh is installed on laboratory walls, ceilings, and floors to form a complete electromagnetic shield enclosure, preventing external electromagnetic and radio-frequency interference (EMI/RFI). This ensures ultra-low background noise levels — essential for accurate partial discharge (PD) testing, transformer testing, and high-voltage cable diagnostics.
Equipotential Grounding Grid
Laid beneath laboratory floors, the mesh creates a high-performance grounding system. With copper’s superior conductivity (up to 101% IACS), it provides a low-impedance path for safely dissipating fault currents and test discharges into the earth, maintaining equal electrical potential across the entire test area.
Noise Reduction & Signal Integrity
Using 99.99% oxygen-free or ETP-grade copper mesh, laboratories significantly reduce electromagnetic noise that could otherwise distort sensitive high-voltage measurements and test results.
Safe Discharge of Residual Energy
Copper expanded mesh is also used as grounding straps and discharge paths to safely neutralize residual energy stored in test equipment before handling, ensuring maximum personnel protection.
Why Choose ETP Grade Copper Expanded Mesh?
✔ Maximum Electrical Conductivity
Rated at minimum 101% IACS, providing the lowest resistance path for fault current dissipation.
✔ Superior Corrosion Resistance
Naturally forms a protective oxide layer (patina), ensuring long-term durability even in underground or moisture-prone environments.
✔ Excellent Thermal Performance
High thermal conductivity allows rapid heat dissipation during surge events, preventing localized overheating or damage.
✔ Long Service Life
Maintains structural and electrical integrity for decades with minimal maintenance
