Copper mesh is a woven metal screen made from pure copper wire, and it is one of the most versatile materials you can buy. Copper mesh uses range from blocking rodents and deterring slugs in the garden to shielding sensitive electronics from electromagnetic interference. Whatever your project, copper wire mesh offers properties that fiberglass and aluminum screen simply cannot match.

At Metro Screenworks, we carry 99.99% pure copper screen mesh in a range of sizes for home, garden, commercial, and technical applications. Whether you need a single roll or bulk commercial quantities, we cut to your specifications.

What Is Copper Mesh?

Copper mesh, also called copper wire mesh or copper screen mesh, is a woven screen material made from pure copper wire. The wire is woven into an open grid, with the mesh count (wires per inch) varying by application. A finer mesh has more wires per inch and smaller openings. A coarser mesh has fewer wires and larger openings.

Unlike fiberglass or aluminum screen, copper is naturally conductive, antimicrobial, and corrosion-resistant. These properties make it useful far beyond window and porch screening, and they are why copper mesh commands a higher price point than standard screen materials.

Why Copper Mesh Is So Effective

Copper screen mesh performs well across a wide range of applications because of its unique combination of physical properties:

• High electrical conductivity: Copper is one of the most conductive metals available, making it the material of choice for EMI and RFI shielding and Faraday cage construction.
• Corrosion resistance: Copper develops a natural patina rather than rusting, making it durable in outdoor and humid environments over many years.
• Flexibility: Copper wire mesh can be cut, shaped, and formed to fit irregular openings and custom project dimensions.
• Natural antimicrobial properties: Copper inhibits the growth of bacteria and fungi, which contributes to its effectiveness in pest deterrence and specialty applications.
• Pest deterrence: Slugs, snails, and rodents avoid copper because contact with the metal creates a mild reaction that repels them.

Common Uses for Copper Mesh

We use Copper screen wire for a wide variety of diverse applications. From faraday cages for electronic devices, to window screens, jewelry, wiring, clothing, electronics, and more! Stick around to learn more about this incredible metal and its many uses.

Pest Control & Gardening

One of the most popular copper mesh uses is in the garden. Slugs and snails avoid crossing copper because contact with the metal creates a mild deterrent reaction. Placing copper mesh for slugs around garden beds, raised planters, and greenhouse entrances is a non-toxic way to protect plants without pesticides.

Copper mesh for pests is also widely used for rodent control. Stuffed into weeping holes, wall gaps, and utility entry points, it blocks mice and rats from entering a structure without restricting airflow. Unlike steel wool, copper mesh will not rust or break down over time, making it a long-lasting solution. For copper mesh gardening applications, it can also be used as a protective liner around root vegetables and bulbs.

Faraday Cages & EMI/RFI Shielding

Copper mesh is one of the most effective materials for building a Faraday cage. A Faraday cage is an enclosure made from conductive material that blocks electromagnetic fields from entering or leaving. Data centers, research labs, universities, and private users all use copper mesh Faraday cages to protect electronics from EMI and RFI interference.

Copper mesh EMI shielding is used to protect servers, cell phones, generators, and other sensitive equipment. Because copper screen mesh is flexible and can be ordered in custom sizes, it is a practical material for both small DIY enclosures and large commercial shielding installations. Metro Screenworks carries commercial-grade copper mesh rolls in bulk for these applications.

Window Screens & Architectural Design

Copper screen mesh provides the same insect protection as standard window screen but with a natural, premium look that improves with age. Pure copper screens develop a green patina over time. For porch and window screening, Brite Bronze Screen (90% copper, 10% zinc) is a popular alternative that ages to a refined dark bronze rather than green, giving it a polished, lasting appearance.

Copper mesh works especially well in coastal, historic, and vintage homes where the natural aging of the material fits the aesthetic. It can also be used for roofing accents, cabinet door inserts, and other architectural elements.

DIY & Home Decor Projects

Copper mesh is a practical and attractive material for copper mesh DIY projects. Because it can be cut with standard shears and shaped by hand, it is accessible for most skill levels. Common copper mesh projects include:

• Cabinet door inserts: Replace solid panels or standard glass with copper mesh for a warm, industrial look
• Lampshades: Form copper wire mesh around a lamp frame for filtered, warm light
• Storage baskets and organizers: Shape coarser mesh into open-weave containers
• Room dividers: Use copper mesh panels as a decorative partition between spaces

Industrial & Electrical Applications

Copper's conductivity makes it a standard material in industrial and electrical settings. Copper wire mesh is used in the production of printed circuit boards, integrated circuits, heat sinks, and heat exchangers. It is also used in electromagnets and vacuum tubes.

In electronics manufacturing, copper mesh supports heat transfer and shielding functions that other metals cannot perform as efficiently. Its combination of conductivity and formability makes it the preferred material in many industrial applications where aluminum or steel would be insufficient.

Copper Wire For Gardening

Pure Copper Screen can both promote plant growth and deter slugs and snails, making it a great product for gardens and greenhouses. Copper's natural electric charge keeps pests out of your garden, and allows it to flourish!

Copper Jewelry

Though many people love the look of copper jewelry, there is another reason many people choose to wear copper. Many people attest that Copper can help relieve arthritis symptoms. Th

ough this claim is currently unsupported by science, many people wear copper jewelry in hopes of finding relief.

How to Choose the Right Copper Mesh

Choosing the right copper screen mesh comes down to three factors: mesh count, wire diameter, and intended use.

Mesh count refers to the number of wires per inch. A finer mesh has smaller openings and is better for pest control, EMI shielding, and filtration. A coarser mesh has larger openings and works better for decor and architectural applications.

Wire diameter affects strength and flexibility. Thicker wire creates a more rigid panel. Thinner wire is more flexible and easier to shape for custom projects.

Matching copper mesh to your use case:

• Pest control and rodent blocking: Use a fine, rigid mesh that cannot be chewed through or compressed
• EMI/Faraday shielding: Use a fine copper screen mesh with high wire density for maximum shielding effectiveness
• Decor and DIY: Use a medium-weight mesh that is easy to cut and form
  by hand
• Window and porch screening: Use a standard mesh count similar to regular insect screen

Pure Copper vs. Brite Bronze Mesh

Metro Screenworks offers two copper-based screen options, and the right choice depends on your application.

Pure copper screen mesh is made from 99.99% copper. It is the right choice for EMI shielding, Faraday cage construction, pest control, and any application where maximum conductivity is required. Over time, pure copper develops a green patina.

Brite Bronze mesh is made from 90% copper and 10% zinc. It is better suited for window screens, porch panels, and architectural applications where appearance matters. Brite Bronze ages to a dark bronze color rather than green, giving it a refined, lasting look. Both are available in custom sizes and bulk rolls.

Where to Buy Copper Mesh

Metro Screenworks carries pure copper screen mesh in custom sizes and bulk rolls. All orders are cut to your specifications, so you can get exactly what you need whether you are working on a single window opening or a large commercial shielding project.
