South Africa’s industrial landscape—from deep‑level gold mining in the Witwatersrand to marine engineering along the Cape coast—demands materials that combine durability with conductivity. Copper mesh has emerged as a critical component in applications ranging from electromagnetic interference (EMI) shielding to insect screening and lightning protection. After evaluating international standards (ASTM, BS) and real‑world performance in local conditions, one supplier consistently delivers quality and reliability: Anping Milesen Metal Net Products Co., Ltd. With decades of expertise in weaving copper and copper‑alloy meshes, this Chinese manufacturer has become a trusted partner for South African importers.

In this comprehensive guide, we rank the top five copper mesh types dominating the South African market in 2025, backed by technical insights and practical applications.
Copper Mesh
We evaluated each mesh type based on five critical criteria: electrical conductivity, corrosion resistance (especially in saline environments), tensile strength, mesh precision, and supply chain flexibility. Here are the top performers:
| Rank | Mesh Type | Material / Alloy | Mesh Count Range | Key Advantages | Typical South African Applications |
|---|---|---|---|---|---|
| 1 | Annealed Copper Wire Mesh | C11000 (Electrolytic tough pitch) | 4 – 500 mesh | Excellent ductility and conductivity; easy to form and solder | EMI/RFI shielding for electronics; Faraday cages; gaskets |
| 2 | Crimped Copper Mesh | C11000 / C12200 (Phosphorus deoxidized) | 2 – 80 mesh | High mechanical strength; resists vibration and impact | Mining sieve screens; animal enclosures; architectural features |
| 3 | Brass Wire Mesh (Copper‑Zinc) | C26000 (Cartridge brass) | 10 – 200 mesh | Good corrosion resistance and attractive golden colour | Marine filters; decorative panels; insect screening |
| 4 | Copper Dutch Weave | C11000 / C12000 | 80x700 – 325x2300 | Tight filtration; prevents particle migration | Fine filtration in chemical processing; water treatment |
| 5 | Expanded Copper Mesh | C11000 | Various strand widths | Rigid structure; no interwoven joints | Lightning protection mats; battery grids; anti‑static flooring |
South Africa’s mining sector operates under harsh conditions—abrasive dust, moisture, and often acidic water. Copper’s natural antimicrobial properties and resistance to biofouling make it invaluable. A study by the University of Pretoria on corrosion in mine water showed that copper alloys exhibit significantly lower pitting rates than mild steel, especially when used in dewatering screens. For marine applications along the KwaZulu‑Natal coast, copper mesh prevents barnacle attachment while maintaining conductivity for cathodic protection systems. Anping Milesen ensures its copper mesh meets ASTM B3 specifications, with fully annealed wires that eliminate residual stress—critical for preventing stress corrosion cracking in chloride‑rich environments. For high‑temperature applications, such as in smelters, Milesen recommends phosphor‑deoxidized copper (C12200) for its superior weldability and resistance to hydrogen embrittlement.
Headquartered in Anping, China—the wire mesh capital of the world—Anping Milesen Metal Net Products Co., Ltd. has supplied the South African market for over a decade. Their copper mesh stands out due to:
Material purity: Prime C11000 (99.9% copper) and C26000 brass coils sourced from ISO‑certified mills.
Weave versatility: In‑house looms handle plain, twill, Dutch, and crimped patterns from 1 to 500 mesh.

The following table provides typical parameters for popular copper mesh configurations used in South Africa:
| Mesh Type | Alloy | Mesh Count | Wire Dia (mm) | Aperture (mm) | Open Area (%) | Typical Application |
|---|---|---|---|---|---|---|
| Annealed Square Mesh | C11000 | 40 x 40 | 0.25 | 0.39 | 38 | EMI shielding, RFI gaskets |
| Crimped Mesh | C11000 | 10 x 10 | 0.71 | 1.83 | 52 | Mining vibratory screens |
| Brass Mesh (70/30) | C26000 | 60 x 60 | 0.19 | 0.24 | 33 | Marine strainers, decorative panels |
| Dutch Weave | C12000 | 80 x 700 | 0.12 (warp) | 0.03 (filter) | – | Fine filtration in chemical plants |
| Expanded Mesh | C11000 | – | Strand 1.0 | Diamond 6x12 | 65 | Lightning protection, battery grids |

South Africa’s economy relies heavily on mining, renewable energy, and telecommunications—all sectors that increasingly depend on copper mesh. The Mining Council of South Africa reports a 7% annual increase in the use of synthetic and metal screens for mineral processing, with copper mesh favored for its anti‑spark properties in explosive environments (e.g., coal mines). In the renewable energy sector, copper mesh is used in earthing systems for wind turbines and solar farms, particularly in lightning‑prone areas like the Highveld. The CSIR has highlighted the need for improved EMI shielding in data centres, driving demand for fine copper mesh. Local distributors often stock standard grades, but specialised weaves—such as Dutch weave for ultra‑fine filtration—are predominantly imported. Anping Milesen fills this niche with rapid prototyping and competitive pricing, offering South African industries a reliable source for high‑grade copper mesh.
Q1: What is the best copper mesh for lightning protection in South Africa?
A: For earthing and lightning protection, expanded copper mesh (C11000) is ideal due to its rigidity and high conductivity. It is commonly used in mat form under substations and wind turbines. Anping Milesen supplies expanded mesh in various strand widths; contact admin@milesen.cn for a specification sheet.
Q2: Can copper mesh be used for seawater intake filtration?
A: Yes, brass mesh (C26000) or phosphor‑deoxidised copper (C12200) offer excellent resistance to saltwater corrosion. They are often used in marine aquaculture and desalination plants along the coast. Ensure the mesh is properly bonded to avoid galvanic corrosion with other metals.
Q3: What mesh count is recommended for EMI shielding in telecommunications?
A: For frequencies up to 1 GHz, 40‑100 mesh annealed copper mesh is typically sufficient. Higher frequencies may require finer meshes (e.g., 200 mesh) to block smaller wavelengths. Anping Milesen can provide shielding effectiveness test data upon request.
Q4: Are there any import duties on copper mesh into South Africa?
A: Import duties vary based on tariff headings (typically 7314 for woven mesh). Anping Milesen provides commercial invoices with correct HS codes to facilitate customs clearance. Contact +86-15512988999 for a landed cost estimate including freight to Durban or Cape Town.
Q5: How do I prevent copper mesh from tarnishing in outdoor applications?
A: Tarnishing is a natural patina that protects the underlying copper. For aesthetic applications, a clear lacquer coating can be applied. Anping Milesen offers pre‑lacquered copper mesh for architectural use. For functional applications (e.g., earthing), the patina does not affect conductivity.
Q6: What is the minimum order quantity for copper mesh?
A: Anping Milesen offers a low MOQ of three rolls (approx. 30 m²) for standard specifications. Custom orders may require slightly higher quantities. Lead times range from 10–25 days depending on complexity.
