Copper Wire Mesh

Tianjin Hengai Metal Products Co., Ltd specializes in the manufacture and export of copper wire mesh products, offering a diverse range of applications due to the inherent properties of copper and its alloys. Our copper wire mesh, recognized for its ductility, malleability, and superior thermal and electrical conductivity, serves a wide array of industries and purposes. These include, but are not limited to, RFI shielding, construction of Faraday cages, innovative roofing solutions, HVAC system components, and an assortment of electrical applications.

Our copper wire mesh, though softer compared to stainless steel alternatives, boasts remarkable durability and an inherent resistance to atmospheric corrosion. This resilience, however, does not extend to certain oxidizing agents such as nitric acid, ferric chloride, cyanides, and ammonia acid compounds, which can affect the mesh. In compliance with ASTM E-2016-11, a recognized industry standard, our products are crafted from 99.9% pure copper. This not only ensures quality and reliability but also leads to the natural formation of a thin, protective green patina over time when exposed to the elements. This unique characteristic enhances the aesthetic appeal while maintaining the functionality of the mesh.

Tianjin Hengai Metal Products Co., Ltd  is committed to providing high-quality copper wire mesh products that meet the evolving needs of our customers, ensuring satisfaction and utility in a variety of settings.

Types of Copper Wire Mesh

• Plain Weave Copper Mesh: Plain weave copper mesh, characterized by its simple over-and-under weaving pattern, is the most common and versatile type. Each weft wire crosses alternately above and below each warp wire, creating a uniform and square opening. This mesh is typically used for general screening and filtration applications. Its balanced structure offers a combination of good strength and open area, making it suitable for various industrial, architectural, and design uses. Plain weave mesh is often chosen for its ease of handling and consistency in performance.

• Twill Weave Copper Mesh: Twill weave copper mesh is distinguished by each weft wire passing over and under two warp wires in a staggered manner. This creates a diagonal pattern and allows for the use of heavier wires and tighter mesh openings. Twill weave provides enhanced strength and is ideal for applications requiring finer filtration. It’s often utilized in industrial processes where durability and filtration precision are key. The unique structure of twill weave mesh makes it more pliable and suitable for applications where a sturdier mesh is required.

• Dutch Weave Copper Mesh: Dutch weave copper mesh is known for its fine filtration capabilities. The weave pattern involves a tight, dense arrangement of thinner warp wires and thicker weft wires. This configuration results in smaller openings and higher filtration accuracy, making Dutch weave mesh ideal for demanding filtration processes in the petrochemical and pharmaceutical industries. The structure is robust and offers excellent strength and stability, ensuring long-lasting performance in high-pressure environments. Dutch weave mesh is the go-to option for precision filtering needs.

• Crimped Copper Mesh: Crimped copper mesh features wires that have been pre-crimped before weaving, creating a rigid and stable structure. The crimping process allows for larger openings and increases the structural integrity of the mesh. This type is mainly used in architectural and decorative applications, offering both aesthetic appeal and functionality. The unique texture of crimped mesh adds visual interest and is often employed in façade cladding, interior design, and garden landscaping. It’s also used for protective screens, offering a balance of visibility and security.

• Knitted Copper Mesh: Knitted copper mesh, made by interlocking loops of wire, is known for its exceptional flexibility and stretchability. This mesh type is ideal for applications requiring adaptability and moldability, such as RFI shielding, gaskets, and even pest control. The knitting process creates a mesh that can conform to various shapes and absorb vibrations, making it useful in automotive and aerospace industries. Knitted mesh is also used in filtration, where its ability to trap particles while maintaining airflow is beneficial.

• Expanded Copper Mesh: Expanded copper mesh is produced by slitting and stretching solid copper sheets, creating a distinctive diamond-shaped pattern. This process results in a rigid and strong mesh, often used for outdoor architectural elements, security barriers, and various industrial applications. The expanded mesh offers excellent strength-to-weight ratio and good ventilation, making it ideal for protective screens, walkways, and ventilation grilles. Its aesthetic appeal also lends itself to decorative uses in building facades and interior design.
