Goto Dashang to know more.
Wire, or space, cloth with a pre crimp mesh is woven using wire crimped prior to weaving. The crimps are made at the points the shute and warp wires intersect which secures the wire, thereby stabilizing the wire cloth and preventing the wire from moving. Additional rigidity and strength can be obtained by adding crimps between the intersections, using an intermediate crimp. Crimped wire provides a more secure fit to the mesh, limiting movement of the space cloth. This results in more accurate and consistent opening sizes within the mesh.
Pre crimp mesh is used in the waste water, oil refining, mining, construction, safety and food processing industries for applications that require strength and large-hole filtering and screening. Pre crimped wire cloth is also used in architectural and industrial design applications.
DWT’s heavy duty wire mesh is custom manufactured for products and applications requiring strength and rigidity, such as sieves and vibration filter media for sizing, sorting and filtering heavy or large materials. Heavy duty wire cloth is used in the mining, refining and construction industries.
Pre crimp wire cloth and heavy duty pre crimp mesh are manufactured by Dorstener in large wire diameters. We offer a wide range of metals and alloys for use in the mesh to meet product requirements. All products can be manufactured using DFAR and non-DFAR compliant materials. Extra-wide roll widths are available.
In this segment, we delve into the concept of metal mesh, exploring its creation process and essential design considerations.
"Wire mesh" commonly pertains to structures constituted from multiple metallic wires that are connected using various techniques, forming either flat or three-dimensional frameworks. This versatile material is widely used in transportation, fencing, display setups, and protective barriers, serving significant roles across both industrial applications and everyday use.
Sheets of metal mesh are fabricated from an assortment of materials such as stainless steel, galvanized steel, plain carbon steel, aluminum, copper, bronze, brass, among other specialized metals. These materials are processed into wires of differing gauges, which are then woven or interlinked to produce uniform parallel rows and intersecting columns.
Also known as wire fabric, wire cloth, or hardware mesh, wire mesh is manufactured by weaving wire on machinery designed for industrial looms, creating square or rectangular gaps between each strand. In the case of welded wire mesh or cloth, the intersecting wires are fused together at junctions using electric welders.
Iron-derived steel has unique and beneficial attributes. Notably, stainless steel is completely rust-proof and incredibly durable, making it an optimal choice for various industry applications. Steel wires are particularly ideal for creating wire mesh and similar products due to their notable ductility, strength, and flexibility.
Wire mesh is among the antiquities in steel production, with its utility evident over thousands of years. As global economies expand, steel wire mesh sees varied new uses such as fencing, barricades, safety covers for machines, cages, grills, sifters, and shelving solutions.
Iron welded wire mesh is indispensable in concrete reinforcement. Companies generating steel wires supply them to secondary producers who transform them into mesh using weaving or welding techniques.
Important considerations include:
Recognizing temperature thresholds is critical when deploying heat-resistant wire mesh in high-temperature settings. Since any ductile metal or alloy can be employed for woven wire mesh, choosing the right material for each task is essential. High-temperature capacities include stainless steel grade 304 (°F or 815.5°C); Inconel (°F or 982°C); nickel (°F or °C); and tungsten (°F or °C).
While many wire cloth variants can corrode, materials like titanium and certain specialized alloys such as Hastelloy, Inconel, and Nichrome offer enhanced protection against corrosive conditions.
Viscosity is a vital factor in water treatment, oil processing, and chemical filtration. Efficient filtering is noted with less dense fluids. For optimal results with highly viscous fluids, the appropriate mesh type and size must be chosen. Note that viscosity often shifts with temperature changes.
The size of particles is a significant criterion when deciding on wire mesh. Select mesh count, aperture size, and wire thickness according to the particle size intended for retention. Use test sieves for achieving specific particulate measurement.
As substances pass through a filter, pressure decreases and contaminants are eliminated. The selected filter media has a significant impact on this pressure drop rate. Upon reaching a certain drop point, filter replacement is necessary. Aligning wire mesh selections with your pressure drop requirements aids in cost reduction and fewer contamination incidents.
Viscosity, pressure drop, and flow rate are interlinked. Choose the appropriate mesh aligning with specific flow rate needs while considering the mesh's open area percentage.
The type of pollutants encountered affects decisions on material, wire diameter, mesh density, tolerance levels, aperture size, and wire weave style.
Mesh settings may need adjustments based on usage. In production, wire mesh baskets and sieves assess and measure specific gravity of filtered substances. These products, usually brass or stainless steel, should be selected based on specific gravity testing requirements.
Various types of metal mesh include:
Expanded wire mesh, also known as expanded metal mesh or expanded sheet metal, is created by feeding metal sheets into an expanding machine, which simultaneously cuts and stretches the sheets to form a patterned mesh. This manufacturing process results in mesh panels with uniformly shaped diamond or hexagonal holes, providing a strong, robust, and consistent structure ideal for a variety of industrial and architectural uses. The final expanded wire mesh product is known for being heavy-duty, durable, and versatile in applications.
Expanded wire mesh is available in different forms and metals, such as carbon steel, stainless steel, and aluminum. These meshes are easy to weld, corrosion-resistant, and feature a long service life. Compared to perforated metals, expanded mesh provides superior airflow and ventilation, making it especially suitable for applications where cooling or thermal regulation is important. Thanks to its affordability, lightweight design, high strength-to-weight ratio, and minimal waste during manufacturing, expanded metal mesh is a popular choice for security fencing, walkways, machine guards, grating, screens, and more.
Woven wire mesh, sometimes referred to as wire cloth or woven wire fabric, features a precise pattern of intersecting metal wires created by fabric-like weaving. Typically, robust wire sheets are formed by interlacing wires over and under perpendicular wires, a method known as Plain Weave Mesh. For applications requiring greater flexibility, a Twill Weave pattern is available, where wires cross over two parallel wires, then under the next pair, resulting in a more pliable and drapable sheet.
Manufacturing woven wire mesh involves feeding wires into automated loom-like devices that weave a straight wire according to the desired wire diameter and opening size. After each layer, wires are woven through the pattern until the mesh reaches the specified length and width, then trimmed to finished size.
Woven wire mesh is available in various mesh counts, wire gauges, and opening sizes, serving widely in filtration, sieving, screening, and separation applications across industries such as mining, food processing, chemical processing, and pharmaceuticals. Its customizable nature, high strength, and excellent dimensional stability make it a staple in both industrial and decorative projects.
Welded wire mesh, also called welded mesh panels or welded wire fabric, is created using advanced welding equipment to join steel wires at precise intersections. This process forms a strong grid pattern where horizontal and vertical wires meet at 90-degree angles.
First, a set of parallel stainless steel, galvanized steel, or carbon steel wires is fed into the machine, followed by perpendicular wires. The machine uses electrical resistance welding to fix each intersection securely, ensuring high strength and uniformity. The process is repeated with additional wires until the roll or panel reaches specified dimensions, then the mesh is cut or rolled as required.
Mechanical Positioning — Cut wires are arranged horizontally across wires drawn from spools, forming right angles. Once properly aligned, the automated welding process starts—producing mesh with consistent dimensions and quality.
Final Steps — After welding, welded wire mesh is rolled or cut into sheets to create mesh panels. These mesh sheets are then stacked or further processed for use in fencing, concrete reinforcement, animal cages, safety guards, infill panels, and more. Compared to woven wire mesh, welded mesh is heavier, has greater structural integrity, and is available in a wide range of wire gauges and mesh sizes to suit commercial and industrial purposes.
To create a more robust protective barrier, a vinyl or PVC coating is applied over welded or woven wire mesh. This vinyl-coated wire mesh, also known as PVC coated wire mesh, enhances resistance to impacts, scratches, abrasions, and harsh weather conditions while maintaining flexibility over a broad temperature range.
Often referred to as plastic mesh due to its vinyl coating, this wire mesh is both durable and attractive, with excellent resistance to rust, corrosion, and UV radiation. The vinyl layer adds a smooth finish and is available in various colors for commercial, residential, and agricultural fencing, garden trellises, animal enclosures, and more. The coating also protects the base metal wire from environmental factors such as moisture and chemicals, extending the lifespan of the mesh even in outdoor and marine environments.
Galvanized wire mesh is produced from carbon steel wire or raw steel wire that is protected with a zinc coating through hot-dip galvanizing or electro-galvanizing. This zinc barrier provides exceptional corrosion resistance and rust protection, making galvanized mesh suitable for outdoor and harsh environments.
Galvanized wire mesh can be manufactured as woven or welded mesh—galvanized after weaving or welding to ensure maximum durability. This type of mesh is widely used in industrial and commercial settings, including window guards, infill panels, greenhouse and garden fencing, agricultural livestock fencing, perimeter and construction fencing, and security barriers. Its affordability and low maintenance requirements make galvanized mesh one of the most popular wire mesh varieties for long-term outdoor use, especially where exposure to moisture or chemicals is likely.
Stainless steel wire mesh stands out for its superior corrosion resistance, strength, and longevity, and incorporates all the advantages of stainless steel alloys. Unlike standard steel, stainless steel resists rust even when exposed to moisture or harsh chemicals, thanks to the addition of chromium and other alloying elements. This ensures lasting protection against oxidation and staining.
Wire mesh made from stainless steel is favored for high-performance industrial applications where durability is crucial, such as in oil and gas processing, marine environments, food and beverage production, chemical processing, water treatment, and pharmaceutical filtration. The mesh can be fabricated using welded or woven construction, depending on specific project requirements.

Stainless steel wire mesh is available in key grades like 304, 316, and 316L, offering a range of mesh opening sizes, wire diameters, and surface finishes to suit fine filtration, heavy-duty screening, decorative panels, or architectural applications. Grade 316 stainless offers outstanding resistance to acids, saltwater, seawater, and chloride environments, making it essential for coastal or marine use. While grade 304 stainless is more affordable and easy to form, 316 provides higher corrosion protection. Common uses include safety screens, machine guards, fencing, sieves, infill panels, basket strainers, and architectural cladding.
Wire netting, sometimes called hexagonal wire mesh, chicken wire, or wire fencing net, is a versatile mesh structure characterized by its woven, usually hexagonal or rectangular, pattern. Wire netting is commonly used for perimeter fencing, aviaries, garden enclosures, and agricultural barriers to protect crops, livestock, and property. In forestry and agriculture, hexagonal netting helps fence woodland areas and prevents animal intrusion, while rectangular netting is used for general property enclosures.
Wire netting also serves critical roles in erosion control, slope reinforcement, avalanche protection, and rockfall barriers due to its ability to absorb and contain loose debris. Specialized types, such as circular braids, are used for shielding cables from electromagnetic interference and reinforcing hoses or industrial tubing. Durable, flexible, and rust-resistant, wire netting is a cost-effective solution for both residential and commercial security fencing, landscaping, and infrastructure projects.
Choosing the Right Metal Mesh for Your Application
Selecting the optimal metal mesh type—whether expanded metal, welded mesh panels, woven wire cloth, galvanized mesh, stainless steel mesh, or vinyl-coated fencing—depends largely on your specific project’s requirements, desired strength, exposure to weather, security level, and aesthetic preferences. By understanding the differences between these mesh types, end-users can make informed decisions for mesh fencing systems, filtration and separation equipment, architectural screens, and industrial safety barriers. To ensure maximum performance, always consider critical factors such as mesh opening size, wire gauge, coating or finish, and compliance with relevant industry standards and specifications.
This chapter provides a comprehensive overview of the primary materials used to fabricate metal mesh, as well as the variety of mesh patterns designed to meet different industrial requirements and applications.
Wire mesh, also referred to as wire cloth or wire fabric, is typically constructed from a selection of ferrous and non-ferrous metals, chosen for their specific mechanical and chemical properties. These base materials are drawn into wires of various gauges—wire thickness measurements essential in determining mesh strength, flexibility, and durability. A lower gauge number corresponds to a thicker, sturdier wire, while a higher gauge indicates finer mesh wires, ideal for filtration or screen applications.
The wire gauge remains consistent for both the shute (weft) and warp (longitudinal) wires in standard mesh types like plain and crimped wire mesh. However, specialty meshes such as Dutch weave wire mesh strategically use different gauges for weft and warp wires to adjust filtration rating and tensile strength. Certain configurations, like stranded wire mesh, utilize bundles of fine gauge wires twisted to achieve maximum flexibility without compromising strength or resistance to deformation.
Wire mesh manufacturing begins by drawing raw metals through precision-engineered dies or draw plates, producing cylindrical, rectangular, square, or even hexagonal shaped wire. The choice of metal, mesh gauge, and wire profile directly impacts product performance, corrosion resistance, electrical conductivity, and suitability for diverse uses—from security fencing and industrial filtration to architectural panels and EMI shielding.
Steel is the most widely used alloy in metal mesh fabrication due to its exceptional strength, ductility, and resistance to wear. Varying the carbon content and thermal processing allows steel to adopt body-centered cubic or face-centered cubic crystalline structures, influencing properties such as tensile strength and flexibility. Stainless steel mesh, including types 304 and 316, offer inherent corrosion resistance, making them ideal for harsh environments, food processing, chemical filtration, construction, and architectural screens.
Elongation, or ductility, is a key mechanical property that allows steel to be drawn into fine wires without fracturing. This ensures steel wire mesh is both robust and versatile for demanding applications, including sieving, sifting, and protective barriers.
Copper wire mesh is recognized for its outstanding thermal and electrical conductivity as well as its impressive flexibility and ease of fabrication. Copper mesh is highly sought-after for electromagnetic shielding, radio frequency interference mitigation (such as in Faraday cages), and as an effective filtration material in chemical and marine settings. Pure copper is rarely used on its own; instead, it's commonly alloyed for enhanced mechanical strength and durability.
Copper wire mesh develops a patina upon exposure to environmental conditions—moisture, salt, and sunlight. This color transformation, ranging from salmon-red to greenish hues (verdigris), can affect aesthetics and performance. For this reason, protective coatings and specialized treatments are often applied to copper mesh to slow or control oxidation, preserving both appearance and conductivity for architectural, industrial, or decorative use.
Bronze mesh is composed primarily of 90% copper and 10% zinc, blending copper’s inherent conductivity with increased hardness and corrosion resistance. Compared to copper wire mesh, bronze offers improved durability and resilience to atmospheric corrosion, making it especially valuable in filtration, seawater-exposed architecture, and industrial screening. Its subtle gold-like appearance also makes bronze mesh ideal for specialty architectural cladding and decorative mesh solutions.
While copper, steel, and bronze are standard materials, specialty wire meshes can be fabricated from advanced alloys such as titanium, Hastelloy, Monel 400, nichrome, Inconel, and tungsten. These high-performance materials provide unique combinations of thermal, chemical, and mechanical properties, allowing wire mesh products to excel in demanding sectors like petrochemicals, aerospace, and laboratory filtration. Virtually any metal that can be wire-drawn may be utilized depending on application-specific requirements.
Aluminum wire mesh is highly valued for its light weight, corrosion resistance, and cost-effectiveness. It is among the most commonly used non-ferrous metals in mesh production. Although grade (pure aluminum) is seldom utilized, aluminum mesh is typically crafted from alloys—such as , , and —to achieve increased tensile strength, rigidity, and impact resistance. Aluminum mesh is frequently employed in insect screens, HVAC duct screens, filtration elements, and architectural applications. Its non-magnetic nature and resistance to rust make it a preferred choice in electrical shielding mesh as well.
Brass wire mesh—produced from copper and zinc alloys such as 270 yellow brass and 260 high brass—features high tensile strength, excellent machinability, and corrosion resistance. 270 yellow brass (65% copper, 35% zinc) and 260 high brass (70% copper, 30% zinc) are selected for their enhanced strength and unique golden color. Brass mesh is often used where both decorative appeal and functional strength are required, including interior design, insect screening, filtration, acoustic panels, and architectural facades. Its abrasion resistance and distinctive coloration make it well suited for both utilitarian and aesthetic wire mesh applications.
Choosing the right metal mesh pattern is vital to achieving the desired balance of strength, aperture size, airflow, and filtration capability. The following are the most common types of mesh patterns found in the wire mesh industry:
The twill weave mesh pattern excels at accommodating thicker and larger diameter wires, making it optimal for heavy-duty filtration and high-strength screening applications. This design alternates warp wires over and under two weft wires, creating a staggered, visually distinctive diagonal line pattern. The interlocking structure provides enhanced rigidity and support, minimizing deformation under load.
Thanks to its superior load-bearing capacity and fine apertures, twill woven wire mesh is widely used in the production of industrial filters, oil and gas filtration, sieving, colanders, process screening, and protective covers. Stainless steel grades 304 and 316 are typically selected for their enhanced chemical resistance and suitability in demanding filtration environments.
Crimped wire mesh is engineered for strength and durability, commonly used in mining, quarrying, security fencing, and industrial sifting. Manufactured using crimping mesh machines, these patterns feature wires that are pre-crimped before weaving, producing interlocking square or rectangular mesh structures. The crimping process ensures consistent aperture sizes, increased rigidity, and long-lasting stability.
Pre-crimped weaves involve crimping both warp and weft wires prior to weaving, generating small ridges that bolster mechanical strength and resistance to movement. This method delivers exceptional structural integrity, making pre-crimped mesh ideal for grilles, baskets, and vibration sieves.
Lock crimp mesh secures the wire intersections at the points formed by pre-crimping. The result is a robust, dimensionally stable mesh suitable for applications demanding resistance to abrasion and shifting under high stress—such as heavy-duty fencing and screening panels.
The inter-crimp style offers additional crimps between crossings, using fine wire and large apertures. This pattern is commonly specified for architectural metal mesh panels, decorative infill, and open-air screening, where both aesthetics and structural support are paramount.
Non-crimped wire mesh, also known as plain weave wire mesh, features a basic over-under weaving pattern. The smooth, uniform surface and high mesh count make it a staple for applications requiring precision screening, such as laboratory mesh, window screens, screen doors, and fine filtration. Its simplicity facilitates consistent mesh openings and efficient fabrication.
Flat top weave wire mesh is designed for maximum durability and minimal surface irregularity. By employing crimped weft wires combined with straight warp wires, this pattern eliminates wire protrusions and enhances abrasive performance. Its smooth, low-flow-resistance surface makes it an excellent choice for architectural facades, structural mesh screens, and high-capacity vibrating sieves found in aggregate processing or bulk material handling operations.
Dutch weave wire mesh, offering both plain and twill variations, is engineered for specialized filtration. The distinctive structure uses finer diameter weft wires paired with coarser, load-bearing warp wires, optimizing flow rate and filtration efficiency in industrial filters and sieves. This configuration yields a dense mesh with very small openings, ideal for precise particle retention in chemical, pharmaceutical, and food processing industries.
Plain Dutch weave wire mesh combines a simple plain weave with the Dutch technique to achieve mechanical stability and fine filtration. It is preferred for applications involving pressure filtration, hydraulics, fuel lines, and gas diffusion where mechanical support and precise control over particle size are required.
Twill Dutch weave wire mesh employs both Dutch and twill weave characteristics, supporting heavy loads while enabling fine filtration. Its construction allows for both robust support and extremely fine separation, making it suitable for high-pressure filter elements and sensitive laboratory testing.
Reverse Dutch woven wire mesh reverses the structure of a standard Dutch weave, featuring closely spaced, robust warp wires with heavier weft wires. This enhances mechanical strength, acoustic properties, and longevity in challenging filtration or separation tasks, such as dewatering, tailings management, and sound attenuation.
Wire mesh edges play an important role in ensuring mesh stability, usability, and safety. Edges can be categorized as raw—the standard edge type where the weft wires remain exposed—and selvage, which features a finished looped border for added durability. Selvage edges help prevent unraveling and provide safer handling in fields such as fencing, industrial screening, and architectural mesh installation. The choice of edge type is determined by the mesh's end use and installation requirements.
When sourcing metal mesh, it’s essential to consider not only material type and pattern, but also specification details such as mesh count, wire diameter, opening size (aperture), and open area percentage. These mesh specifications directly influence performance attributes, including:
Manufacturers offer an array of custom wire mesh solutions, including welded wire mesh (where wires are joined at junctions for added strength), expanded metal mesh (formed by stretching and slitting metal sheets for a one-piece mesh with no welds), and perforated metal sheets (pre-punched with patterns of holes). Choosing the right combination of mesh material, weave type, pattern, and edge treatment is crucial for maximizing product lifespan and efficiency in specific industrial, architectural, or commercial mesh applications.
To obtain the best value and performance from metal mesh, it is advisable to consult detailed technical specifications, sample mesh charts, and, where applicable, request engineering support from trusted mesh manufacturers who can provide custom solutions for filtration, security, design, or separation needs. The correct selection and sourcing procedure ensures compliance with industry standards and enhances the overall efficiency and safety of your project or product.
This chapter will explore the advantages and uses of metal mesh.
Two- or three-dimensional structures made of two or more metallic wires joined by a number of methods are called "wire meshes." Wire mesh items are frequently used for carrying, displaying, fencing, and armoring in various environments. Thus, wire mesh is an essential part of both industry and everyday life.
Stainless steel, galvanized steel, plain carbon steel, aluminum, copper, bronze, brass, and other specialty metals are among the substances used to make metal mesh sheets. To create parallel rows and crossing columns that are roughly similar in size, wires of various thicknesses are braided, entangled, or connected together.
Before deciding on an application, it is vital to understand the metal mesh type and pattern, including the type of wire.
