This Article takes an In-depth look at Wire Mesh
You will learn more about topics such as:
Wire mesh is fabricated by the intertwining, weaving, or welding of wires of various thicknesses to create proportionally equal parallel rows and intersecting columns. Also known as wire fabric, wire cloth, or hardware mesh, the production of wire mesh involves the weaving of wire on industrial looms, leaving square or rectangular gaps between the wires. Welded wire mesh or fabric is manufactured using an electric welder that joins parallel longitudinal wires where the wires intersect.
There are a limitless number of shapes, sizes, and configurations of wire mesh made from an assortment of highly durable and resilient materials whose major function is to separate, screen, structure, and shield various applications and processes. The types of wire include galvanized steel, stainless steel, aluminum, steel, and copper alloy wire. The type of application, necessary tensile strength, durability, longevity, and required flexibility are some of the factors used to determine the desired type and style of wire.
The processes used to produce wire mesh are weaving and welding, with wire weaving being similar to the weaving of cloth on a loom, while welding is used to join the wires where they intersect. Both processes are completed using pre-programmed machines.
Near the end of the 17th century, woven wire cloth for the mining and pulp industries came into high demand, leading to the development of wire weaving looms. Over the centuries, the use for wire mesh has advanced beyond mines and pulp mills to architecture, plastic extrusion, aggregate screening, and filtration processing. The rise in demand has led to the modern industrial wire weaving industry.
Weaving Loom &#; Weaving looms weave mesh rolls with widths of 48&#;, 60&#;, 72&#;, 98&#;, or wider. The loom has a warp beam, heddle frames, a reed, a rapier for transporting weft wire, and a take-up mechanism.
Manufacturers use looms to weave meshes of standard and custom patterns. The completed mesh rolls are cut to varying lengths depending on the needs of customer specifications. Wires woven horizontally or lengthwise are warp wires, while wires woven vertically or crosswise are referred to as weft wires or shute wires, terms commonly used in textile manufacturing.
Once the loom has been assembled and the warp beam loaded, the weaving process is completed automatically. As the loom begins, the warp beam unwinds in slow, even increments. In unison with the warp beam feeding the warp wire, the take-up mechanism winds the woven completed cloth in the same increments as the warp beam. The synchronized motion helps the loom maintain tension on the warp wires, which is a critical necessity for the production of high-quality cloth.
Wire mesh is welded using a semi-automatic process that welds the intersections of the woven wires. Welding machines are programmed to weld the intersections at the horizontal and vertical aligned wires. Several welding techniques are used to join the connections, including resistance welding, tungsten inert gas (TIG) welding, plasma welding, and soldering.
Welded mesh is heavier, sturdier, and stronger than woven wire mesh and can only be used with thicker wires that are capable of withstanding the welding process. Since the wire is welded, it is more rigid and durable, which makes it ideal for fencing, cages, and concrete mesh sheets.
The different kinds of wire mesh are classified by how they were made, their qualities, function, and weave patterns. Each of the various types is designed to meet the strength, weight, and finish requirements of a project or application. The determining factors regarding the type of wire mesh that will be used are its finish, type of metal, and type of pattern, with finish and metal being the major determining factors.
Welded wire mesh has square-shaped wire patterns. The welding process forms a strong mesh, which makes it perfect for security fencing, storage and racking in warehouses, storage lockers, animal holding areas in veterinary clinics and animal shelters, room divisions, and traps for pests.
Welded wire mesh is:
When welded wire mesh is made from stainless steel, it has stainless steel&#;s durability and corrosion resistance.
Galvanized wire mesh is made from plain or carbon steel wire that is galvanized, a process that involves applying a zinc coating. The zinc layer acts as a shield that protects the wire mesh against rust and corrosion. Galvanized wire mesh can be welded or woven using galvanized wire or plain steel wire that is galvanized after being woven or welded. Of the two processes, galvanizing the wire mesh after it is processed initially costs more but produces a higher-quality wire mesh.
Galvanized wire mesh is ideal for fencing for agriculture and gardening, greenhouse, architecture, building and construction, security, window guards, and infill panels. Due to its cost, it is one of the more widely used of the different types of wire mesh.
The application of a vinyl coating to welded or woven wire mesh creates a strong barrier for very flexible wire mesh. Vinyl-coated wire mesh is stable over a wide range of temperatures, is not degraded by exposure to the sun, and is resistant to scrapes, abrasions, and impact.
The vinyl coating of wire mesh gives the impression that the mesh is made of plastic and is sometimes referred to as plastic mesh. Aside from giving wire mesh an appealing appearance, vinyl-coated wire mesh is long-lasting, durable, and rust- and corrosion-resistant. It seals the wires from water and other intrusive elements.
Welded steel bar gratings are produced by forge welding at extremely high temperatures. In this process, perpendicular bars are drawn across a parallel series of rectangular bars, connecting the bars together. The process creates a fused, long-lasting connection that can withstand the most demanding and hazardous conditions. The steel for welded steel bar gratings is carbon steel or stainless steel and is exceptionally durable, strong, and rigid.
Designed to carry heavy workloads for many years, welded steel bar grating is used for landing mats, bridge decking, ventilation grills, ramps, sidewalks, and industrial flooring. Panels are produced in two to three-foot widths in two-foot lengths in a wide range of bar sizes, from 1&#; to 6&#; depths and 0.25&#; up to 0.50&#; thicknesses.
Stainless steel wire mesh has all of the positive properties of stainless steel and provides high-quality protection and performance. Steel is widely used to produce wire mesh but rusts easily when exposed to the air. Stainless steel, which has the same compounds as steel, has chromium added that is rust-resistant and protects stainless steel from oxidation.
In wire mesh manufacturing, stainless steel is known for its reliability, sturdiness, and durability. The rust resistance of stainless steel makes it adaptable to any outdoor application. It consistently delivers strength and longevity, making it the most popular wire mesh form.
As with all forms of wire mesh, stainless steel can be welded or woven. The grades of stainless steel used to produce wire mesh are 304, 304L, 316, 316L, 321, 347, or 430 in wire diameters ranging from 0. inch (0.216 mm) up to 0.307 inch (7.8 mm). The openings of wire mesh change in accordance with the type of wire mesh. Openings that are less than 0.25 inch (6.35 mm) are classified as wire cloth. Critical factors for wire mesh are the percent of the open area and the weight of the mesh.
Grade 316 stainless steel is a premium alloy that is used for marine applications. It has exceptional corrosion resistance and is not affected by acids, salt water, or seawater, and comes in fine, medium, or coarse sizes. Stainless steel grade 304 is not as corrosion resistant as grade 316 but is exceptionally workable and less expensive than grade 316.
The pattern of wire mesh determines its capacity and how it can be used. There are an endless number of standard weave patterns and customized ones designed to fit a specific application. One distinction between the various patterns is whether the wire is crimped or not crimped, with crimping mechanically changing the contour of the weft or warp wires.
Crimped wire mesh is a square or rectangular weave that is woven using a crimping mesh machine. The processes used to produce crimped wire mesh involve compressing the wire such that the weft wire wraps over the warp wire and the warp wire wraps over the weft wire. The crimping process produces a bending effect on the wires such that they wrap over each other.
Non-crimped wire refers to plain wire mesh where the wire mesh is formed by a simple over-under weave of the warp and weft wires. The final product has a simple appearance with a smooth, even surface. Traditionally, non-crimped wire or plain wire has a higher mesh count.
Plain weave wire mesh is the most common of the wire mesh products. Wire mesh that has a 3 x 3 or finer wave has a plain weave pattern. It is commonly used for screening, such as screen doors and window screens.
Double weave wire mesh is a variation of the pre-crimped weave pattern. In the weaving process, the warp wires pass over and under two weft wires to form a wire mesh pattern capable of withstanding stressful and demanding uses. The double weave wire mesh pattern produces a wire mesh with extra durability for supporting vibrating screens in mining operations and crushers, fences for farming, and screens for barbecue pits.
Flat top weave has non-crimped warp wires and crimped weft wires that create a sturdy, lockable wire mesh with a flat surface. It has a long abrasive life since no wires project from the top of the mesh to wear. Flat top weave wire mesh has little flow resistance, making it popular for architectural and structural applications requiring a smooth surface. A common application for flat top weaves is for vibrating screens.
The twill weave pattern is ideal for weaving heavier and larger diameter wires. The pattern is formed by weaving warp wires over and under two weft wires or where a weft wire passes over and under two warp wires. The warp wire is inverted at the intersections to create a highly stable, rigid, and strong wire mesh. As the pattern develops, it becomes staggered, giving an appearance of parallel diagonal lines.
Twill weave wire mesh can support heavier loads and perform fine filtering. It is a basic component of the production of filters, colanders for aliments, chemical production, shielding, and mosquito nets. For filtering processes, it is made of stainless steel grades 304 and 316 due to their resistance to acids and wear.
Dutch weave is different from plain weave wire mesh and twill weave wire mesh. In dutch weave wire mesh, the weft wires have a different diameter than the warp wires, with the warp wires being coarser to supply greater tensile strength. Weft wires are finer with smaller diameters to enhance filtering performance. The increased strength and finer openings make dutch weave wire mesh popular as a filtering cloth.
The dutch weaving process can be plain or twill, each of which has individual characteristics to fit the needs of different applications.
Plain Dutch Weave Wire Mesh &#; Plain dutch weave combines the dutch weave process with plain wire weave. Using two different diameter wires, the coarse warp wire passes over and under the weft wire while the weft wire passes over and under the warp wire. The main advantages of plain dutch weave wire mesh are mechanical stability, finer wire openings, and exceptionally high tensile strength.
Twill Dutch Weave Wire Mesh &#; Twill dutch weave is a combination of regular twill weave and dutch weave. The weft wire alternately passes over and under two warp wires creating a fine mesh in the direction of the warp wire, with the warp wires forming a coarser mesh in the same weave. Twill dutch weave is superior to normal twill weave due to the finer openings and the ability to support heavier loads for filtering applications.
The advantages of twill dutch weave wire mesh are its better filtering potential, tensile strength, the ability to filter exceptionally fine materials, and its stability.

Featured content:Off count wire mesh refers to wire mesh that does not have the same mesh count in both directions creating a rectangular rather than square mesh pattern. It is used in sifting and sizing operations to increase productivity and also where slight inaccuracies are not an issue.
Stranded weave wire mesh uses small-diameter weft and warp wire bunches that are woven in a plain square pattern. The use of multiple wires creates a twill style pattern that is extremely tight and strong. The tightness and density of the weave are useful in microfiltration cloth.
The term mesh count refers to one of the most important principles of the wire mesh manufacturing industry. It is in regard to the number of openings per linear inch in wire mesh. The mesh count is determined by counting the number of openings in one linear inch from the center wire of a wire mesh. It is expressed as a single digit, such as no. 4 for a 4 by 4 mesh or no. 20 for a 20 by 20 mesh. The number is an indication of the number of openings in one linear inch.
The two forms of wire mesh edges are raw and selvage. When wire mesh cloth is woven, the weft wires form an edge along the length of the roll and prevent the mesh from unraveling. In the case of a raw edge, those weft wires are uncovered at the edge of the wire mesh.
With selvage edge wire mesh, the border of the wire mesh is finished to increase the stability of the mesh and protect workers when handling the mesh. There are various methods for creating selvage edges, including looping the wires at the edge of the cloth.
The raw material for wire mesh is its wire, which is made from several types of ferrous and non-ferrous metals. The wire used to produce wire mesh comes in various gauges, which is a numerical representation of the thickness of a wire. In gauge numbering, lower numbers represent thicker wires while higher numbers signify thinner wires.
For plain and crimped wire, the gauge of wire is the same for the shute or weft wires as it is for the wrap wires. With dutch woven wire, the weft and warp wires have different gauges. The bundles for stranded wire mesh consist of very small gauge wires that have been twisted together.
Aside from the gauge of wire, the metals used to make the wire determine the type of wire mesh and its use. Wire for wire mesh is made by drawing raw metal through a die or draw plate. The majority of wires used to make wire mesh are cylindrical, with square, hexagonal, and rectangular also used.
Carbon plain steel is one of the more popular metal wires used to manufacture wire mesh. It is mainly iron with a small amount of carbon and is a low-cost, versatile metal used for window guards, screens, and separation screens for mining. Carbon steel can be zinc coated to make galvanized steel wire or powder coated with plastic.
Stainless steel wire mesh is exceptionally strong and durable with an appealing shiny luster for use in architectural applications. Many stainless steel grades are used in the manufacture of wire mesh, with grades 316 and 304 being the most common.
Aluminum is lightweight, flexible, malleable, corrosion-resistant, and low priced. It is the most popular of the non-ferrous metals used to produce wire mesh. Aluminum grade , pure aluminum, is seldom used to produce aluminum wire mesh. The majority of aluminum is alloyed with other metals such as copper, magnesium, zinc, or silicon in certain percentages to increase the strength of aluminum as well as improve some of its other properties.
Alloys , , and are the most commonly used for the production of aluminum wire mesh.

RemainderCopper wire mesh is ductile and malleable, with exceptional thermal and electrical conductivity. It is often used for radio frequency interference shields in Faraday cages and electrical applications. As with aluminum, copper is seldom used in its pure form and is usually alloyed to enhance and improve its natural properties.
Copper changes color when exposed to salt, moisture, and sunlight, from salmon-red to shades of brown to gray and, finally, blue-green or gray-green. To avoid the change in the color of copper wire mesh, it is treated with coatings and chemicals, which speeds up or slows down the oxidation process.
Brass is an alloy of copper and zinc. It is a soft, pliable metal known as 270 yellow brass or 260 high brass in wire mesh manufacturing. The chemical composition of 270 yellow brass is 65% copper and 35% zinc. With 260 high brass, the chemical composition is 70% copper and 30% zinc. The increased content of zinc in brass wire mesh gives it high tensile strength and abrasion resistance and produces hardened mesh.
Industrial grade brass wire mesh has a yellow tint that makes it popular as a decorative artistic addition to architectural projects.
Bronze is also an alloy of copper that consists of 90% copper and 10% zinc. It has the same properties as copper, including malleability, ductility, and durability. Bronze has a higher resistance to corrosion than brass and is harder and less malleable than copper. It is used for industrial applications such as filtering and architectural applications.
The alloys and metals listed above are the more popular types of wire used to produce wire mesh. Other metals that are used for custom wire mesh are titanium, Hastelloy, Monel 400, nichrome, Inconel, and tungsten. Essentially, any ferrous or non-ferrous metal that can be formed into a wire can be used to produce wire mesh.
There are endless uses for wire mesh patterns because they are adaptable and can meet any requirements. Industrial uses for wire mesh are as protective shielding, parts of filtration and separation systems, and railing supports. Wire mesh is the primary part of filtration systems in wastewater treatment plants, petrochemical facilities, and juice production.
Aside from its industrial use, wire mesh has had commercial uses for many years as protection against insects and as parts of animal enclosures. Screen doors, window screens, screen partitions, and decorative screens are produced using various forms of wire mesh.
Industries that rely on wire mesh are:
Commercial and residential uses for wire mesh include:
You have plenty of options when it comes to sectioning off or securing an area. But woven wire mesh partitions offer many benefits that other materials simply lack.
For example, our one-and-a-half-inch diamond mesh partitions are securely interwoven, double crimped, durable products. We clinch our partitions on drawn metal frames, making them stronger. We can make our partitions in a variety of sizes to fit your needs.
Here are some specific reasons you may want to consider woven wire mesh partitions for your next project.
Guaranteed Ventilation
Woven wire mesh partitions are an excellent choice if what you&#;re securing requires ventilation.
For example, a woven wire mesh is the best option if you want to secure your company&#;s servers. That&#;s what Jesco Industries used when a large Midwestern data center approached us for a security solution. Keeping your servers cool is crucial to keeping both your data and your property safe.
Better Visibility
If you&#;re securing something, it&#;s because it&#;s valuable to you or your company. Woven wire mesh partitions let you keep your eyes on your property while still keeping it safe and secure.
Better visibility is also invaluable in situations where you want to use a partition to increase people&#;s safety. For example, when Nokomis Middle School in Newport, Maine, wanted to secure a stairwell, they didn&#;t just want to put up a wall that would allow students or visitors to walk around unseen. By using woven wire mesh, Nokomis Middle School was able to keep their stairwell well-lit and within view of teachers and staff without sacrificing on security.
Fire Prevention
When the worst happens, you&#;ll want to make sure you chose the best materials to secure your property. Woven wire mesh partitions are fireproof. They also, simply due to the nature of their construction, provide firefighters the ability to hose spray your property even if the partitions themselves remain locked.
Cost-Effective and Secure
Our partitions are made out of woven wire mesh, resulting in a pattern of geometric spaces between the wires. Because of this, they automatically use less materials to construct than a partition made out of something completely solid. That means you get the durability and security of a solid partition for a fraction of the cost.
Using mesh also decreases other related costs. Do you want to spend extra money fitting a secure space with video cameras and microphones to make sure you can see and hear what&#;s going on at all times? Woven wire mesh partitions allow you to skip the intense security installation and instead rely on your eyes and ears to protect your property.
You don&#;t have to compromise on cost just to get the security you need. If you do have greater security concerns, our high security wire systems are heavy-duty products that can give you peace of mind.
