Chapter 1: Principle of Metal Mesh

This chapter will discuss what metal mesh is, how it is made, and the design considerations.

What is Metal Mesh?

The phrase "wire mesh" describes two- or three-dimensional structures constructed of two or more metallic wires connected by various techniques. In a wide range of settings, wire mesh products are frequently used for carrying, displaying, fencing, and armoring. As a result, wire mesh is a necessary component of both industry and daily life.

The materials used to create metal mesh sheets include stainless steel, galvanized steel, plain carbon steel, aluminum, copper, bronze, brass, and other specialty metals. Wires of different thicknesses are intertwined, woven, or joined to form parallel rows and intersecting columns that are proportionately equal in size.

The process of creating wire mesh (sometimes referred to as wire fabric, wire cloth, or hardware mesh) entails weaving wire on commercial looms while leaving square or rectangular gaps between the wires. An electric welder is used to join parallel longitudinal wires where they intersect to create welded wire mesh or cloth.

How Metal Mesh is Made

Iron is used to make steel, which has unique and desirable properties. In particular, stainless steel is entirely rust-resistant and extremely durable, making it the ideal choice for a variety of functions in the economy. Steel wires are more useful for creating wire mesh and other products due to their excellent ductile (the ability to be formed into wires) quality combined with their tensile strength and flexibility.

Wire mesh is one of the earliest and most straightforward things made from steel. Steel wire mesh has been used for millennia in one form or another. The world's social economies, which are constantly expanding, have discovered new applications, such as fencing and barricading, safety covers for operating machines, cages, grills, sifters, and shelves.

Iron welded wire mesh is used as concrete reinforcement, which serves another significant purpose. Steel wire maker firms cater to the secondary level ancillaries that utilize these wires to create the mesh through welding or weaving.

Design Considerations for Metal Mesh

• Important characteristics of the mesh, including spacing, opening size, and mesh count, are often determined by the application. Wire cloth is determined by mesh size in some applications and opening size in others.
• The difference between woven and welded construction has the biggest effect on the toughness and durability of metal cloth, with welded wire cloth having the best qualities.
• The weaving affects the strength and durability of different types of woven wire fabric.
• The working environment (temperature, humidity, wet vs. dry, flames, marine salt spray) determines the choice of metal or metal alloy.
• The material is also informed by the media that is processed (wet slurries, dry non-corrosive powders, acids, corrosive chemicals).
• One of the most important characteristics of wire cloth is the diameter of round wire, the width of flat wire, or the breadth of ribbon. Even though several distinct wire gauge systems are in use, some wire cloth manufacturers may define wire size in terms of "wire gauge" size. To avoid confusion, the wire diameter should be calculated using a numerical inch or micron value.
• The number of wires over a unit length, typically a linear inch, measures the mesh size, also known as the wire count or mesh count. The mesh count is calculated from wire center to wire center. The size of very big aperture wire mesh fabric is determined by the space between the two adjacent wires; examples are 1-inch mesh, 2-inch mesh, 58-inch mesh, etc.

Considerations when Choosing Metal Mesh (or Wire Cloth)

The considerations include:

Temperature

Understanding temperature limits is crucial when using a fireproof wire mesh in high-temperature applications. Given that any malleable metal or alloy can be used to create woven wire mesh, you should select the best one for a particular procedure. Here are some of the highest working temperatures: stainless steel grade 304 ( °F or 815.5°C); Inconel (°F or 982°C); nickel (°F or °C); and tungsten (°F or °C).

Corrosive Effects

Although most wire cloths are prone to corrosion, some materials, including titanium and alloys like Hastelloy, Inconel, and Nichrome, can tolerate more corrosive conditions.

Viscosity

Viscosity is crucial in wastewater treatment, oil handling, and other petrochemical filtering. Filters can handle thinner, less dense fluids more quickly. Consider what kind and size of wire mesh are required to process very viscous materials to get the best outcomes. Viscosity frequently has a direct relationship with temperature.

Particulate Matter Size

Particle size is an obvious factor to consider when selecting the ideal wire mesh. The mesh count, aperture size, and wire diameter can all be determined using the size of any retained particles. It is important to purchase test sieves to achieve the requirements for retained particulate matter sizes.

Pressure Drop Requirements

When materials pass through a filter, the pressure decreases and impurities are eliminated. The filter media you select for your filter significantly impacts the pressure drop rate. The filter will eventually need to be replaced when the pressure decrease reaches a certain level. Effective wire mesh solutions that match your pressure drop criteria decrease costs and contamination hazards.

Flow Rates

Viscosity, pressure drop, and flow rate are closely connected. You should consider the percentage of open area when choosing the appropriate mesh product for procedures that specify a required flow rate.

Contaminant Types

Certain pollutants will influence the material to be utilized, the wire diameter, the density of the wire mesh, the tolerance, the opening size, and the type of weave.

Specific Gravity

Depending on the purpose, wire cloth parameters must frequently be adjusted. Wire cloth mesh baskets and sieves are used for numerous manufacturing processes to gauge and test the specific gravity of a filtered material. These items, which are often made of brass or stainless steel, must be ordered in accordance with your particular gravity testing requirements.

Chapter 2: Types of Metal Mesh

The different types of metal mesh include:

Expanded Wire Mesh

Expanded wire mesh is made by placing metal sheets in an expanding machine that cuts the pattern of the wire mesh into the sheets and spreads or expands the pattern. The uniform contour of the holes creates a strong, sturdy, and uniform mesh. The process produces a heavy duty and durable wire mesh.

The various forms of expanded wire mesh are easy to weld and have a long lifetime of use. Unlike perforated metals, expanded wire mesh allows for more airflow, which makes it ideal for projects that need thermal regulation. It is also widely used due to its low cost, lightweight, and the small amount of waste produced during production.

Weaved Wire Mesh

The array of intersecting wires in woven wire mesh resembles the weave of a fabric. Usually, a sturdy sheet is created by weaving the wires over and under the perpendicular wires. Weaved wire mesh is also known as Plain Weave Mesh. A "Twill Weave" can be utilized in applications where a more flexible sheet is needed. This includes weaving wire over two parallel wires, then beneath the following pair of parallel wires, and so on.

Instead, they are fed into a device resembling a loom that weaves a straight wire across the pattern of the user&#;s choice. The next straight wire is then run through the pattern once the wires have been bent in the other direction. The finished wire mesh sheet is then trimmed to the required size after the machine repeats this procedure until the desired dimensions are achieved.

Welded Wire Mesh

Steel welded wire mesh is created using precise, semi-automatic welding equipment. This machine features a chamber that can supply welds at predicted intersections, which in the case of a mesh are the spots where steel wires aligned horizontally and vertically cross.

One alignment of parallel stainless steel welding wire is fed into the machine, followed by another set of parallel wires perpendicular to the first. Then, the machine welds the 90-degree junction of the two wires together.

Electrical resistance is used to produce enough heat to form the weld. Once the welding is complete, another length of the parallel wires is fed into the apparatus to continue the welding. The operation is stopped once the desired length of welded mesh is generated, and the mesh is trimmed to the required dimensions.

Mechanical Positioning &#; Cut wires are laid out level across wires fed from spools. The wires are at right angles and perpendicular to one another during mesh welding. Once the wires are in position, the programmed welding technique begins and performs a uniform weld at each cross-section.

Final Steps &#; after welding, the resulting wire mesh can be rolled up like in wire weaving or cut into the appropriate size sheets that can be stacked in rows to create wire mesh panels. Welded mesh is heavier, more robust, and stronger than woven wire mesh and can only be produced with larger wires that can withstand the welding process.

Vinyl Wire Mesh

A sturdy barrier is made for very flexible wire mesh by applying a vinyl coating to welded or woven wire mesh. Vinyl-coated wire mesh is resistant to impacts, scrapes, and abrasions and maintains stability across a wide temperature range.

Wire mesh is sometimes referred to as plastic mesh because of the vinyl covering that gives the appearance that the mesh is composed of plastic. Vinyl-coated wire mesh is resilient, long-lasting, rust- and corrosion-resistant, and has a pleasing look. Furthermore, it protects the wires from contaminating factors like water.

Galvanized Wire Mesh

The raw or carbon steel wire used to create galvanized wire mesh is coated with zinc during the galvanizing process. The zinc layer serves as a shield to prevent corrosion and rust on the wire mesh. Galvanized wire or plain steel wire that has been woven or welded and then galvanized can be used to create galvanized wire mesh.

Galvanizing the wire mesh after it has been prepared results in a higher-quality wire mesh but costs more than the other two processes. Galvanized wire mesh is perfect for window guards, infill panels, greenhouse fencing, agricultural and gardening fencing, building and construction fencing, and security fencing. It is one of the more often utilized varieties of wire mesh because of its price.

Stainless Steel Wire Mesh

Stainless steel wire mesh offers superior performance and protection and has all the benefits of stainless steel. Wire mesh is frequently made of steel; however, steel rusts quickly when exposed to air. With the addition of chromium, stainless steel, which is made of the same components as steel, is resistant to rust and shielded from oxidation.

Stainless steel is renowned for its dependability, sturdiness, and longevity in producing wire mesh. Any outdoor application can use stainless steel because of its resistance to rust. In addition, its durability and strength make it the most widely used type of wire mesh. Stainless steel can be welded or woven, as with all types of wire mesh. The stainless steel grades used to make wire mesh include 304, 316, and 316L, with wire diameters ranging from 0.22 to 0.105 inches (0.55 to 2.66 mm) and apertures ranging from 0.25 inch to 1 inch (6.35 to 25.4 mm).

For maritime purposes, a superior alloy called grade 316 stainless steel is employed. It is available in fine, medium, or coarse diameters, has great corrosion resistance, and is unaffected by acids, salt water, or seawater. Although grade 304 stainless steel is workable and less expensive than grade 316, it is not as corrosion resistant as grade 316.

Wire Netting

The so-called wire netting fences are one type of wire netting. Examples include the common rectangular nettings used to surround properties. In forestry and agriculture, hexagonal netting is used to fence woodland plantations and safeguard them from animals. Such netting also acts as a slope reinforcement and safeguard against avalanches and rock falls. Another unique category of nettings, circular braids, is used to insulate wires from electromagnetic interference or to reinforce hoses and cables.

Chapter 3: Types of Materials Used to Make Metal Mesh and Mesh Patterns

This chapter will discuss the types of materials used to make metal mesh including the mesh patterns.

Types of Materials Used to Make Metal Mesh

Wire is the primary component of wire mesh and is produced from various ferrous and non-ferrous metals. Wire used to make wire mesh is available in a variety of gauges, which are measurements of a wire's thickness. Lower numbers in gauge numbering indicate larger wires, while higher numbers indicate thinner wires.

The wire gauge for shute or weft wires and warp wires made of plain and crimped wire is the same. The weft and warp wires of dutch weaved wire have various gauges. Very thin gauge wires that have been twisted together make up the bundles for stranded wire mesh.

The type of wire mesh and its application depend on the metals used to form it, in addition to the wire gauge. By pulling raw metal through a die or draw plate, wire for wire mesh is created. In addition to cylinder-shaped wires, rectangular, square, and hexagonal wires are also utilized to produce wire mesh.

Steel

Steel is an alloy of iron and carbon. Depending on the temperature, it can take either the body-centered cubic or the face-centered cubic crystalline forms (allotropic forms). Steel and cast iron have a variety of special qualities that result from the interaction of the iron allotropes with the principal carbon alloying element.

The degree to which a material may be stretched or compressed without breaking is known as the elongation (or ductility). It lies between the tensile and yield strength and is given as a percentage of the length being evaluated (i.e., what percent does the material bend before breaking). This property of steel enables it to be drawn into wires used to make metal mesh.

Copper Wire

Copper wire mesh has exceptional thermal and electrical conductivity and is ductile and bendable. As a result, it is frequently utilized in electrical applications and Faraday cages as a screen against radio frequency interference. Similar to how aluminum is rarely utilized in its pure form, copper is typically alloyed to improve and enhance its inherent qualities.

When copper is subjected to salt, moisture, and sunlight, its color changes from salmon-red to brownish-gray to blue-green or gray-green at the end. Copper wire mesh is coated with coatings and chemicals that either speed up or slow the oxidation process to prevent color change.

Bronze

Bronze is a 90% copper and 10% zinc alloy of copper. It shares several characteristics with copper, including malleability, ductility, and toughness. In addition to being tougher and less pliable than copper, bronze has stronger corrosion resistance than brass. It is utilized in industrial settings for filtering and architectural purposes.

The more common types of wire used to create wire mesh are those made of the alloys and metals mentioned above. Additionally, titanium, Hastelloy, Monel 400, nichrome, Inconel, and tungsten are utilized to create bespoke wire mesh. Basically, wire mesh can be made from any ferrous or non-ferrous metal that can be shaped into a wire.

Aluminum

Aluminum is inexpensive, lightweight, malleable, flexible, and resistant to corrosion. It is the most often used non-ferrous metal for making wire mesh; aluminum grade , or pure aluminum, is rarely used to make aluminum wire mesh. To boost aluminum's strength and enhance some of its other features, most aluminum is alloyed with other metals like copper, magnesium, zinc, or silicon in certain amounts. The three alloys , , and are used most frequently to make aluminum wire mesh.

Brass

How Much Torque Should an Electric Screwdriver Have?

Brass is a copper and zinc alloy. In the production of wire mesh, it is a soft, malleable metal known as 270 yellow brass or 260 high brass. 270 yellow brass is 65% copper and 35% zinc, while the chemical make-up of 260 high brass is 70% copper and 30% zinc. Brass wire mesh has great tensile strength, excellent abrasion resistance, and is toughened due to the higher zinc content. Industrial grade brass wire mesh is a common decorative artistic element in architectural projects because of its yellow hue.

Types of Metal Mesh Patterns

The types of metal mesh patterns include:

Twill Weave

The twill weave pattern is perfect for weaving heavier and larger diameter wires. Warp wires are woven over and under two weft wires to create the pattern or vice versa. The warp wire is reversed at the intersections to produce a highly rigid, strong, and stable wire mesh. The pattern becomes staggered as it grows, giving the impression of parallel diagonal lines.

Wire mesh with a twill weave may filter tiny particles and support greater loads. It is a fundamental part of the manufacturing process for filters, food colanders, chemicals, shields, and mosquito nets. Due to their resistance to acids and wear, stainless steel grades 304 and 316 are used in filtration operations.

Crimped Wire Mesh

A crimping mesh machine is used to weave crimped wire mesh with a square or rectangular weave. Compressing the wire for the warp wire to wrap over the weft wire and vice versa is one of the steps used to create crimped wire mesh. The wires are bent during the crimping process, causing them to wrap around one another.

Pre-Crimp

Pre-crimped weaves are crimped before the wire is woven with the addition of tiny folds or ridges to strengthen the rigidity and strength of the wire mesh. The procedure keeps the weft and warp wires secure and stops them from shifting.

Lock Crimp

This pre-crimping technique locks the weave together at the points where the weft and warp wires connect by using the grooves left over from the crimping process. The final weave is stronger and immovable, similar to pre-crimping.

Inter-Crimp

With inter-crimp, the weft and warp wires are each given a second crimp in between the intersections. This procedure uses fine wire with wide apertures to ensure the weft and warp wires are securely locked to offer more rigidity.

Non-Crimped Wire Mesh

Non-crimped wire is a plain wire mesh made from a straightforward over-under weave of the weft and warp wires. The finished item has a consistent, smooth surface and a simple appearance. Traditionally, plain wire or wire that has not been crimped has a higher mesh count. The most widely used type of wire mesh is plain weave. A plain weave pattern is used in wire mesh with waves that are 3 x 3 or smaller. It is frequently employed for screening purposes, such as window and screen door screens.

Flat Top Weave

Flat top weave produces a strong, locking wire mesh with a flat surface using crimped weft wires and non-crimped warp wires. Since no wires protrude from the top of the mesh to wear, it has a long abrasive life. Due to its low flow resistance, flat top weave wire mesh is preferred for architectural and structural applications requiring a smooth surface. For example, vibrating screens are a typical use for flat top weaves.

Dutch Weave Wire Mesh

Compared to twill weave and plain weave wire mesh, dutch weave is unique. The weft wires of dutch weave wire mesh are a different diameter from the warp wires, which are coarser to provide higher tensile strength. To improve filtering efficacy, weft wires are finer and have smaller diameters. Dutch weave wire mesh is preferred as a filtering material due to its higher strength and smaller openings. Both plain and twill dutch weaving techniques have unique properties to meet the demands of various applications.

Wire mesh with a plain dutch weave has a plain dutch weave mesh that combines a plain wire weave with the dutch weave technique. The weft wire travels over and beneath the coarse warp wire using two different diameter wires, while the reverse is true for the warp wire. Its key benefits are its mechanical stability, smaller wire holes, and extraordinarily high tensile strength of plain dutch weave wire mesh.

Wire mesh with a twill dutch weave pattern combines a standard twill weave pattern with a dutch weave pattern. The weft wire forms a thin mesh in the direction of the warp wire by passing over and under two warp wires alternately, while the warp wires make a coarser mesh in the same weave. Due to its ability to sustain larger loads for filtering purposes and finer apertures than regular twill weave, twill dutch weave is preferable.

Dutch woven wire mesh in reverse is identical to dutch woven wire mesh in plain form. However, with the warp and weft wires switched, the two weaves differ in how the weft and warp are woven. The warp wires have more strength because they are tightly woven with heavier weft wires and positioned close together. Applications requiring wire mesh with acoustic characteristics, mechanical strength, and throughput filtration use the reverse dutch weave.

Metal Mesh Edges

Wire mesh edges come in two different varieties: raw and selvage. The weft wires provide an edge along the length of the roll when weaving wire mesh cloth, preventing the mesh from unraveling. These weft wires are exposed at the edge of the wire mesh in the case of a raw edge.

To strengthen the stability of the mesh and safeguard workers when handling the mesh, selvage edge wire mesh has a completed border. There are several ways to make selvage edges, one of which is to loop the wires at the cloth's edge.

Chapter 4: Benefits and Applications of Metal Mesh

This chapter will discuss the benefits and applications of metal mesh.

Benefits of Metal Mesh

• Wire mesh panels are employed to retain material and carry large weight, which lessens the need for on-site labor.
• Wire mesh panels are flexible and capable of supporting weight, so they can be used to transport raw materials without worrying about them coming undone (and thus being a hazard).
• The risk of damage is decreased by the uniformity with which welded wire mesh panels can bend.
• The variable bar size and spacing approach can provide greater adaptability and be more affordable by allowing users to precisely select the size of reinforcement and gaps required.
• 20% faster construction and transportation times.
• Infrastructure made of concrete is reinforced with it. The idea is to efficiently disperse any internal stress through the exposed sides of the wire mesh panels. If one touches these bars, one will feel the vibrations and stress being released. This benefits construction sites both before and after.
• If the mesh panel needs to be cut, there is no requirement for a rebar yard.
• Handling is automatically safer when bending is simple.
• Wire mesh panels, which are smaller and give far greater crack and stress resistance than a lengthy sheet running throughout the floor or wall, should be used instead of whole wire mesh sheets.
• Metal mesh decreases accident risks, which leads to greater adherence to OSHA regulations.
• Mesh of welded wire steel is used for fencing because it is durable and unyielding. The welded wire mesh is made as resistant to climbing or damage from potential attackers as possible. Additionally, it is resilient enough to survive the impact of heavy trucks and animals without suffering the typical damage that other fence kinds do.
• Installing wire mesh is simple since it is supple and malleable, making it simple to insert or attach to a wall, railing, or other flat surfaces.
• Computers, monitors, and other electronics must be in storage spaces with good ventilation. Thanks to wire mesh, electronics that are delicate and sensitive can be held safely with restricted access.
• Wire mesh can be utilized as dividers between workstations while allowing for simple accessibility. It is simple to remove or rearrange to accommodate shifting organizational dynamics.
• Wire mesh can be used in warehousing to separate products while making them readily identifiable and visible for retrieval. Wire mesh usage eliminates time-consuming inventory checks and searches.

Applications of Metal Mesh

• Wire mesh facades include a series of wire mesh panels that are assembled to form the exterior of a building. The wire mesh panels are installed by being tensioned to the height of the building with support at their top and bottom. Aside from their architectural function, wire mesh panels offer protection from the sun&#;s rays and absorb sound.
• Wire mesh containers are rugged, durable, tough, and strong and capable of storing a wide assortment of materials. They are often used for holding metal parts and other production materials. Most wire mesh containers are designed to fold flat for easy storage when not in use.
• Residential wire mesh fencing offers exceptional protection and is weather resistant. The installation of wire mesh fencing takes very little time and permits a view of the fenced in area. It can be used by itself or be a supplement to other forms of fencing.
• To complete a building project in stages, temporary retaining walls may be needed. Due to its affordability, wire mesh is sometimes used by contractors to create welded wire walls that serve as temporary retaining walls. For instance, they are simple to install and dismantle once the temporary retaining wall is no longer required, and they don't require expensive labor or equipment.
• Wire mesh is frequently used to secure the perimeter of construction sites. Wire meshes can be used as a barricade to enclose the area, keeping people out of the building site and ensuring worker safety. Additionally, wire meshes protect the workers' safety and enable them to stay safe and free from dangers, injuries, and construction-related mishaps. Its strength and adaptability make steel ideal for use in fencing.
• Additionally, wire mesh sheets can be utilized as roadblocks for various construction-related heavy machinery. By doing this, one can also protect their pricey equipment from theft and damage. Additionally, wire mesh sheets can divide spaces for construction equipment and vehicles.
• Wire mesh for roads and superhighways has various benefits. High-yield steel used to make welded wire mesh can be even stronger than rebar. Workers employ wire mesh to reduce traffic congestion and prevent lengthy lane closures. Wire mesh can also reinforce roads; for instance, a wire mesh can be woven into a collection of hexagonal meshes. Layers of this sort of mesh are utilized for integrated pavements. It can help find solutions to problems like surface rutting and cracking. For fresh asphalt surfaces, hexagonal wire meshes can also minimize or lessen fracture reflection and asphalt fatigue.
• Concrete highways, columns, slabs, and other structures can all benefit from the added strength of wire mesh. Concrete constructions are prone to cracking, but wire mesh helps keep the material together. They serve as a sturdy core and improve structural integrity. Reinforced steel bars are typically employed to pour concrete. However, welded wire mesh offers contractors an alternative because it is strong, quick to install, and considerably more economical than reinforced steel bars. It aids in preventing concrete fractures from developing.
• Wire mesh is additionally used to support concrete beams while constructing temporary bridges and pathways for muddy and holey locations. In addition, it can be utilized to strengthen concrete structures while constructing runways at airports, house floors, and walls, to name a few.
• Wire mesh is not only useful in construction but may also be utilized to make temporary storage for employees' building supplies. Construction materials can be divided using the wire mesh. Employees at a construction site create wire mesh storage racks for their personal protection equipment, such as gloves, hard helmets, safety vests, goggles, and shoes. Since they can see their equipment and supplies in wire mesh storage racks, it also makes organization convenient.

Conclusion

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.

Leading Manufacturers and Suppliers

If you&#;re into construction, carpentry, and transportation, to mention but a few, you&#;ve most likely used a metal mesh.

A metal mesh is an expanded sheet or roll of metal consisting of strands of metal running from one end of the sheet to the other. These strands form openings of different sizes that form a barrier hence the name mesh.

The size of the openings ranges from the smallest size 1/8&#; x1/8&#; to the biggest size 6&#; x6&#; while the size of the entire expanded sheet can be as big as 10 feet long for a standard sheet and 100 feet long for a standard roll. The openings can also take different shapes such as a square, hexagon, diamond, and circle.  

Depending on the use of the mesh, you can choose one made of stainless steel, copper, aluminum, bronze, galvanized steel, brass, Monel, carbon steel, or brass. You can also make it from an alloy of the metals mentioned above. Therefore, the type you use depends on the material used or alloy, the size of the entire sheet or roll, and the shape and size of the openings.

This article will explore more on metal mesh, also known as expanded metal. You&#;ll learn how it is formed, its application, and the advantages of using it.

How Is A Metal Mesh Made? 

You&#;re probably picturing a welded or woven wire mesh by the description given above. However, note that these are two different types of products. The best way to tell the difference is first understanding how a metal mesh or expanded metal is made.

As mentioned before, a metal mesh is made from a sheet or roll of metal. The sheet of metal is put into an expanding machine where it&#;s made thinner so that it can stretch. As the sheet of metal stretches, its surface area begins to cut so that uniform holes are made on the metal.

The difference between a metal mesh and a wire mesh is that the metal mesh holes are molded within the metal sheet. On the other hand, the holes are made from thin strands of metal woven or welded together for a wire mesh.

Secondly, the metal mesh remains strong regardless of the expansion. Meanwhile, the thinner the wire mesh, the weaker it becomes. Therefore, a wire mesh is used for less intensive applications, and it&#;s relatively cheaper than an expanded metal.

Applications Of Expanded Metal 

The uses of a metal mesh can be summarized as protection as a barrier, support in the construction industry, and custom applications such as decorations. Here are the applications of a metal mesh:

• Construction industry. The mesh is used to support parts of the construction such as adobe in walls, plaster, or stucco. 
• Modern architecture. The expanded metal has found a niche in modern technology where the metal mesh is being used to form decorative features and building facades. 
• Filtering water. An example is in large gabions to avoid soil erosion. 
• Infill panels
• Used to make ventilations for big machines  
• Functional and decorative trellis

Here are the advantages of using expanded metal for all your needs:

1. Metal Mesh Is Made From One Material

As detailed in the article, expanded metal is made from one sheet of metal being stretched. Out of this fact only, there are two advantages of using it. First, there&#;s less waste while designing one, and second, the metal retains its strength. The two will be discussed further in the points to follow.

Other than these benefits, it can easily undergo further transformation such as sheering and pressing since they&#;re made of one piece of metal sheet. As such, should you need to change the form of the mesh, you won&#;t have to purchase a new one. 

2. Minimum Waste Is Produced

Creating the holes on a metal mesh involves stretching the sheet of metal as opposed to punching holes into it. If you punch holes, the punched-out metal can&#;t be used, which increases the amount of waste produced.

3. A Lower Cost

If you&#;re producing little to no waste, it means you&#;ll need fewer sheets of metal, which will cost less than if you&#;re throwing some away as waste. Additionally, some metals can expand more to cover a large area. If this is the case, you may end up needing fewer sheets or rolls of metal for your design.

4. A Metal Mesh Is Strong

When the sheet of metal is expanded, it loses some of its weight. However, this doesn&#;t compromise the integrity of the metal. Therefore, the uncut parts of the metal remain sturdy and the stretched strands can withstand more pressure as compared to woven or welded joints. The strength makes it suitable to offer support to other structures during construction.

5. Metal Mesh Has Anti-Slip Properties

As mentioned, the strands of the metal forming the openings are stretched from the metal sheet. The knuckles where the strands meet have a firm grip as opposed to if these strands were woven. The sturdiness of the knuckles makes them anti-slip, which is most appropriate for constructing walkways, stair treads, and ramps.

6. It&#;s Highly Efficient

Because a metal mesh is made of one piece of material and there are no breaks from one strand to another, electric and magnetic energy flow continuously throughout the mesh. As such, if you intend to use it for any power-related tasks, you can be sure of efficiency and reduced loss of energy since a metal mesh has minimal destruction.

7. It Can Be Made From An Alloy

When processing you can mix two or more metals to strengthen the mesh, increase its expansion capability, and sometimes for aesthetic purposes. Whatever your reason, a metal mesh allows you to play with different metals to achieve your desired alloy.  

8. Flexibility 

It gives you the flexibility you need to mold a mesh of your own design and aesthetic while still maintaining optimum functionality. For example, if you want to achieve more light you can use larger cuts to create large openings. With a perforated mesh, however, the larger the cuts, the weaker the mesh, which means that eventually, the it won&#;t serve its purpose.

To Sum It Up

Although their physical appearance is alike, there&#;s a difference between a metal and a wire mesh. The metal mesh is stronger, more expensive, and has more benefits. It&#;s made of one material, so there&#;s minimal waste produced; and due to reduced waste, it&#;s cheaper to mold and use a metal mesh.

Other advantages are that it is strong with sturdy knuckles that make it suitable for anti-slip constructions such as walkways. Moreover, it is highly efficient, it can be made from an alloy, and finally, it&#;s flexible to different designs and functions.
