Wire mesh is a common type of metal screen consisting of parallel rows and intersecting columns of wire. Although similar in appearance and their applications, perforated metal sheet and expanded metal sheet are not types of wire mesh. Wire mesh comes in an almost limitless amount of shapes and sizes, and a large variety of materials and metal alloys.

The intersecting wires are typically joined together by welding or weaving &#; two of the more common forms of wire mesh. The solid wire used is usually made by progressively drawing down a metal in a series of round dies until the desired diameter has been achieved.
There are two common types of mesh:
Welded wire mesh has intersecting rows and columns of parallel wires that are welded together at the intersection. Once the wire has been drawn down to the desired size, it is fed into a machine which welds the multiple rows of wire together at their intersection.
As the mesh is fed through the machine, a parallel line of welds is created simultaneously where the perpendicular lines meet. The next intersection of wires is then fed through the machine to be welded, and this process continues, joining each row of wires together. This machine typically welds the wires using electrical resistance as the source of heat. Although other welding methods could be employed, this is the usually most economical. Once the mesh has reached the desired length, it is cut by a shear, resulting in a sheet of flat and rigid welded wire mesh.
Woven wire mesh has an array of intersecting wires, similar to a woven cloth. Typically, the wires are woven over and under the perpendicular wires producing a stable sheet. This pattern is known as a &#;Plain Weave Mesh&#;. For applications that require a more flexible sheet, a &#;Twill Weave&#; can be used.
This involves wire that is woven over 2 perpendicular wires, then under the next set of 2 perpendicular wires, and so on. Woven wire mesh has no welds on them. Instead, they are fed into a machine similar to a loom which feeds a straight wire through chosen weave pattern. The wires are then bent to the reverse position, and the next straight wire is fed through the pattern. The machine continues this process until the desired dimensions are reached and the completed wire mesh sheet is then cut to the desired size.
Welded wire mesh and woven wire mesh are used in many different fields. Several uses include:
Wire mesh and wire cloth are highly versatile products made from a network of interlaced wires.
Wire cloth is generally flexible with a smooth cloth-like consistency. Most specifications use thinner wire diameters that create very small to small micronic openings. As a result, this material is a perfect medium for screening and filtration applications.
Wire mesh on the other hand incorporates larger openings and thicker wire diameters. These materials are ideal for cages, fencing, and ventilation covers.
By changing the opening size and wire diameter a variety of specifications are available to accommodate many applications, whether it&#;s a mesh panel for architectural installations or a heavy-duty wire mesh product for industrial purposes.
Woven wire mesh is a (often steel) metal mesh made using special weaving equipment, intricately weaving metal wires together to form a cohesive structure.
Typically, wire cloth utilizes a plain weave construction meaning the wires just pass over one another at each intersection.
For mesh with larger openings and thicker diameters, there is an entire crimping process prior to configuring the weaving loom. This process pulls coiled wire from a rack into the crimping machine. The wire is first straightened and then crimped to a specific profile using a set of toothed wheels. The wire is then accurately cut to the desired length and width ready to be woven.
Depending on your requirements, these special weaving looms can construct various woven wire mesh specifications, incorporating metal wires of different materials and diameters.
Stainless steel wire mesh has many attributes, making it highly desirable for a number of applications.
Besides stainless steel, other materials are available to create woven wire mesh, including:

Individuals looking to get woven wire mesh must know the three fundamentals to get the right product for their needs, including wire mesh product specifications and metal varieties.
You may hear terminologies such as 4 or 100 mesh count when shopping for wire cloth, which refers to the number of openings in an inch.
Knowing the mesh count will help you get a solution that allows you to have control over what passes through the mesh. For example, if you&#;re working at an oil rig, you would need a mesh with 100 openings or more, depending on what you want to filter out.
Typically, for finer filtration, oil rigs use meshes with many small opening sizes to filter out sand and other impurities when pumping out oil from the ground.
For heavy-duty wire mesh, this might be a measurement in fractions of an inch to determine the opening or mesh centers. This is ideal for aggregate sizing and sifting applications.
Wire diameter is the thickness of each wire which determines the following:
If the wires are thicker, there will be a smaller open space, making the weave durable and more resistant to harsher conditions. However, thinner wires may allow for more open space but could result in more wear and tear depending on the application.
There are different specifications of wire meshes depending on the wire diameters. For example, working with coarse aggregates, you would likely want a thick wire diameter better suited to withstand material processing. However, a slightly thinner wire diameter would be ideal for as machine guard to protect the operator and equipment while allowing for ventilation.
The opening size is the distance between the wires.
Knowing the mesh count and opening size can help determine your required micron rating. For filtration, micron rating is crucial as it gives the user more control over the medium.
The following are some common types of woven wire mesh:
Each type has its unique properties. For example, the lock crimp offers greater stability, while the flat top crimp features a smooth top allowing for a better flow of materials. Besides the types mentioned above, you can also find various architectural patterns for your creative installations.
There are many woven wire cloth types you can choose from, including:

This article has shed light on the fundamentals of woven wire mesh, detailing its manufacturing process, materials used, and key considerations in selecting the appropriate mesh for specific applications, including stainless steel and aluminum wire mesh.
The distinction between wire cloth and wire mesh, underscores the tailored functionalities each offers, whether for screening and filtration purposes or structural applications like fencing and ventilation. Moreover, understanding mesh count, wire diameters, and opening sizes empowers users to make informed decisions aligning with their requirements, whether for fine filtration in oil rigs or robust protection in industrial settings.
Furthermore, the exploration of different types of woven wire mesh, from plain crimp to lock crimp, reveals the rich diversity of options available, each with its unique properties suited to various demands. Likewise, the array of woven wire cloth types, such as plain square woven and Dutch twill weave, showcases the breadth of creative possibilities and functional adaptations achievable with this versatile material.
In essence, woven wire mesh epitomizes versatility and ingenuity, offering a blend of functionality, durability, and aesthetic appeal across industries ranging from industrial to architectural.
