Crimped Wire Mesh

Pre-Crimp Weaves
First, let's take a look at the pre-crimp weaves. These weaves are typically used for wire and space cloth that is more on the coarse side. The following is an overview of the three different types:
Pre-Crimp – Generally speaking, to add strength and rigidity to the wire cloth, pre-crimp weaves are crimped (or folded so the wires have small folds or ridges) before they are weaved. This makes it possible for the warp and shute wires to rest securely and prevent them from unnecessary movement.
Lock Crimp – Another type of pre-crimp weave is the lock crimp. This type of weave uses the grooves left from the crimping process to literally lock the weaves together at the point in which they intersect. This makes the wires sturdier and further prevents movement.
Inter-Crimp or Multiple Crimp – Lastly, the inter-crimp or multiple crimps offers yet another enhancement on the basic crimp weave. With this method, both the warp and shute wires are crimped with added crimps between the points of intersection. This technique is often needed when weaving larger openings with fine wires. The process ensures that the warp and shute are properly locked and also helps to add accuracy and rigidity.

Plain Weaves
This is the most common type of weave used for wire cloths. In this case, there is no pre-crimping before the wires are weaved. Rather, the crimping of both the warp and shute is a result of the plain weave pattern requires that each shute wire must pass over and under successive rows of warp wires.

Filter Cloth
In terms of filter cloth, the types of weaves to be aware of are as follows:
Plain Dutch Weave – This type of weave uses a similar technique as that of plain weaves. However, the warp wires have a larger diameter than the shute wires. The lighter shute brought closer together, which forms a dense filter. This weave appears to be wedge-shaped or tapered at the opening.
Twill Dutch – This filter cloth includes a combination of twill and Dutch weave. This uses a technique in which the warp wires that are larger in diameter pass over and under the smaller shute wires. This caused the shute to be closer and results in a filter cloth that is tightly woven and with wedge-shaped or tapered openings.
Twill Dutch Double – This is similar to the Dutch twill weave. However, due to wires sizes that are properly chosen, the shute wires overlap before they are driven into their tight positions. This makes for double wires in the shute direction per inch.
Stranded – With this weave, both the shute and warp wires are made of separate wires, rather than single wires. This creates a twill pattern, which results in the mesh that is extremely strong and tight.

Twill Weave
Twill weave creates a wire cloth in which each shute and warp wire passes over and under the two adjacent wires successively; this occurs in both the shute and warp directions. This pattern makes it possible to weave heavier wires into various types of mesh.

While they may look similar, crimped wire mesh and woven wire mesh have several manufacturing and structural differences that you should be mindful of.

Looking at how it's made, crimped wire mesh requires a pre-crimping process that physically bends and alters the profile of the individual wires. This pre-crimping creates a more stable and rigid weave in which the wires are held in place better.

These crimps create a textured surface. But at the same time, helps maintain the shape of the mesh as well as the spacing of the openings.

That said, the crimped wire mesh renders the material more suitable for heavy-duty applications that subject the mesh to high levels of mechanical stress.

Woven wire, on the other hand, interlaces the wires of the weave at right angles and does not require the wires to be processed before the weaving process. The lack of crimping often results in a smoother surface.

While not as rigid, woven wire mesh is considerably more flexible and easier to form. This flexibility is, of course, heavily influenced by the wire diameter and weave pattern.

Choosing between the two mesh variants should be determined by the specific needs of your application.

Applications that require stronger, more robust weaves should rely on crimped wire mesh. Applications that require fine precision and increased flexibility must use woven wire mesh.

With its superior rigidity, crimped wire mesh is more likely to be used for screening in the mining, construction, and other heavy-duty industries. But as it is more flexible and often delivers finer specifications, woven wire mesh is typically seen in filtration and sieving applications.

Get To Know What Wire Mesh Is Right for You
Crimped wire mesh and women's wire mesh are both wire mesh variants designed to accommodate specific screening/filtration applications. Crimped wire mesh is best suited for heavy-duty industrial applications, whereas woven wire is widely used to deliver accurate separation of finer particles.

But it is important that you understand all the wire mesh variants available to you, including welded wire mesh. This knowledge will allow you to construct and implement the perfect solution and generate the results you need to succeed.
