What is stainless steel pre-crimp mesh and Why Do We Use Them?

Heavy Duty Stainless Steel Wire Mesh is also called Crimped Woven Wire Mesh. Stainless steel crimped woven wire mesh is a kind of multipurpose mesh in different materials. The metal wire is crimped first and then woven by the crimped wire mesh machine. The crimp type can be divided into Intermediate Crimped, Flat top Crimped, Pre-crimped Woven, and Lock Crimped.

Stainless steel crimped woven wire mesh has two main types, first is plain-woven stainless steel crimped mesh, and the other one is intermediate crimp stainless steel crimped mesh. The plain woven means that there is no corrugation in a mesh hole, and the intermediate crimp means there are 1 or more corrugations in a hole. The plain woven is mainly used for the mesh with large wire diameter and small mesh size, and the intermediate crimp is usually used to produce the mesh with a large hole size and small wire diameter.

Compared to the material, woven craft, and usages, there are not too many differences between plain woven and intermediate crimp, and they can instead each other. If we want to tell the difference in detail, the plain woven mesh will be softer than intermediate crimp mesh and has better abrasion resistance. According to this, we can decide which type to be used for different applications.

According to the material, the crimped woven wire mesh can be divided into galvanized steel mesh, carbon steel mesh, iron steel mesh. It can also be divided into mining screen mesh, feeding screen mesh, granary mesh, and Decorative Wire Mesh. 

Heavy Duty Woven Wire Mesh has a width range from 1 to 8 meters. It has a very stable structure and is very also very tough, mainly used in the Mining, Architecture, Petrochemical Industry, Machinery. And the mesh types are various according to the material, wire diameter, and mesh opening size.

Weaving is everything when it comes to stainless and industrial wire cloth with woven wire mesh and wire mesh panels. The weave is what determines how the wire cloth can be used and in what capacity. With that in mind, here is a list of the types of weaves to choose from when purchasing wire cloth-related products.

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.
