What Are Woven Wire Mesh Filters?
A woven wire mesh filter consists of metal wires intricately woven together to create a uniform and strong filtration medium. The mesh structure can vary based on wire diameter, weave type, and opening size, allowing customization for specific filtration needs. These filters are commonly manufactured using materials like stainless steel, brass, copper, aluminum, and galvanized steel, ensuring excellent resistance to corrosion and mechanical stress.
Types of Woven Wire Mesh Filters
1. Plain Weave Mesh
The simplest form of woven wire mesh, where each wire alternates over and under adjacent wires, creating a uniform and stable structure. It is widely used for basic filtration needs.
2. Twill Weave Mesh
A more intricate weave where each wire crosses over two and under two adjacent wires. This provides higher strength and finer filtration compared to plain weave mesh.

For businesses looking to invest in high-quality woven wire mesh filters, partnering with a reputable supplier ensures customization, durability, and superior performance.
Woven wire mesh is arguably one of the most versatile materials in the world, as it can be formed to accommodate almost any filtration or design application. With other materials, such as wedge wire, on the market, woven wire mesh stands out as it balances performance with cost-savings.
But as no one operation is the same, buying customized wire mesh screens and filters proves to be ideal in most cases. With that, it is important that you know what to expect when building a customized wire mesh part so optimal results are achieved.

Building the Perfect Mesh Specification
There are several specifications that must be methodically determined while designing the ideal custom mesh screen/filter. Of these specifications layer configuration, size and shape, and mesh count can be the hardest to determine.
Single- vs. Multi-Layer
There are several reasons why a multilayer configuration would be best for your operation. Of these reasons, the biggest deciding factor would be the need for strength and durability.
Let’s say you are filtering a substance or screening a material that has various particle sizes. If you were to simply use a single layer of fine mesh, odds are it wouldn't hold up as the larger particles would compromise the integrity of the mesh in a short period of time.
To combat this, you would take the fine mesh needed to deliver the filtering capabilities and sandwich it between layers of stronger, more coarse mesh. Doing so will prevent the larger particles from damaging the finer filter layer.
That said, if you are filtering non-abrasive material or seeking to obtain the filter cake, a single-layer configuration will best suit your needs.
Size and Shape
When working with woven wire mesh, in particular, the sky's the limit when it comes to the ways it can be formed to accommodate your operation. That said, there are a few aspects to the forming process that simply can’t be done.
When forming deep drawn funnel screens for low-pressure die casting, for example, there is a ratio, based on the screen’s diameter, that limits the depth in which the screen can be drawn. This ratio essentially limits the depth measurement from exceeding the measurement of the diameter of the screen.
Putting this into perspective, if you require a screen that is one inch in diameter, it would be impossible to draw the part out to a measurement of 5 inches.
Mesh Opening Size
The mesh opening size that best suits your operation ultimately depends on the particles you are working with.
If you are screening large pieces of aggregate you will want to use larger mesh openings as they will allow the large particles to pass while also accommodating the wire diameter needed to create a durable screen. On the other hand, if you are filtering out sand from raw oil, a finer mesh count will be needed as these particles can prove to be small.
With that, the mesh count of the screen may be limited based on the type of woven wire cloth. Square mesh has a mesh count range of 4 mesh down to 230 mesh whereas filter cloth has a mesh count range of 4 microns to 302 microns.

Important Information for Wire Mesh Inquiries
When trying to identify the wire mesh needs of a customer, there is a “Good, Better, Best” scale that is used. With that, there are three primary mesh elements that dictate how effective the mesh supplier is at helping you establish the perfect mesh solution:
What Does the Buying Process Look Like?
Regardless of the needs of your wire mesh part, the buying process starts with reaching out to the mesh supplier with an overview of the mesh to see if it can be produced. Typically, you will be asked to submit some sort of drawing or blueprint with the mesh specifications so an engineer can review them.
Read the article below for an in-depth breakdown of what you should expect when submitting a wire mesh drawing:

If neither a blueprint or drawing is available, our team of experts can work with you to determine which specifications will work best for your needs.
Once the engineer confirms that the desired mesh specification can be produced, you will receive a quote reflecting the cost of the materials needed to produce the mesh. With that, it is important that you know the different elements of the desired mesh specification.
This includes:
- The mesh count
- The alloy of the mesh
- Any sort of heat treatment needed
- Any value-added services needed
Once you receive the quote, the final step would be to accept it and submit a purchase order. Taking all this into consideration, the biggest obstacle you will face during the buying process is if the mesh can be produced.
