When designing the ideal internal wire screen, selecting the weave pattern is critical to achieving the desired performance, efficiency, and durability. Knowing which weave pattern is right for you starts with understanding the differences between square and slotted weaves.
Each woven wire variant has advantages that improve the efficiency and longevity of your operation. That leaves us wondering, "How do square and slotted weave industrial wire screens differ?"
W.S. Tyler strives to deliver innovative wire mesh solutions that make the world cleaner and safer. We do so by leveraging our 150 years of wire mesh experience to help guide wire mesh users like yourself toward solutions that help achieve your operational goals.
With that, this article was written to highlight the critical difference between square and slotted mesh and illustrate which is best for you. It will cover:
Square mesh is a woven wire mesh weave in which the width and height apertures are identical, forming square pore openings. These openings are precise and uniform, so consistent particle separation is easily achieved.
This makes square weaves work particularly well for applications in which size control is critical.
Versatile in nature, square mesh vibrating screens are employed in various industries, including mining, agriculture, pharmaceuticals, and food processing. Various alloys can be used to weave your mesh to ensure your screens provide long-lasting screening.
A stainless steel variant, typically 316 stainless steel, is often used.
The overall quality and accuracy of square mesh works to deliver high-performing cut points.As a result square mesh weaves are known to provide excellent screening results.
This is particularly evident when working with finer particles.
When you look at the weaves of square mesh, the open area remains consistent throughout the weave. This uniformity ensures a consistent flow rate and, again, efficient screening.
Additionally, the square opening uniformity evenly distributes stress when tensioned.
Because of the precise square openings, square weaves can have a relatively tight percentage of open area. This means that they tend to be limited in capacity.
And as the capacity level decreases, the time needed to thoroughly screen material increases.
Additionally, the tight parameters of the square openings can sometimes enhance the risks of pegging and blinding.
Pegging: The occurrence in which near-sized particles get stuck in between the wires
Blinding: The occurrence in which wet material accumulates on the surface of the wires,
blocking off the openings.
Slotted mesh refers to woven wire mesh weaves outfitted with elongated openings. These rectangular openings are designed to improve the ability to separate elongated particles or particles that are irregular in shape.
This works to combat pegging and blinding.
At the same time, the increased percentage of open area means that screening capacity and material flow rate increase. This makes slotted weaves ideal for high-volume mining, food processing, recycling, and agriculture applications.
Much like square mesh weaves, slotted weaves are often constructed from stainless steel alloys, ensuring optimal longevity.
With fewer wires in the warp direction, slotted mesh weaves are more open than square weaves. This results in a reduced risk of pegging and blinding.
You will also find that slotted opening mesh increases throughput at the same wire diameter. This means that screen capacity dramatically increases, reducing the time spent screening.
The open properties of slotted weaves allow heavier wires to be used during the weaving process. Heavier wires can better combat wear and tear, meaning your screen sections last longer.
As slotted mesh screen sections utilize minimal wires in the warp direction, they cannot be woven to finer specifications. This means that these weaves typically lack the accuracy to screen finer materials like sand.
Because of this, slotted opening mesh is limited in terms of versatility.
Additionally, because of the rectangle profile of the pore openings, slotted screens can create a directional bias. This can sometimes affect the flow of material, thus causing dissimilar wear that alters structural integrity and reduces lifespan.
When determining whether to construct your industrial wire screen using a square or slotted mesh, three factors must be considered: screen durability, accuracy, and capacity.
That said, the specific needs of your operation and the properties of the material being screened determine the weave you should be using.
Square openings are preferred for applications that demand accurate screening of particles smaller than 3mm. They offer a better cut-point while maintaining desirable durability and structural integrity.
Square weave must also be used when the screened particles are elongated in shape, as slotted weaves won't retain them well.
Slotted openings, on the other hand, are favored in processes that rely on maximum flow capacity. These weaves offer up to 25% more open area, allowing peak throughput.
Their open profile also allows thicker wires to be used, combating day-to-day wear and expanding the screen's lifespan.
However, to create a screen that is truly tailored to your needs, you must remain mindful of the particle retention threshold, material properties, and your operation's environment.
Understanding the differences between square and slotted weaves can significantly impact the efficiency and longevity of your industrial wire screens. Choosing a weave that best accommodates your process will help facilitate optimal screening with minimal downtime.
However, as you start to piece together the perfect industrial wire screen, you must consider how the different elements of these screens affect their cost. If you discover that a particular speciation does not fit your budget, you can begin to value engineer the screen until you find the perfect cost/performance balance.

Building the foundation of a high-performing, highly efficient vibrating screen machine starts with selecting an appropriate weave to fabricate your industrial wire screen sections. Slotted mesh weaves, for example, are designed to accommodate high-volume operations that struggle with screen blinding.
Slotted mesh screen sections' versatile characteristics can optimize the classification performance of countless operations, from improving material throughput to enchanted durability. However, you must pick the right one.
At W.S. Tyler, we strive to leverage our 150 years of woven wire to manufacture slotted mesh screen sections that promote peak productivity across dozens of industries. Driven by precision and innovation, our mission is to help create a cleaner, safer world.
With that, we wrote the following article to highlight the various slotted mesh weaves we offer so you can better understand how slotted mesh can help you achieve your screening goals. It will explore:
The weave pattern you select is imperative for industrial wire screen sections. It ultimately determines how well your screen section separates and classifies material.
But it also impacts the overall efficiency of your screens. This is due to the fact that weave patterns have their percentage of open area, controlling flow rate, clogging resistance, and other factors that influence the passing of material.
Not to mention that, as certain weave patterns require more labor than others to produce, it will control the price of your screens. Simply selecting the right weave is critical to achieving peak performance and longevity.
Slotted wire mesh is a classification of weave patterns outfitted with elongated rectangle openings. These openings increase the percentage of open area, improving material flow while combating blinding/pegging.
The unique characteristics of these weaves have proven to benefit applications that rely on screens with improved strength and durability. The open properties of the weave allow thicker wire diameters to be used.
This is in addition to virtually every aspect of the weave, including wire diameter, mesh count, aperture size, alloy, etc.
This makes slotted wire mesh weaves ideal for high-impact, high-volume applications that subject the screen to abrasive materials.
Want to learn how reliable weaves are woven? Read the article below:
The openings of a standard slotted mesh weave have a length-to-width ratio of 1:3. So, for example, a .5mm opening would have a 1.5mm slot.
Typically, wire diameters of the equivalent square opening are used to weave slotted mesh. However, this can be customized to accommodate the following:
That said, slotted mesh comes in four weaves: TON-CAP, EGLA-MAX, plain weave, and TY-ROD. It should be noted that each weave is available from opening 0.1x0.3 mm and bigger.
TON-CAP, referring to tonnage capacity, is a slotted weave known for accommodating high-capacity operations. Exclusively available through W.S. Tyler, this weave features an opening ratio of 1:6 to 1:15.
Heavy wire diameters are used because they are designed to handle high volumes of material screening and classification, providing a longer service life.
The EGLA-MAX weave utilizes straight wires to achieve aperture proportions of up to 1:25. This ratio allows for the use of heavier wire diameters while maintaining a desirable percentage of open area throughout the weave.
This particular weave features two weft wires for every group of cross wires. This promotes tight connections between the warp and weft wires and enhanced weave stability.
With a large percentage of open area, desirable throughput and capacity are achieved.
Slotted Plain weaves are outfitted with elongated parallel openings that are uniform in size. This makes the weave perfect for accurate and repeatable material separation.
The slotted profile of the openings allows optimal throughput while combating pegging/blinding. You are left with a screen section that offers long-lasting performance.
It is widely used for its perfect balance of durability, screening efficiency, and ease of maintenance.
TY-ROD and EGLA-MAX share several profile similarities. TY-ROD offers more open area than plain slotted weaves and TON-CAP.
TY-ROD specifications feature slotted openings that reach two inches in length.
The resulting effect is a wire mesh screen section with peak flexibility and throughput. The larger elongation of the slotted openings combats blinding in particular.
This can prove beneficial for applications that screen finer aggregates that often adhere to the surface of the mesh.
You should be aware of several pitfalls when constructing your industrial wire screen sections out of slotted mesh. First and foremost, depending on the positioning of the elongated slots in your equipment, the openings present the risk of directional wear.
Significant directional wear is often the root of uneven degradation and screens with short lifespans. The openings can also cause uneven wear patterns, causing isolated fault areas.
The elongated profile of the openings makes it easier for elongated particles to pass the screen. This ultimately means your end product should be more uniform and could be.
Selecting the right slotted mesh weave is imperative when fabricating an optimal industrial wire screen section. For this reason, you must learn all the advantages each weave offers to enhance your operational success.
But to ensure your next screen sections take your operation to greater heights, you must gain insight into the cost of your desired screen section specifications. Understanding these key factors will allow you to make informed decisions, ensuring the perfect balance of cost and performance.
