Woven Wire Mesh: Precision Industrial Separation
Woven Wire Mesh is a precision screening medium utilised extensively across industrial sectors for separation, sizing, and filtration. By interlacing longitudinal and transverse wires, manufacturers create a stable and consistent aperture. This structural consistency ensures reliable particle separation in demanding processing environments.
For plant engineers and procurement managers, selecting the correct mesh is critical to maintaining product purity and protecting downstream machinery. Whether the application involves sieving food products, filtering petrochemical gases, or sizing aggregates in a quarry, the correct wire specification guarantees operational efficiency.
Tegman supplies a comprehensive range of Woven Wire Mesh to meet these industrial requirements. The inventory includes options ranging from fine mesh for precision filtration to medium weave mesh for bulk separation. Materials such as stainless steel and galvanised steel are available directly from stock, offered in standard 30-metre rolls or specifically cut to size.
What is Woven Wire Mesh?
Woven Wire Mesh is a durable and highly accurate screening material created by interlacing longitudinal wires (the warp) and transverse wires (the weft) on an industrial loom. This mechanical weaving process forms a stable grid with precise and uniform apertures.
Unlike perforated plates, which are punched from solid metal sheets, or welded mesh, where wires are permanently fused at intersections, woven mesh relies on the tension of the interwoven wires to maintain its structural integrity. This specific manufacturing method allows for the production of extremely fine and consistent openings, making it the preferred material for precision filtration tasks across various industries.
The interlaced structure ensures reliable particle retention. When liquids, gases, or bulk solids pass over or through the material, the exact dimensions of the weave allow specific elements to flow while effectively blocking oversized material.
Tegman supplies this essential product in two primary categories. Fine Mesh is available for tight filtration tolerances ranging from 1 to 2000 microns, while Medium Weave Mesh is provided for broader separation tasks ranging from 2000 to 25000 microns. The material is supplied in standard 30-metre rolls or can be precision cut to specific dimensions based on project requirements
Micron Ranges: Fine Mesh vs. Medium Weave Mesh
Selecting the correct aperture is the most critical factor in achieving efficient separation. The measurement of these precise openings is typically calculated in microns. Tegman categorises its ex-stock inventory into two primary ranges to serve distinct industrial requirements.
Fine Mesh
Fine Mesh is engineered for highly accurate Industrial Filtration. Tegman supplies this material with aperture sizes ranging from 1 to 2000 microns. Because the openings are microscopic, this mesh is essential for processes requiring strict particle retention. In the pharmaceutical industry, it is used extensively for liquid filtration and fluid bed dryers. It is equally critical in the oil and gas sector for the separation of liquids and gases, and in chemical processing for catalyst support
Medium Weave Mesh
For bulk material handling and sizing, Tegman provides Medium Weave Mesh. This category covers larger apertures ranging from 2000 to 25000 microns. The thicker wire and wider openings provide the necessary strength for heavy-duty sorting tasks. This specification is the standard choice for mines and quarries requiring reliable screening and sizing of aggregates and minerals. It is also widely utilised in the agricultural sector for grain sieves and in the food and beverage industry for bulk sieving and conveyor belts
Both ranges are available directly from stock to ensure minimal downtime for your processing facility
Material Specifications for Demanding Environments
Selecting the correct aperture is the most critical factor in achieving efficient separation. The measurement of these precise openings is typically calculated in microns. Tegman categorises its ex-stock inventory into two primary ranges to serve distinct industrial requirements.
Galvanised Steel (Electro Galv)
Galvanised steel provides a cost-effective solution for standard industrial and agricultural applications. The electro-galvanising process coats the wire with zinc to offer basic corrosion resistance. Tegman supplies this material primarily in Medium Weave Mesh configurations for use in fencing, grain sieves, and general screening tasks.
Stainless Steel 304 (SS304)
SS304 is the industry standard for general corrosion resistance and is widely used across the food and beverage, automotive, and chemical processing sectors. It provides excellent durability and hygiene properties. Tegman stocks a vast range of both Fine Mesh and Medium Weave Mesh in SS304 to ensure immediate availability for standard filtration and separation requirements.
Stainless Steel 316 (SS316)
For harsh environments requiring superior resistance to corrosive chemicals or marine conditions, SS316 is essential. The addition of molybdenum to the alloy significantly increases its resistance to pitting and corrosion. This grade is typically specified for demanding applications in the oil and gas sector, water treatment plants, and the pharmaceutical industry. Tegman supplies specific Fine Mesh configurations in SS316 for precision filtration where material degradation is unacceptable.
High Carbon and Mild Steel
In addition to the primary grades, Tegman also supplies specific mesh configurations in High Carbon (HC) and Mild Steel (MS) for specialised industrial applications requiring high tensile strength or where corrosion is not the primary concern
Understanding Weave Types and Patterns
The specific method used to intersect the wires determines the filtration capabilities and structural strength of the mesh. Tegman supplies several distinct weave patterns to suit varied processing demands
Plain Weave
The Plain Weave is the most common and straightforward pattern. Each transverse wire passes alternately over and under each longitudinal wire. This creates a standard square aperture and offers excellent flow rates for general filtration, separation, and sizing tasks.
Twill Weave
In a Twill Weave, each transverse wire passes over two and under two longitudinal wires. This specific technique allows manufacturers to use heavier wires for a given mesh count. The result is a stronger screen capable of supporting greater loads and withstanding higher pressures while maintaining fine filtration capabilities.
Dutch Plain Weave
The Dutch Plain Weave is designed specifically for precision, high-pressure filtration. In this configuration, the longitudinal wires are thicker and spaced further apart, while the transverse wires are thinner and driven closely together. This creates a dense, strong mesh with microscopic, wedge-shaped openings that provide exceptional particle retention.
Dutch Twill Weave
This pattern combines the twill and Dutch weaving techniques to achieve the finest possible filtration. The overlapping wires create a highly robust, tortuous path for fluids. It is the standard medium for filtering heavy liquids, fine powders, and gases where absolute micron ratings are required.
Reverse Dutch Weave
As the name suggests, this pattern reverses the standard Dutch weave arrangement. The longitudinal wires are thin and closely woven, while the transverse wires are thick. This creates a highly durable mesh with excellent tensile strength, frequently used in high-pressure vertical filter systems and continuous automatic screen changers.
Custom Fabrications and Industry Applications
