A circular wire mesh screen is a round, flat component made by weaving or welding metal wires into a controlled opening pattern. It is used to separate particles, filter liquids or gases, protect openings, support filter media, or distribute material flow. I manufacture and supply circular wire mesh screens in materials such as stainless steel, galvanized steel, mild steel, and other metals according to the application and drawing requirements. The final screen is defined by its outside diameter, mesh or aperture, wire diameter, material, edge finish, and required quantity.

A circular wire mesh screen normally consists of a mesh area and, depending on the design, an outer edge or supporting frame. In woven mesh, wires pass over and under one another to form regular square, rectangular, or other specified openings. In welded mesh, wires are joined at their intersections, creating a more fixed and rigid structure.
The circular shape is usually produced by cutting mesh from a larger sheet or roll, although some designs may be formed or assembled as part of a filter element. The cut edge can be left plain, reinforced with a ring, folded, spot-welded, or combined with multiple layers. I recommend confirming the edge treatment because it affects handling safety, installation, sealing, and resistance to deformation.
The core function is controlled separation. A screen allows selected material, fluid, or air to pass through its openings while retaining particles or providing a physical barrier. The correct result depends on the opening size, material properties, flow conditions, pressure, temperature, and the way the screen is installed.
In filtration, the screen can remove particles from liquids, polymers, powders, fuels, oils, or process gases. In screening equipment, it can classify granular materials by size. In industrial protection, it can cover vents, nozzles, openings, and components while allowing ventilation or drainage.
Circular screens are suitable for equipment that has a round flow path, housing, opening, or cartridge interface. Their geometry can reduce the need for additional cutting during assembly and can make replacement more straightforward when the original component is also round. However, the screen must match the equipment’s seating surface and sealing method.
Common applications include plastic extrusion filter packs, hydraulic and pneumatic equipment, water treatment components, laboratory filtration, food and beverage processing, chemical processing, mining screens, agricultural machinery, air intake protection, and burner or nozzle assemblies. The application does not determine the screen specification by itself, so I still need the working conditions before recommending a final construction.
| Application | Primary Screen Requirement | Important Buyer Information |
|---|---|---|
| Plastic extrusion | Stable openings and resistance to process heat | Polymer type, operating temperature, layer structure, and pack diameter |
| Liquid filtration | Controlled aperture and suitable corrosion resistance | Fluid chemistry, pressure, flow rate, and retained particle size |
| Ventilation protection | Open area and mechanical stability | Airflow, environmental exposure, mounting method, and cleaning requirements |
| Powder screening | Consistent opening distribution and wear resistance | Particle shape, abrasiveness, throughput, and screen tension |
Stainless steel is a common choice when buyers need corrosion resistance, cleanability, or stable performance in demanding environments. Stainless steel 304 is widely considered for general industrial use, while 316 or 316L may be evaluated where improved resistance to certain corrosive conditions is required. Material selection should be based on the actual medium and operating environment rather than on the material name alone.
Galvanized steel can be considered for applications where a zinc coating provides basic corrosion protection and cost control. Mild steel may be suitable for dry, indoor, or less corrosive conditions, especially when the screen will receive an additional coating or protective treatment. I can also discuss other metal options when the operating temperature, electrical, chemical, or mechanical requirements make standard materials unsuitable.

A purchasing request should include more than the phrase “circular wire mesh screen.” At minimum, I need the diameter, material, mesh or aperture, wire diameter when known, thickness or layer count, quantity, and edge condition. A technical drawing or sample is especially useful when the screen must fit an existing assembly.
For reference, a buyer may specify an outside diameter of 100 mm, an aperture of 50 micrometers, or a wire diameter of 0.20 mm. These are specification examples rather than universal product limits, because the practical range depends on mesh construction, material, diameter, and manufacturing method. I confirm the manufacturability and tolerance after reviewing the complete requirement.
I recommend starting with the function rather than the material. If the screen is intended to retain particles, identify the target particle size and determine whether the process requires nominal separation or a tighter controlled opening. If it is used as a guard or support layer, open area, strength, and mounting may be more important than fine filtration.
Next, review compatibility with the working environment. Corrosive fluids, elevated temperature, repeated cleaning, vibration, pressure difference, and abrasive particles can all change the suitable material or structure. A screen with very small openings may provide finer separation, but it can also create higher flow resistance or clog more quickly, so performance must be balanced against maintenance requirements.
At Guangtong, I support B2B buyers by reviewing drawings, samples, mesh requirements, materials, edge designs, and packing instructions for circular wire mesh screens. My role is not only to provide a metal disc, but also to help translate the application into a manufacturable specification. When a requirement is incomplete, I identify the missing information instead of making an unsupported assumption.
For repeat orders, a clear approved specification can help keep the diameter, aperture, material, layer arrangement, and packaging consistent. For new projects, I can review whether a woven, welded, single-layer, or multi-layer construction is more appropriate based on the stated use. Final tolerances, production feasibility, and inspection details should be confirmed before purchase.
A circular wire mesh screen is a round mesh component used for filtration, separation, protection, support, or flow distribution. Its performance is determined by the relationship between aperture, wire diameter, open area, material, edge construction, and operating conditions. The best specification is therefore application-specific rather than selected by diameter alone.
For a reliable quotation, prepare the required diameter, mesh or aperture, material, thickness, edge style, quantity, and application details. If you have a drawing, sample, or photograph of the installation, send it for review. I can then help evaluate the suitable construction and prepare a practical B2B supply proposal from Guangtong.
If you are sourcing circular wire mesh screens for filtration, screening, equipment protection, or industrial assembly, contact Guangtong with your drawing or technical requirements. Please include the outside diameter, aperture or mesh count, material preference, quantity, and working conditions whenever available. I will review the information and respond with the next suitable step for sampling, quotation, or production planning.
