Stainless steel wire mesh is a versatile material used in filtration, screening, and security applications across industries. A key technical specification to understand is mesh count — it directly impacts the performance and suitability of the mesh for your project.
Mesh count refers to the number of openings (or “meshes”) per linear inch (or centimeter) of the wire mesh. For example, a 100-mesh screen has 100 openings per inch in both the horizontal and vertical directions.
– Higher mesh count → smaller openings, finer filtration, and better particle retention.
– Lower mesh count → larger openings, higher flow rates, and greater structural rigidity.
It is important to note that mesh count is distinct from wire diameter. Two meshes with the same count can have different performance characteristics if they use different wire thicknesses.
Quick Selection Guide
Application Scenario Recommended Mesh Count
Fine powder filtration 150–325 mesh
Water purification 50–150 mesh
Grain/seed screening 10–40 mesh
Security fencing 4–20 mesh
Ventilation/ insect screens 18–24 mesh
Final Tips
– Always verify the opening size (not just mesh count) to ensure it meets your exact requirements, as wire diameter can vary.
