3mm Wire Mesh

Mesh size in millimeters refers to the opening dimension between adjacent wires. For knitted wire mesh products, typical openings range from 4mm to 5mm, though finer or coarser configurations are available depending on the filtration efficiency, porosity, or shielding performance required for a specific application.

18 gauge wire measures approximately 1.02mm (0.0403 inches) in diameter under the standard American Wire Gauge (AWG) system. While most knitted wire mesh products use finer wires (0.10mm-0.30mm) for flexibility and high surface area, heavier gauge wires like 18 gauge are used in more rigid woven mesh applications requiring structural strength.

19 gauge wire measures approximately 0.91mm (0.0359 inches) in diameter per AWG standards. This gauge is slightly thinner than 18 gauge and is commonly used in industrial woven or welded wire mesh where a balance of durability and flexibility is needed, though knitted mesh typically uses much finer wire diameters.

Knitted wire mesh is produced from stainless steel (SS304, SS316, SS316L), copper, brass, aluminum, galvanized iron, and specialty polymers. Material selection depends on the application: stainless steel offers corrosion resistance and strength, copper provides high electrical conductivity for EMI shielding, and polymers suit aggressive chemical environments where metals fail.

Minimum order quantities typically start at 100 kg for knitted wire mesh and multiwire mesh products, though this can vary by material, roll length, and customization level. Buyers should confirm exact MOQs and lead times with the manufacturer based on specific wire thickness, mesh opening, and roll dimensions required for their application.

Yes, knitted wire mesh can be engineered with density control ranging from near 0% to over 98% void volume, allowing virtually infinite porosity customization. This flexibility enables manufacturers to fine-tune pressure drop, filtration efficiency, and flow rate characteristics for filtration, separation, and mist elimination applications.
