• Weaving (Woven Mesh): Precision weaving looms are used to interlace the warp (longitudinal) and weft (transverse) wires. Common weave types include plain weave, twilled weave, and various forms of Dutch weave. The loom ensures consistent mesh count and aperture size.
• Welding (Welded Mesh): For applications requiring greater rigidity and strength, individual SS 316 wires are resistance welded at their intersections. This process ensures robust joints and a highly stable mesh structure.

3. Finishing and Treatment:

• Cleaning: The woven or welded mesh undergoes thorough cleaning, often involving degreasing and pickling, to remove contaminants, lubricants, and oxides from the surface.
• Passivation: A crucial step for stainless steel, passivation involves treating the mesh with an acid solution (e.g., nitric acid) to remove free iron from the surface and enhance the chromium oxide layer. This significantly boosts corrosion resistance.
• Cutting and Fabrication: The finished mesh is cut to specified dimensions, rolls, or panels. Further fabrication like calendering (flattening for increased stability) or forming into filters, baskets, or architectural elements may occur.

4. Quality Control and Testing:

Throughout the process, and especially after finishing, rigorous testing is conducted to ensure compliance with international standards and client specifications.

• Dimensional Accuracy: Mesh count, wire diameter, and aperture size are verified using optical comparators and precision gauges (e.g., in accordance with ISO 9044 or ASTM E2016).
• Material Composition: X-ray fluorescence (XRF) or other spectrographic methods confirm the SS 316 chemical composition.
• Mechanical Properties: Tensile strength and elongation tests ensure the mesh meets required load-bearing capabilities.
• Corrosion Resistance: Salt spray tests or immersion tests may be performed to validate the passivation effectiveness and inherent corrosion resistance.
• Surface Finish Inspection: Visual and microscopic inspection for defects, burrs, or inconsistencies.
