| 1 | Stainless Steel Grade | The manufacturer should clearly identify grades such as 304, 304L, 316, or 316L according to the application, corrosion environment, temperature, and forming requirements. | Material certificate, chemical composition report, heat number, and product marking records. | Compare the certificate grade and heat number with the purchase order and, where necessary, arrange independent alloy verification. |
| 2 | Applicable Wire Cloth Standard | Industrial woven wire cloth should be manufactured and inspected with reference to recognized standards such as ISO 9044 or ASTM E2016. | Quality-control procedure, inspection checklist, and standard referenced in the quotation or technical specification. | Confirm whether the stated standard covers mesh count, aperture, wire diameter, tolerances, and inspection methods. |
| 3 | Mesh Count and Aperture | The supplier should be able to produce commonly requested square, plain-weave, twill-weave, and Dutch-weave specifications with controlled aperture dimensions. | Mesh-count records, aperture measurement results, sample photos, and a dimensional inspection report. | Measure the sample with a calibrated optical instrument or microscope instead of relying only on visual inspection. |
| 4 | Wire Diameter Control | Wire diameter should match the approved specification because it directly affects open area, strength, filtration accuracy, and finished weight. | Wire-diameter range, calibration records, incoming-wire inspection data, and finished-product test results. | Check several positions across the sheet or roll, including the edges, and compare readings with the approved tolerance. |
| 5 | Dimensional Accuracy | The manufacturer should control sheet length, width, flatness, squareness, roll length, and edge condition according to the agreed drawing or purchase specification. | Final inspection report, measuring-tool calibration records, packing list, and approved dimensional drawing. | Use a sampling plan based on order size and inspect both the first article and random production pieces. |
| 6 | Mechanical Integrity | Mesh should have stable weaving, consistent tension, secure selvage, limited broken wires, and no unacceptable deformation during handling. | Visual inspection standard, tensile or strength test data where applicable, and nonconformance records. | Inspect the weave under magnification and perform a handling test on sample sections before approving mass production. |
| 7 | Surface Cleanliness and Corrosion Protection | The surface should be free from oil, loose particles, rust contamination, and serious weaving marks. Passivation or cleaning requirements should be defined when required by the application. | Cleaning procedure, passivation specification if applicable, surface inspection report, and packaging protection method. | State whether the mesh will be used in food processing, chemical service, filtration, or outdoor environments and approve the surface condition accordingly. |
| 8 | Traceability and Quality System | A reliable factory should maintain traceability from stainless steel wire input through weaving, inspection, packing, and shipment. An ISO 9001-based quality system is a useful management indicator. | Quality certificate, batch number, production records, corrective-action procedure, and inspection traceability documents. | Verify that the certificate is valid and that batch records can be linked to the actual shipment rather than only to a company profile. |
| 9 | Sampling, Testing, and Pre-Shipment Inspection | The supplier should accept pre-production samples, first-article approval, agreed acceptance criteria, and independent or buyer-appointed inspection when required. | Approved sample, inspection and test plan, certificate of conformity, inspection report, and sample-retention policy. | Put mesh count, wire diameter, aperture, dimensions, material grade, quantity, and defect limits directly into the purchase contract. |
| 10 | Packaging, Logistics, and Commercial Reliability | Sheets should be protected against bending, moisture, contamination, and impact. Rolls should be securely wrapped and labeled with specification, quantity, batch, and destination details. | Packaging photos, packing specification, shipping marks, lead-time commitment, and records of export documentation. | Request a packaging sample or detailed photos, confirm Incoterms and lead time, and use a written procedure for handling shortages or transit damage. |
