| 1 | Mesh Opening | A standard 358 fence uses approximately 76.2 mm horizontal spacing × 12.7 mm vertical spacing, commonly described as a 3 in × 0.5 in mesh. | The narrow opening makes the panel difficult to climb and limits the passage of common hand tools. | Confirm the opening size by measuring clear distances between adjacent wires after welding. State tolerances on the purchase specification. |
| 2 | Wire Diameter and Steel Grade | The commonly supplied wire diameter is about 4.0 mm, approximately equivalent to 8 gauge in some gauge systems. Low-carbon welded steel wire is widely used, but the exact chemical and mechanical requirements must be specified. | Wire diameter affects cutting resistance, panel rigidity, weight, freight cost, and post-load performance. | Request a dimensional inspection report and, where required, a mill test certificate under EN 10204. Do not rely on gauge designation alone because gauge systems can differ. |
| 3 | Panel Height, Width, and Tolerance | Common project heights are approximately 1.8 m to 3.0 m; panel widths are often around 2.0 m to 2.5 m. These are market conventions, not universal standards. | Panel dimensions must match posts, gates, foundations, transport limits, and the required security level. | Approve a dimensioned drawing showing panel length, height, wire diameter, post spacing, fixing points, and permitted tolerances before production. |
| 4 | Corrosion Protection | Typical options include zinc-coated wire, welded panels galvanized after welding, or zinc-coated steel with an additional organic coating. Hot-dip galvanizing of fabricated steel articles can be specified with ISO 1461; wire coating requirements may be specified with EN 10244-2. | Coating method and coating mass influence service life, especially in coastal, humid, industrial, or de-icing-salt environments. | Specify the applicable standard, coating type, coating mass or thickness, salt-spray requirement if relevant, and visual acceptance criteria. Confirm that cut edges and weld areas are adequately protected. |
| 5 | Product and Quality Standards | For welded steel fence panels, buyers may reference EN 10223-7 where applicable. Zinc-coated steel wire may be specified with EN 10244-2, and fabricated hot-dip galvanized steel components may reference ISO 1461. The selected standard must match the product and destination market. | A standard provides a common basis for dimensions, coating, testing, inspection, and acceptance. | Put the exact edition and applicable clauses in the contract. Confirm whether local building, perimeter-security, fire, or infrastructure rules impose additional requirements. |
| 6 | Certifications and Inspection Documents | Commonly requested documents include a product specification, inspection report, coating test results, material traceability documents, and an EN 10204 3.1 inspection certificate when material verification is required. ISO 9001 is a quality-management certification, not proof that every fence meets a specific product standard. | Correct documentation helps customs clearance, project approval, warranty review, and third-party inspection. | Check certificate scope, issuing body, certificate validity, batch or heat numbers, test methods, and consistency with the purchase order. Do not treat a general management certificate as a product-performance certificate. |
| 7 | Export, Packaging, and Customs Requirements | Prepare a commercial invoice, packing list, transport document, and certificate of origin when required. The appropriate HS classification depends on the product construction and coating; welded iron or steel mesh is commonly considered within HS heading 7314, but the final code must be confirmed with the destination customs authority or broker. | Accurate classification, packaging, and documents reduce customs delays, unexpected duties, corrosion during transit, and cargo damage. | Confirm Incoterms, importer-of-record responsibilities, duties, marking rules, pallet dimensions, gross and net weight, container loading plan, moisture protection, and destination-specific labeling before shipment. |
