Surface Treatment
| Surface Type | Description & Process | Coating Thickness | Key Characteristics |
|---|---|---|---|
| Bright/Bare Wire | Clean, drawn wire with a smooth, metallic finish. No additional coating. | N/A | Economical; for indoor, dry environments; requires immediate use or oiling to prevent rust. |
| Electro-Galvanized | A thin, uniform layer of zinc applied via electrolysis. | 5 - 15 g/m² | Good basic corrosion resistance; smooth & bright surface; suitable for electroplating. |
| Hot-Dip Galvanized | Wire is dipped in molten zinc, creating a thick, robust alloy layer. | 30 - 60 g/m² | Excellent corrosion resistance; characteristic spangled (crystalline) finish; thicker coating. |
| PVC/PE Coated | A layer of Polyvinyl Chloride or Polyethylene fused over a galvanized substrate. | 0.2 - 0.8 mm | Superior protection & color options; resistant to chemicals, abrasion, and UV rays. |

Quality Control
Quality is controlled at every stage, not just inspected at the end.
A. Incoming Raw Material Inspection
Process: We source wire rod from reputable mills.
QC Check: Verify material grade (e.g., 70#, 82B) and chemical composition against standards. This ensures the foundation of our product is solid.
B. In-Process Control
Process: Wire Drawing & Heat Treatment.
QC Check:
Dimensional Accuracy: Laser micrometers continuously monitor diameter tolerance.
Mechanical Properties: On-site tensile testing machines check tensile strength and elongation.
Torsion & Wrap Tests: Samples are regularly tested for ductility and surface integrity.
C. Final Product Audit
Process: Before packaging and shipment.
QC Check:
Surface Inspection: Visual and automated checks for cracks, scratches, or coating defects.
Coating Thickness: Measured using electronic gauges to ensure compliance (e.g., for galvanized wire).
Final Lab Testing: A final round of tests in our in-house lab to confirm all mechanical properties meet the order specifications.
D. Certification & Traceability
Process: Documentation and release.
QC Check: We generate a Mill Test Certificate (MTC) compliant with EN 10204 3.1 for every shipment, providing full traceability and proof of quality.
