Quality
Verification you can repeat at your own goods-in
We do not ask you to trust adjectives. Every shipment passes the checks below before cartoning — and we publish the same checklist so your inspector can repeat it on arrival.
Before it leaves Baoji
| Check | Method | Accept |
|---|---|---|
| Diameter | Caliper / micrometer sampling per lot | h7 class per order specification |
| Length | Sampling against gauge | ±1 mm |
| Colour band | Visual vs ISO 6848 designation on label | Exact match, no unpainted rods |
| Surface & straightness | Visual + roll test sampling | Ground finish, no chatter marks, rolls true |
| Packing count | 100% box count, photographed row | 10 or 20 pcs per box as ordered |
| Carton marking | Label vs packing list | Type, size, qty, standards stated |
Your incoming inspection checklist
- Caliper three rods per box at mid-length; compare to the h7 band on your PO.
- Read the text designation on the label — then confirm the band colour matches ISO 6848.
- Roll five rods on glass: no wobble, no visible chatter marks.
- Count one box per carton fully; spot-count two more.
- Weld-test one rod per type at your working current: note first-arc start and re-start behaviour.
- File the photos of labels next to your goods-in record — they are your traceability chain.
Certificates of analysis accompany shipments on request; as a supplier with multiple production lines, our documents state the verified result per lot rather than a generic promise.
