Incoming wire-rod inspection — where quality begins
The quality of drawn wire begins at the wire-rod entrance to the plant. Every rod coil should be inspected before it enters the drawing bays: mill certificate cross-checked, hardness verified independently, surface examined, and any anomaly logged. Rod that does not meet spec should never enter the process.
On our line, incoming rod comes from a small, stable list of mills — when one changes their steelmaking practice, we know within a week.
Drawing die maintenance — the unglamorous discipline
Drawing dies are consumables. How a supplier maintains them decides three things: surface quality on the wire, drawing energy per tonne, and yield. A serious supplier inspects and rotates dies on a fixed schedule and pulls a die out of service the moment its wear signature shifts.
Running dies to failure produces a shift-worth of bad wire before anyone notices. Ask your supplier how they schedule die maintenance.
In-process tensile monitoring and diameter control
Tensile scatter within a single coil is the technical variable that most affects downstream customers. A coil where every metre reads within a narrow tensile band lets a header or a bender run without adjustments. Look for suppliers who monitor tensile in-process, not only at final inspection.
Diameter should be verified continuously — modern lines use laser gauges — and any deviation should trigger a hold, not a note.
Final coil inspection and traceability
Every finished coil should be inspected for surface, diameter, tensile and packaging integrity before it leaves the warehouse. Every coil should carry a tag with heat number, cast number, lot number and production date. That data should be retrievable years later when a customer asks about a warranty question.
See ourcertifications and documents page for how we present traceable documentation.
The paper trail: EN 10204 3.1 as the audit output
All of the above should culminate in an EN 10204 3.1 inspection certificate — an independent, specific document that ties chemistry, mechanical properties and dimensional data to the actual heat you received. If the paper trail is thin or generic, treat the quality control as suspect. Ask for a sample 3.1 certificate as part of the supplier evaluation.
Frequently asked questions
Do you supply EN 10204 3.1 inspection certificates by default?
Yes. Every export shipment travels with an EN 10204 3.1 inspection certificate showing chemistry, tensile properties and dimensional data for the actual heat. This is our default, not a paid add-on.
What are your typical lead times for EU and US buyers?
Standard grades ship 2–4 weeks from PO confirmation. Add 5–10 days sea freight to European destinations and 20–25 days to US East Coast under normal conditions. Custom grades or specialty packaging may extend production time.
Can you handle small trial orders before volume commitment?
Yes. We support new customers with sample lots and small trial orders — typically 1–5 tonnes — before ramping to volume. Contact our quote desk to arrange a sample.
What documentation do you provide for EU and US customs clearance?
For EU shipments we provide A.TR movement certificate to support duty-free entry under the EU-Turkey Customs Union. For US shipments we provide certificate of origin and any HS-code-specific documentation required. Discuss requirements with our export desk.
