What it is
Wire rod is hot-rolled low-carbon steel in coil form, drawn down into wire, mesh, nails, fasteners, and welding electrodes. Chemistry consistency matters more than for structural steel because downstream drawing amplifies any defect.
Grades & standards buyers order
| Grade | Standard | Notes |
|---|---|---|
| SAE 1008 / 1006 | ASTM / SAE | The workhorse low-carbon drawing grades. |
| Q195 / Q235 | GB/T 701 (China) | Chinese general-purpose rod grades. |
| H08A | GB | Welding-wire grade with tight chemistry limits. |
How it's sold: Sold by metric ton in coils of 5.5mm–14mm diameter, typically 2 tons per coil. Check coil weight consistency and rust protection for the transit route.
What drives the price
- Billet cost and carbon content
- Coil weight and uniformity
- Surface quality (critical for fine drawing)
- Packaging and rust prevention for sea freight

Exact chemistry (C, Mn, S, P)
Drawing failures trace back to chemistry; a certificate must show the actual heat analysis.
Rod diameter tolerance
Out-of-round rod jams drawing dies and is a hidden quality cost.
Coil weight
Underweight coils invoiced at nominal weight is the quiet loss on rod orders.
Scams most common to wire rod
Grade Substitution (lower grade shipped than ordered)
Higher-carbon or off-chemistry rod shipped as a clean drawing grade, only discovered when wire snaps.
Forged Mill Test Certificates (MTC / EN 10204 3.1)
Heat analysis on the certificate that does not match the coil actually shipped.
Coating-Weight & Galvanizing Fraud
For galvanized wire products, thin zinc invoiced as heavier coating.
Red flags in a quote or sample
- No heat-analysis chemistry on the certificate
- Vague "low carbon" grade with no SAE/GB reference
- Rust-prone packaging quoted for a long sea route
Already paid and something's wrong?
If you received off-spec wire rod, a certificate that doesn't match, or your supplier has gone quiet after a deposit, move quickly. Recovery odds drop with every day that passes on a wire transfer.
Buying wire rod from China: FAQ
What grades of wire rod can I buy from China?
The most commonly ordered grades are SAE 1008 / 1006, Q195 / Q235, H08A. Always pair the grade with its standard on the purchase order so the mill test certificate can be matched to what you actually receive.
What is the most common scam when buying wire rod from China?
Grade Substitution (lower grade shipped than ordered). For this product specifically: Higher-carbon or off-chemistry rod shipped as a clean drawing grade, only discovered when wire snaps. The defense is to specify the exact grade and standard, require a verifiable mill test certificate, and commission independent pre-shipment inspection.
What should I check before paying for wire rod?
Lock down exact chemistry (c, mn, s, p), rod diameter tolerance, coil weight in the contract, verify the supplier is a real manufacturer, and never release the balance until an independent inspection confirms the goods.
I already paid a Chinese supplier for wire rod — what now?
Act fast: contact your bank about a recall on the wire, gather all contracts and communications, report the pattern so others are warned, and review the documented cases to understand your options. The sooner you act on a redirected or disappeared payment, the better the odds.
