Metal is unforgiving to source badly. Order from the wrong 'manufacturer' and you get a trader's markup on every tonne; get the grade, tolerance, or standard wrong and the metal is useless for your project. China has the mills — but finding the real producer, at mill-direct pricing, with the certificates to prove the spec, takes a search done in Chinese, on the ground.
We find and verify Chinese steel and metal manufacturers for serious buyers — HR/CR/GI coil, structural steel, pipe and tube, stainless and more. You get a shortlist of real mills matched to your grade and volume, with mill test certificates and factory-direct quotes.
Who this is for
This service is for:
- Importers buying HR/CR/GI coils, structural steel, pipe, or stainless who keep landing on traders.
- EPC and construction firms needing tender-ready supply with full specs and certificates.
- Buyers ordering container or 20 MT+ volumes who want mill-direct pricing, not a middleman's markup.

Steel grade cross-reference: GB, ASTM, EN, JIS and GOST
A Chinese mill quotes in GB grades. Your drawing, your customer or your customs classification is probably written in ASTM, EN, JIS or GOST. Most sourcing mistakes in metal start here — the grade sounds close enough, the certificate says something else, and the material is wrong for the job.
| Product / type | China (GB) | USA (ASTM / API) | Europe (EN) | Japan (JIS) | CIS (GOST) |
|---|---|---|---|---|---|
| Structural carbon steel | Q235B | A36 | S235JR | SS400 | Ст3сп |
| Low-alloy high-strength | Q355B (ex-Q345B) | A572 Gr. 50 | S355JR | SM490A | 09Г2С |
| Cold-rolled forming grade | DC01 / SPCC | A1008 CS | DC01 | SPCC | 08пс |
| Galvanised coil | DX51D+Z | A653 CS Type B | DX51D+Z | SGCC | ГОСТ 14918 |
| Austenitic stainless | 06Cr19Ni10 (304) | 304 / S30400 | 1.4301 | SUS304 | 08Х18Н10 |
| Molybdenum stainless | 022Cr17Ni12Mo2 (316L) | 316L / S31603 | 1.4404 | SUS316L | 03Х17Н14М2 |
| Rebar | HRB400 | A615 Gr. 60 | B500B | SD390 | А500С |
| Line pipe | L245 / L290 (GB/T 9711) | API 5L Gr. B / X42 | L245 / L290 | STPG370 | Ст20 |
These are the closest commercial equivalents, not identical materials: chemistry, tolerances and impact-test requirements differ between standards. Confirm the actual composition and mechanical properties on the mill test certificate before you order, and tell us which standard your buyer or inspector will test against. Note that GB/T 1591-2018 renamed Q345 to Q355 — older offers still quote the previous designation.
How we verify a real mill
A steel trader and a steel mill look identical in an email. The difference shows up in licences, certificates, and a factory floor — which is what we check before recommending anyone.
For volume orders, we arrange a mill audit so you know the capacity is real.
- Manufacturer status — a mill, not a trader
- Business licence and production scope
- Mill test certificates (MTC) for the grade
- Compliance with your standard (GB, ASTM, EN, etc.)
- Production capacity for your tonnage
- Export experience with metals
- On-site mill audit where the order justifies it
What a mill test certificate proves — and how to check it
A mill test certificate ties the steel in your container to a tested batch. It is also the document most often reissued, edited or simply invented somewhere between the mill and you. The type of certificate matters as much as the numbers printed on it.
Ask for it before the balance payment rather than after delivery. Every certificate carries a heat (cast) number, and that number should also appear on the coil tags or bundle labels — and, on plate and sections, on the steel itself.
- For structural and pressure work, 3.1 is the minimum a serious buyer accepts
- A certificate on a trading company's letterhead is not a mill certificate
- Confirm the heat number with the mill, not through the seller
- A portable spectrometer check on arrival settles any dispute about grade
- 2.1 — a declaration of compliance, carrying no test results at all
- 2.2 — a test report from routine production, not from your batch
- 3.1 — results from your batch, signed by the mill's own inspection unit
- 3.2 — the same, countersigned by a third party or your representative
- Heat number on the certificate must match the tags on the material
- Values must sit inside the grade's limits, not merely look plausible
From spec to shortlist
Metal sourcing starts with an exact spec, because a small difference in grade or tolerance changes everything. We turn your spec into a shortlist of mills that can actually meet it.
You get producers compared on price, certs, and lead time — not a pile of trader listings.
Where China's metal actually comes from
China's steel industry is regional, and the region tells you a lot before you ever see a quote. Flat products, long products and stainless are concentrated in different provinces, each with its own cluster of mills, processors and traders feeding off them.
It matters commercially: a seller offering every product from every category, at one address, is almost never a mill. Knowing where a grade is genuinely made is one of the fastest ways to sort producers from resellers.
- A quote from the wrong province for that product is worth a second look
- Inland mills can price well but add rail cost to the port
- Port proximity affects lead time as much as rolling schedule does
Lead times, Incoterms and what a metal quote includes
Two questions decide whether a metal offer is actually comparable: when it ships, and what the price already covers. Almost no supplier states either up front, which is why quotes that look 5% apart can be weeks and a whole freight leg apart in reality.
| From stock | Mill rolling | Custom or special | |
|---|---|---|---|
| Typical lead time | 1–2 weeks | 3–4 weeks | 4–8 weeks |
| Best for | Standard grades and common sizes | Volume orders to a standard spec | Non-standard grade, size, coating or certification |
| What sets the date | Availability at the mill or its warehouse | The mill's rolling schedule | Tooling, trial runs and testing |
We quote FOB by default, and can also quote CIF, DDP or EXW — and because we run the freight ourselves, we can price a landed cost to any port in the world rather than leaving you to add shipping afterwards. Ask for the Incoterm your accounting actually uses and compare like with like. Lead times start from confirmed order and cleared payment, not from first enquiry.
What actually drives the cost of metal from China
On a metal order most of what you pay is the mill's price per tonne, and that tracks the market rather than us — index, grade, coating, width and the mill's rolling schedule all feed into it. Our layer is the sourcing, verification and coordination around that price, quoted separately so you can see it instead of finding it buried in the tonne rate.
Two numbers decide whether an offer is actually good: the mill price and the freight. The second is where comparisons usually fall apart, because a quote FOB and a quote DDP are not comparable until somebody prices the leg in between.
- Tonnage, and whether it fills a container or a vessel parcel
- Grade and coating: commodity grades price close to index, special steels do not
- Whether the material is in stock or has to be rolled to order
- Port of loading and the Incoterm you work to
- Certification or third-party testing beyond a standard mill certificate
- Grade and the standard it must meet (GB, ASTM, EN, JIS, GOST)
- Dimensions and tolerance
- Tonnage, and whether the order repeats
- Coating class, if galvanised
- Destination port and your Incoterm
- Any inspection or third-party testing you require

Where metal sourcing goes wrong
The problem we solve — and how we solve it.
'Manufacturers' on Alibaba turn out to be steel traders adding a margin on every tonne.
We verify mill status before shortlisting, so you buy at the source.
Wrong grade or out-of-tolerance metal arrives, useless for your project.
We confirm grade, standard, and mill test certificates against your spec.
English-only search misses the mills and their domestic pricing.
We search and negotiate in Chinese with real producers.
Metal sourcing: agency, logistics company or Alibaba?
| Silk Way Sourcing | Typical logistics company | Alibaba sourcing | |
|---|---|---|---|
| Who you reach | Verified mills, direct | They don't source | Often steel traders |
| Specs & certs | Grade and mill certs confirmed | Not applicable | Listed, rarely checked |
| Pricing | Mill-direct | Not applicable | Trader markup per tonne |
| Shortlist | Real producers compared | None | You sift hundreds |
Buying steel from China: common questions
Do you find actual mills or traders?
Actual mills. We verify manufacturer status before shortlisting, so you buy mill-direct instead of paying a trader's per-tonne markup.
Can you confirm grade and certificates?
Yes — we confirm the grade and standard (GB, ASTM, EN, etc.) and obtain mill test certificates (MTC) so the metal matches your spec.
What metals do you source?
HR/CR/GI coil and sheet, structural steel, pipe and tube, stainless, wire and rebar, plus non-ferrous and specialty alloys on request.
Is there a minimum order?
Metal sourcing works best at volume — typically a container or ~20 MT+ — where mill-direct pricing makes sense. Smaller lots are usually traders' territory; we'll tell you honestly.
Can you check the mill in person?
Yes — for volume orders we arrange a mill audit to confirm capacity and that production is real.
Do you handle shipping for heavy metal cargo?
Yes — we can carry it through to freight, customs, and delivery, including the documentation heavy cargo needs.
Can you match a specific standard?
Yes — tell us the standard (GB, ASTM, EN, DIN, etc.) and we confirm the mill can produce and certify to it.
How do I know a mill test certificate is genuine?
Start with the type: EN 10204 2.2 is routine production data, while 3.1 covers your actual batch and is signed off by the mill's own inspection unit. Then check that the heat number on the certificate matches the tags on the coils and that the chemistry and mechanical values sit inside the grade's limits rather than merely looking plausible. Where the order justifies it, the surest confirmation is putting the heat number to the mill directly, plus a spectrometer check when the material lands.
How do I avoid 201 stainless being supplied as 304?
201 replaces most of the nickel in 304 with manganese and nitrogen, so it is noticeably cheaper and corrodes sooner. A magnet does not settle it, because both grades can turn slightly magnetic after cold working. The chemistry does: 304 carries around 8% nickel against roughly 1% in 201. Ask for the mill certificate with the heat number and confirm with a portable spectrometer or a lab analysis on arrival.
What does Z275 mean on galvanised steel?
It is the zinc coating weight under EN 10346: 275 grams per square metre counted across both surfaces together, which is roughly 20 microns per side. Z100 and Z140 are common lighter classes for indoor use. Buyers often read the figure as per side and end up with half the corrosion protection they expected, so state the coating class in the order and check it on the certificate.
How much does metal supplier search cost?
Most of what you pay on a metal order is the mill's price per tonne, which tracks the market rather than us. Our sourcing and verification layer is quoted separately, so you can see it instead of finding it inside the tonne price. Send the grade and standard, the tonnage, the destination port and the Incoterm you work to, and you will get a landed number you can actually compare against other offers.
