Factory and Quality Verification for Cold Drawn Steel Buyers
Junxiong Metal is the export-facing brand for cold drawn steel enquiries. The cold drawn steel production facility and ISO 9001 certificate holder shown on this page is Wuxi Dishang Profile Steel Technology Co., Ltd., located in Wuxi, Jiangsu, China.
Scope: this page explains supplier identity, quality-system evidence and the documents a buyer should request. It does not certify a particular heat, grade, size, tolerance or finished component.
Short Answer
For cold drawn round, flat, square, hexagonal and custom steel profiles, buyers should verify both the production entity and the order-specific evidence. Wuxi Dishang holds the ISO 9001:2015 quality management certificate shown below for the production of cold drawn steel. A quotation or purchase order should still define the governing standard, grade, dimensions, tolerance, inspection method, traceability and required material documents.
Company and Production Relationship
- Export-facing brand: Junxiong Metal
- Production company: Wuxi Dishang Profile Steel Technology Co., Ltd.
- Factory location: No. 3, Wandong Road, Huishan District, Wuxi City, Jiangsu Province, China
- Production scope: cold drawn steel bars and drawing-based profiles
- Core forms: round, flat, square, hexagonal and custom solid sections
Commercial documents should state the applicable contracting entity and the ordered specification. A website brand, production company, certificate holder and invoice entity are not automatically interchangeable without confirmation.
ISO 9001 Quality Management System Certificate
- Standard shown: GB/T 19001-2016 / ISO 9001:2015
- Certificate scope shown: production of cold drawn steel
- Issue date shown: October 28, 2025
- Expiry date shown: October 27, 2028
The certificate image includes an annual-supervision-audit notice. Before placing an order, a buyer may request the current certificate copy and any required order-specific documents. The certificate shown is quality-management-system evidence; it is not a material test certificate for a specific steel heat or batch.
Official Standard and Certificate-Verification Routes
- ISO 9001:2015 official publication page: confirms the quality-management-system standard and provides its current revision and transition information. It does not validate this individual certificate.
- IAF CertSearch listing for FAP Certification (Shanghai) Co., Ltd.: identifies the certification body and its public ISO 9001 accreditation scope, including basic metals and fabricated metal products. It is an issuer-level reference, not an exact certificate-number result.
- IAS MSCB-294 issuer record: identifies FAP as accredited, but at the 15 September 2026 review it also displayed an expiry date of 1 September 2026. Because those public fields conflict, buyers should request current issuer confirmation rather than infer status from either field alone.
- ISO 10474:2013 official publication page: defines inspection-document types supplied according to an order for steel products. The buyer must still state the required document type in the RFQ and purchase order.
Verification status: the exact certificate number shown above was not available as a directly retrievable public certificate record in the accessible issuer or accreditation directories during the 15 September 2026 review. This does not establish that the certificate is invalid; it means independent online verification of this individual certificate remains incomplete. Buyers may request the current certificate copy, issuer verification route and order-specific inspection documents before purchase.
Technical Facts and Evidence Boundaries
| Evidence | What it supports | What still needs order-specific confirmation |
|---|---|---|
| ISO 9001 certificate | Quality-management system and stated production scope | Current validity, certificate holder and purchase-order entity |
| Material test certificate (MTC) | Ordered heat or batch data when agreed | Applicable standard, chemistry, property limits and document type |
| Dimensional inspection report | Agreed size, tolerance, straightness or profile features | Sampling plan, reference datum and measurement method |
| Product or packing photograph | Representative shape, handling or export-packing evidence | Grade, heat number, exact dimension and final application suitability |
Grade-Specific Document Routes
A photograph, trade designation or quality-system certificate does not identify an ordered heat. Use the relevant material page to define the governing standard, product form and application, then state the required heat-specific MTC and inspection records in the RFQ.
| Material enquiry | Buyer verification route |
|---|---|
| 1215 / 12L14 free-machining round bar | Confirm grade route, diameter, tolerance, heat traceability and MTC wording |
| 35K / SWRCH35K actuator rod blank | Confirm the buyer drawing, application approval, standard and batch documents |
| 35K / SWRCH35K lead-screw shaft blank | Confirm the thread-forming route, heat treatment, dimensions and MTC |
| 430F / SUS430F / 1.4104 machining bar | Confirm the exact designation, governing standard, shape, condition and heat certificate |
For quotation, send the grade, standard, shape, dimensions, tolerance, length, quantity, destination, end use and required documents through the technical RFQ form.
Representative Factory and Inspection Evidence
Documented 10 x 40 mm Flat Steel Sample Records
The records below cover separate 10 x 40 mm samples and application checks: a restricted-substance report for a 1215 sample, a mechanical and hardness report that does not name the grade, and a welding-strength report for a Q235 joint sample. They do not form one same-batch MTC chain and do not certify 12L14, 35K, SWRCH35K, 430F or any other unlisted grade or batch.
| Record | Verified scope | Buyer action |
|---|---|---|
| Width and thickness inspection | Representative 10 mm thickness and 40 mm width checks | Define tolerance, sampling plan and measurement method in the RFQ |
| RoHS chemical compliance report | Restricted-substance evidence for the documented 10 x 40 mm 1215 sample | Do not treat it as grade chemistry or an MTC; request a heat-specific MTC for a new order |
| Mechanical and hardness report | Mechanical-property and hardness evidence for a documented 10 x 40 mm flat-steel sample; the report does not name a grade | State the required grade, limits and test frequency before production |
| Welding-strength report | Application-test evidence for the documented 10 x 40 mm Q235 joint sample | Confirm weld design, acceptance criteria and finished-part responsibility |

Buyer Checklist Before Issuing a Purchase Order
- State the exact steel grade and governing standard.
- Attach a drawing or specify round, flat, square, hexagonal or custom section.
- Define all critical dimensions, tolerance, straightness, twist and corner-radius requirements.
- State random or fixed length, end condition and any agreed secondary processing.
- Define MTC, heat traceability, chemical, mechanical, hardness or dimensional-report requirements.
- State quantity, destination country, packing requirement and required delivery term.
Frequently Asked Questions
Does the ISO certificate prove that every bar meets a specific grade?
No. It supports the stated quality management system and production scope. A specific grade, heat and batch require the governing purchase specification and agreed MTC or inspection records.
Can a buyer request chemical, mechanical or dimensional records?
Yes. State the required document type, acceptance criteria and inspection scope before production so the quotation and inspection plan can be reviewed.
Who should be named on commercial documents?
Confirm the contracting and invoice entity before order placement. The website brand, production company and certificate holder should be matched to the buyer’s compliance and purchasing requirements.
Request a Document and RFQ Review
Send the grade, standard, bar shape, size, tolerance, quantity, destination and required certificate or inspection documents for a factory feasibility review.
