PUBLIC COMPANY EVIDENCE · REVIEWED 5 SEPTEMBER 2026
YINONG Public Evidence Center for Overseas Buyers
Start with the official source, then match every claim to the correct entity, document and project.
This page identifies YINONG’s public website, contact route, document status and project-specific verification rules. A web page can provide a starting point; the quotation, drawings, bill of materials and contract must identify who is responsible for each part of a real project.
YINONG public source record
Public brand: YINONG STEEL STRUCTURE. Official domain: yinongsteelstructure.com. Company-history source: About YINONG. Current contact route: Contact YINONG.
The website history includes Shanghai Yinong Steel Structure Co., Ltd. Confirm the specific legal seller and manufacturer in the project documents. Historical certificates retain their archive status.
01 · PUBLIC STARTING POINTS
Use the official domain and contact route first

Company background
The About page provides the site’s public company history, factory gallery and document references.

03 · PUBLIC DOCUMENT STATUS
Read the holder, scope and date before relying on a document
| Public record | Status on this website | Safe use |
|---|---|---|
| RoHS Certificate of Conformity | Scope-limited | Check the named holder, report number, issue date, standard and covered items. Do not extend the result to unrelated items or projects. |
| ISO 9001 archive | Historical archive | The website states that the certificate period ended on 17 August 2024. It is historical reference, not proof of current certification. |
| ISO 14001 archive | Historical archive | The website states that the certificate period ended on 17 August 2024. Request a current certificate if it is required. |
| YINONG brochure | Marketing reference | Use it to understand background and categories. A brochure is not a contract specification, current inventory statement or delivery commitment. |
04 · PROJECT RESPONSIBILITY
Run the same six checks for every quotation
- Contracting entity. Match the legal name, registration details, address, bank beneficiary and authorized signatory.
- Manufacturing entity. Identify the factory that will perform the work and which parts, if any, will be subcontracted.
- Scope and specification. Attach the approved drawings, bill of materials, exclusions, applicable codes and acceptance criteria.
- Document applicability. Match each certificate or test report to its holder, location, standard, date and covered scope.
- Quality responsibility. Define inspection points, material traceability, records, third-party inspection rights and non-conformance handling.
- Delivery responsibility. State packing, Incoterm, transport, unloading, installation support, warranty and after-sales boundaries.

06 · BUYER FAQ
Questions buyers often ask
Does a company website prove who will manufacture my order?
No. The website is a public starting point. The quotation and contract should identify the legal counterparty, manufacturing location, subcontracted work and responsibility for quality and delivery.
How should I check a certificate?
Check the holder, issuer, certificate or report number, standard, scope, site address, issue and expiry dates, and whether it applies to the exact work being purchased.
Can an expired certificate be used as a current qualification?
No. An expired record may document historical activity, but it does not prove current certification. Request a current document and verify it with the issuer when the qualification matters.
What should control if a brochure and quotation differ?
The agreed project record should control: signed quotation or contract, approved drawings, BOM, specifications, exclusions, change orders and acceptance criteria.
