Jinyi duct systems

Board supply and completed ductwork are different enquiries

Jinyi’s steel-faced composite duct page and composite-board page share a general sales description. Their headings distinguish products, but the readable text does not provide the layers, thicknesses, joint details or tested dimensions needed to treat them as interchangeable assemblies. The distinction below is an enquiry boundary, not an assertion that the supplier owns every process. (Sources 2 and 3.)

The selected construction needs its own performance evidence

The reviewed steel-faced product page does not give a readable numerical fire-resistance classification, test-report number, pressure class or leakage result. No fire rating, thermal-conductivity value or permissible service temperature has been assigned to it in this profile. The neighbouring board page also uses general sales copy instead of a panel specification. (Sources 2 and 3.)

For a smoke-exhaust duct enquiry, request the original assembly report and compare its face/core construction, thickness, joint arrangement, dimensions, supports and installation orientation with the proposed system. A report concerning only a material or a differently constructed duct does not by itself establish performance of the ordered assembly. The website’s smoke-exhaust application category is a catalogue category, not a matched test result.

For central-air-conditioning use, the selected supply also needs an agreed pressure and leakage basis and any required insulation and moisture-control arrangement. Those project requirements should be answered with the supplier’s specific proposed construction. They are not published ratings of Jinyi’s products and should remain open until the quotation supplies supporting details.

What the independent list adds—and what it cannot add

The complete 39-page enterprise-list PDF was downloaded and read after the official pages. On page 34, row 1453 matches the company name and code above. The list’s columns concern enterprise identity and scale classification; this review does not derive plant output, quality, creditworthiness or a fire-product approval from that listing. A publication date was not established from the document itself. (Source 4.)

Do not import generic website copy into a factory biography

The home page includes wording about automation-related products and support that does not explain the listed duct construction. The specific company-introduction page has no substantive readable history. Those omissions are reflected here instead of filling the profile with a standard founding story, production-line inventory or capacity estimate. (Source 1.)

The actual composite-product pages promise contacts for pre-sales, sales and after-sales service, but do not set a geographical service boundary, installation scope or contractual response time. For a duct order, identify who prepares fabrication drawings, approves site dimensions and handles damage or changes after delivery. Keep those responsibilities in the quotation and handover record; do not assume installation support from a general service sentence.

Jinyi’s profile is consequently strongest as a documented supplier enquiry rather than a verified factory-capacity assessment. A plant address, fabrication evidence and a configuration-matched test package would materially strengthen it. Those records remain missing and have not been replaced by marketing claims from unrelated companies.
