AI-Powered supplier vetting

SummaryThe supplier operates in rail transit, high-speed rail equipment and accessories, new energy technologies, technical glass, fireproof sealing materials, and related special equipment. It reports extensive customization capability, OEM service for recognized brands, standardized finished-product inspection, and multiple quality, environmental, occupational-health, fire-protection, and EU certifications. Its company description states that it has served nearly a thousand major enterprises and achieved an average annual order delivery rate above 98%. However, the provided information indicates no valid manufacturing-capacity contract with an affiliated subcontractor, no inventory, overseas warehouse, overseas showroom, overseas agent or branch, or offline trade-show participation. Financial credibility cannot be assessed because the supplied financial fields contain zero values and no reliable supporting explanation.

Supplier typeThe supplier is positioned as a seller and developer of rail transit and high-speed rail equipment, rail transit green composite materials, new energy prime movers and technologies, technical glass, fireproof sealing materials, and special equipment. The scope indicates an industrial equipment and component supplier with research and development activities, rather than a general trading-only business.

CertificationsThe supplier reports ISO9001:2015, ISO14001, ISO45001, EU CE certification, 17 fire-protection product certificates issued by the Ministry of Emergency Management Fire Assessment Center, and more than 20 EU fire-resistant material certificates.

Its description also states that products can be customized according to actual needs, providing direct evidence of broad customization capability.

Client casesThe supplier states that it has long served nearly a thousand major enterprises and reports OEM service for recognized brands. It also cites extensive fire-protection and EU fire-resistant material certifications, but no specific customer names, project descriptions, or independently verifiable case details are provided.

Product Q&A

Q:How does the intumescent ventilation grille work?

Under normal conditions, the grille allows air to circulate through the opening. When exposed to high temperatures, the graphite-based intumescent core expands and helps restrict the passage of fire and smoke.

Q:What fire rating does this ventilation grille provide?

The available fire classification is E68 and E135 I57. The final rating depends on the grille size, installation method, supporting construction, and applicable test report.

Q:Which fire test standards does the product comply with?

The product has been tested according to EN 1634-1 / EN 1364-5 . Test reports and supporting documents can be provided upon request.

Q:Where can the grille be installed?

It is designed for approved ventilation openings in fire-rated doors, walls, and partitions. The installation location and method must comply with the applicable test report and project requirements.

Q:Can the size, shape, and finish be customized?

Yes. We can customize the dimensions, shape, frame finish, and installation configuration according to project drawings or samples. Please provide the required opening size and fire-rating requirement for evaluation.
