AI-Powered supplier vetting

SummaryTianjin TianYingTai (TYT) Steel Pipe Co., Ltd. is a combined steel manufacturing and processing supplier with stated experience of 18 years, 13 steel-pipe production lines, 10 processing lines, and two hot-dipped galvanizing lines. Its business scope covers steel rolling, metal structures and materials, metal-product R&D, and photovoltaic equipment sales. The supplier holds ISO9001:2015, ISO14001:2015, and ISO45001:2018 certifications, and reports quality assurance and inventory capacity. However, it has no available SDK, no overseas warehouse, showroom, agents, or branches, and no participation in offline trade shows. Manufacturing capacity is not fully verifiable because no valid contract with related subcontractors is reported. Financial records are referenced by year, but no substantive financial results are provided. Formal complaint-handling, corrective-action, and approved-supplier procedures are also absent from the evidence.

Supplier typeThe supplier is identified as a combined company engaged in steel production, sales, processing, greenhouse engineering, export, and related metal-product activities. Its stated business scope also includes steel rolling, metal structures, metal materials, metal-product R&D, and photovoltaic equipment and component sales, indicating a manufacturer with integrated processing and trading activities.

CertificationsThe supplier reports ISO9001:2015 and ISO45001:2018 certificates, as well as ISO14001:2015 certification and other certifications. These explicitly demonstrate certified quality, environmental, and occupational-health-and-safety management coverage.

Production capacityThe supplier reports 18 years of experience, 13 steel-pipe production lines, 10 processing lines, two environmental hot-dipped galvanizing lines, and inventory capacity. However, it also reports no valid manufacturing-capacity contract with associated subcontractors, while another record states seven production lines, so the full capacity profile is not entirely consistent.

Customization capabilityThe supplier explicitly provides steel processing, metal-structure manufacturing, metal-material manufacturing, and greenhouse engineering with accessories, supported by its own factory and processing center. These activities demonstrate relevant processing and product adaptation capability, although specific customization examples or limits are not provided.
