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.

Product Q&A

Q:What are the available sizes for the galvanized steel pipes?

The outer diameter (OD) ranges from 1/2 to 16 inches (21 to 406mm), with thickness from 1.2 to 30mm. Lengths include 3, 4, 5.8, 6, 8, 9, 11.8, and 12 meters, or custom sizes per contract.

Q:How is the zinc coating applied and what is its thickness?

The pipes undergo hot-dip galvanizing after acid pickling and cleaning. The zinc layer is 200-300g/m2 (about 30-40um thick), ensuring uniformity, strong adhesion, and excellent corrosion resistance.

Q:What is the typical delivery time?

The date of delivery is generally 15-30 days after payment is received.

Q:What inspection processes are performed on the products?

Inspections include chemical component analysis, mechanical and technical properties testing, exterior size inspection, and hydraulic testing to ensure quality.

Q:Do you supply pipe fittings along with the steel pipes?

Yes, we also supply pipe fittings such as screws and flanges to complement the steel pipe orders.
