AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company whose scope covers metal materials, metal structures and products, mechanical equipment, hardware, special steel, chains, construction reinforcement products, building materials, mechanical components, and non-ferrous alloys. It offers flexible customization, ODM services, and OEM services for popular brands, but has only one R&D engineer and no SDK. Quality assurance is stated, although finished-product inspection is based on random checks and packing-staff inspection, with one quality inspector and no raw-material traceability. No management-system certification is reported. Overseas service infrastructure is limited, with no overseas showroom, agents, branches, or offline trade-show participation. Financial records are indicated for 2022–2024, but no financial results are provided.

Supplier typeThe supplier is explicitly classified as a Trading Company. Its listed business scope covers a broad range of metal materials, structures, products, machinery, hardware, construction materials, and components, indicating a trading-oriented supplier rather than an explicitly identified manufacturer.

Product Q&A

Q:What standards and grades do your carbon steel pipes comply with?

Our carbon steel pipes meet major international standards including ASTM A53/A106, 5L, and GB/T 8163/9711. Common grades include A106 Gr.B, A53 Gr.B, 5L Gr.B, Q235B, and Q345B, suitable for oil & gas, structural, and industrial piping applications.

Q:Can you provide customized sizes and surface treatments?

Yes, we offer full customization services. We can produce custom outer diameters, wall thicknesses, and lengths, as well as provide surface treatments like black painting, anti-rust oil, hot-dip galvanizing, 3PE/epoxy coating to meet anti-corrosion and project-specific requirements.

Q:Do you provide test certificates for the pipes?

Absolutely. All our carbon steel pipes come with 100% original mill test certificates (MTC), including chemical composition, mechanical properties, and dimensional inspection reports, to ensure full traceability and compliance with your order specifications.

Q:What is your lead time and delivery capability?

We maintain a large stock of standard sizes (Sch 40/Sch 80/Sch 160) for immediate delivery. For custom orders, the typical lead time is 15-30 days based on quantity and specifications. We can arrange sea freight to most ports worldwide, with full documentation support.

Q:How do you control the quality of your carbon steel pipes?

We implement strict quality control at every stage: raw material inspection, production process monitoring, non-destructive testing (NDT), and final third-party inspection (if required). This ensures our pipes meet the required tolerance, strength, and anti-corrosion standards before shipment.
