AI-Powered supplier vetting
SummaryZhejiang Zhong Ding Iron and Steel Co., Ltd. is a China-based limited trading company established in 2020 with 14 employees and a Ningbo, Zhejiang location. The supplier reports large-scale steel production integration, including 8 hot-rolling piercing lines and 30 cold-rolling units, with a stated production range beginning at 10 mm and extending to 219 mm. It has exported for four years, with exports representing 71%–90% of total sales, and has attended the Dubai Fair. The supplier reports new-product activity and sample-based customization, but has only one R&D engineer and does not provide ODM, well-known-brand OEM, or SDK services. No overseas agents, branches, warehouse, showroom, or in-stock service capability are reported. Financial records are referenced for 2022–2024, but no financial results are provided. Evidence is insufficient to confirm certifications, documented quality assurance, raw-material traceability, or customer cases.
Supplier typeThe supplier is identified as a trading company and limited company, while its description states that it integrates production, sales, and trade. Its registered location is Ningbo, Zhejiang, China, and its business scope includes technology import and export, import and export agency, and goods import and export subject to applicable approvals.
R&D capabilityThe supplier reports one R&D engineer and new products launched during the past year. It does not provide ODM services, well-known-brand OEM services, or SDK availability, indicating some product-development activity but limited documented breadth of innovation services.
Production capacityThe company description reports 8 hot-rolling piercing production lines and 30 cold-rolling units, with a stated production range of 10 mm to 219 mm. However, the supplier also reports no in-stock capacity, while outsourcing procedures and manufacturing-capacity contracts are unknown; the stated production infrastructure nevertheless provides explicit evidence of production capability.
Customization capabilityThe supplier explicitly offers customization from samples and reports product R&D activity. At the same time, it does not offer ODM services, so the evidence supports sample-based customization but not broader independent design or ODM capability.
Product Q&A
Q:When to use 316L vs. 316?
A:
316L for welding or extreme corrosion (e.g., welded pipelines). 316 for non-welded, high-strength needs.
Q:Can 316 stainless steel rust?
A:
Rarely, but prolonged exposure to extreme chlorides (e.g., undiluted bleach) may cause pitting.
Q:How to identify 316 pipes?
A:
Check markings ('316'/'S31600') or Mill Test Certificates (MTC). A molybdenum test (e.g., XRF analyzer) can confirm.
