Large Diameter Capability: Produces large diameter pipes from narrow strip steel, ranging from 159mm to 3200mm.
High Pressure Resistance: Spiral seam stress is 75-90% of straight seam, allowing 10-25% thinner wall thickness under same pressure.
Precise Dimensional Accuracy: Diameter tolerance within 0.12%, deflection less than 1/2000, and ovality under 1%.
High Metal Utilization: Continuous production reduces head and tail loss, increasing metal utilization rate by 6-8%.
Flexible Customization: Length and processing services (bending, welding, cutting) customizable per customer requirements.
Versatile Coating Options: Surface treatments include FBE, 2PE, 3PE, 3PP, and varnish for corrosion protection.
Efficient Production Capacity: One unit equivalent to 5-8 sets of straight seam equipment for high quality and efficiency.

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.
