Mill-Backed Supply with Stockist Flexibility
Wenzhou Xinzhe Tech Co., Ltd. is a China-based stockist and supplier of seamless stainless steel, duplex, super duplex, and nickel alloy pipes and tubes, founded in 2019 in Wenzhou, Zhejiang Province. Backed by direct manufacturing capacity through our affiliated factory, Zhejiang Xintongda Special Steel Manufacturing Co., Ltd. (XTD Special Steel), Xinzhe combines the flexibility of a trading and stocking company with the production control, quality traceability, and cost advantages of a mill-direct source.
This dual structure allows Xinzhe to offer both off-the-shelf availability for standard sizes and grades, and mill-direct production for custom specifications, non-standard dimensions, and project-based orders — without the markup and lead-time uncertainty typical of pure trading companies.
Manufacturing Strength Behind the Stock
Because Xinzhe’s supply is rooted in XTD Special Steel’s production facility, every order can be backed by full production traceability, from raw material certification through final testing — rather than relying on third-party sourcing with limited visibility.
This is a key point of difference versus typical Chinese trading companies that resell inventory of unknown or mixed origin.
Quality Assurance
Every order is supported by complete mill test certificates and full production traceability from XTD Special Steel’s manufacturing facility. Quality control checkpoints are applied at each stage of production — raw material inspection, dimensional control, mechanical and corrosion testing, and final inspection.
Third-party inspection (SGS, BV, or client-nominated bodies) is welcomed prior to shipment upon request.
