AI-Powered supplier vetting

SummarySINO ZHENG INDUSTRIAL INC. is identified as both a trading company and manufacturer/factory in China, offering magnesium wheels, welding wire, heatsinks, anodes, plates, and related products. It reports ISO 9001 and ISO 14001 certifications, more than 10 production lines, 6–10 R&D engineers, and 6–10 quality-control staff. Export activity is established, with 71%–90% of sales from exports, self-operated import/export rights, exports beginning in 2015, and markets across the Americas, Europe, and Southeast Asia. Product descriptions and company information indicate technical expertise in magnesium materials and welding processes. However, overseas service infrastructure, 3D design, OEM/ODM, after-sales capability, and customization are not sufficiently documented. The audit record identifies BV, but the stated evaluation result is 0, which should be treated cautiously.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory, indicating combined commercial and manufacturing functions. Its listed product portfolio is centered on magnesium products.

CertificationsThe supplier lists ISO 9001 and ISO 14001 management-system certifications. A BV audit is also recorded with validity from September 10, 2025 to September 9, 2026, but the audit evaluation result is stated as 0, so the audit outcome itself does not provide positive assurance.

R&D capabilityThe company describes technological, product, and process innovation, including a one-time extrusion process for 1.2 mm magnesium welding wire and efforts to expand magnesium applications. It also reports 6–10 R&D engineers, but 3D design, new-product development status, ODM, and OEM capabilities are marked unknown.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, and stated output for magnesium welding wire and forged magnesium wheels. It also reports off-peak lead times within 15 working days and peak-season fulfillment of 2–3 months, supporting an established production operation, although the production figures should be interpreted as self-reported.

Client casesTwo records identify the same buyer, CÔNG TY CỔ PHẦN HUY MINH, associated with specified cathodic-protection alloy products imported into Vietnam. These records provide evidence of an associated buyer and product transactions, but they do not establish the scale, duration, performance, or breadth of customer references.

Product Q&A

Q:Why does the price fluctuate, and how can I get the most accurate quote?

Our busbar accessories use high-purity copper as the core material, so the manufacturing cost is directly affected by global copper price fluctuations. The price listed online is for reference only. To ensure you get the best deal, please click "Contact Supplier" to get a real-time quote based on today's raw material market prices and your specific order volume.

Q:Do you support customization or OEM based on our specific drawings?

Yes, we are a professional manufacturer. We can customize the size, material, and even the plating (silver or tin) of the contact pins and sockets according to your technical drawings or original samples. We have our own tooling facility to support rapid prototyping for your specific project needs.

Q:How do I ensure your accessories will fit my existing busbar system?

Compatibility is our top priority. Since different brands (like Siemens or local brands) have different specifications, we highly recommend you provide your technical drawings or a clear photo of your current parts. Our engineering team will verify the dimensions (such as opening size and pin length) to ensure a 100% perfect fit.
