AI-Powered supplier vetting
SummaryShandong Dajin Metal Material Co., Ltd. is identified as a Chinese manufacturer/factory based in Shandong, with four production lines, stated production capacities for several steel-bar categories, and export activity across multiple regions. It holds ISO 9001 and OHSAS/OHSMS 18001 certifications and states that it can supply multiple international standards and customized steel products. The supplier reports export activity since 2017 and that exports represent 51%–70% of total sales. Evidence supports production scale, certification, customization, and international trading capability. However, the provided information does not sufficiently establish after-sales service processes, innovation capability, or financial credibility. Trade records show named buyers and shipments involving Brazil and Pakistan, but the limited transaction evidence does not establish broad or sustained customer performance.
Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and operates as Shandong Dajin Metal Material Co., Ltd., a limited company located in Shandong, China. This directly supports its status as a manufacturing supplier rather than only a trading entity.
CertificationsThe supplier reports holding ISO 9001 and OHSAS/OHSMS 18001 management-system certifications. These stated certifications provide explicit evidence of quality-management and occupational health and safety systems, although certificate validity dates and scope are not provided.
Production capacityThe supplier reports four production lines, 11–20 years of total R&D-engineer experience, 11–20 quality-control staff, and substantial stated capacities for steel bar, carbon steel round bar, and cold-drawn steel bar. It also reports ready stock of 1,000–1,500 tons for specified products and exports to multiple global regions, providing explicit evidence of meaningful production and fulfillment capability.
Customization capabilityThe supplier explicitly states that it can provide products to GB, American, German, Japanese, industry, and special steel standards and can offer customized services according to customer requirements. Its listed grades and 5 mm–300 mm size range for certain stocked products further support product configuration flexibility.
Client casesTrade records associate the supplier with named buyers in Brazil and Pakistan and show shipments involving steel-related products through Qingdao, including a recorded transaction count of one for one buyer and two for another. These records provide evidence of actual international customer transactions, but the limited number of documented cases does not establish a broad, long-term, or independently verified customer portfolio.
