AI-Powered supplier vetting
SummaryNingbo Zhonglian Fastener Manufacture Co., Ltd. is identified as a Chinese limited company operating in Zhejiang and producing construction fasteners, including bolts, nuts, screws, washers, and non-standard fasteners. The supplied information shows ISO9001:2015 certification and also references ISO14001, ISOEN14399CE, and ISOEN15048 approvals. Reported manufacturing resources include automatic cold-forging equipment, hot-forging lines, heat-treatment lines, and an inspection center. The company states that it serves international markets and maintains overseas service institutions, but the evidence does not fully establish current service performance. Production information is inconsistent across the slices regarding establishment date, employee count, plant area, and capacity, so scale should be verified. Customization capability is not explicitly demonstrated. Trade records identify buyers in the United Kingdom and Vietnam, but the number of documented transactions is limited.
Supplier typeThe supplier is classified as a combined business entity and limited company in China, with a stated manufacturing address in Zhejiang. Its products, manufacturing equipment, and description identify it as a fastener manufacturer rather than only a trading intermediary.
CertificationsThe supplier explicitly provides an ISO9001:2015 certificate. Its company description also references ISO9001, ISO14001, ISOEN14399CE, and ISOEN15048 approvals, indicating multiple quality, environmental, and product-related certifications or approvals.
After-Sales capabilityThe supplier states that it provides considerate service and has six domestic direct-sale offices plus overseas regional service institutions in Hungary, Dubai, Malaysia, and the UK. These statements support a service network, although no specific after-sales procedures, response standards, or performance evidence are provided.
Production capacityThe supplier reports nearly 100 automatic cold-forging machines, six hot-forging lines, four imported automatic mesh-belt heat-treatment lines, a professional inspection center, and monthly capacity of up to 2,500 tons. It also lists a broad range of fastener products and international standards, providing explicit evidence of substantial manufacturing capability.
Client casesTrade records associate the supplier with CYNTECH ANCHORS LTD in the UK and CÔNG TY TNHH CST INDUSTRIES VIỆT NAM in Vietnam, covering hex screws, hex nuts, and stainless-steel flat washers. These records demonstrate identifiable international buyer activity, but only a small number of transactions are shown.
