AI-Powered supplier vetting

SummaryZibo Luzhong Refractory Co., Ltd. is identified as a Chinese manufacturer of refractory materials, operating from a 32,000 m² plant in Zibo, Shandong. The supplier reports 7 production lines, 21–30 quality-control staff, annual refractory output of 120,000 tons, and 186 employees. It holds ISO9001:2008, ISO14001:2004, and OHSAS18001:2007 certifications. The company offers refractory bricks and castables, serves domestic, European, and North American markets, and reports export activity since 2002. Its production scale and management certifications are supported by the provided data. However, evidence is insufficient to assess after-sales service, customization capability, and broader customer-case performance. Innovation claims are present but limited to stated product descriptions.

Supplier typeThe supplier is explicitly classified as a factory and manufacturer, with the legal name Zibo Luzhong Refractory Co., Ltd. and a limited-company structure in China.

CertificationsThe supplier reports ISO9001:2008, ISO14001:2004, and OHSAS18001:2007 certificates, covering quality, environmental, and occupational health and safety management systems.

R&D capabilityThe supplier describes an energy-saving brick and an LTC anti-spalling brick as an invention claimed to be worldwide-first, and identifies specialized refractory products for cement kilns. These statements support some product innovation, although no patents, R&D investment, or validation data are provided.

Production capacityThe supplier reports a 32,000 m² manufacturing plant, 7 production lines, 21–30 quality-control staff, 186 total employees, and refractory output of 120,000 tons. A separate company overview states total production capacity of 200,000 tons per year for the group; together, the data indicate substantial production capability, though the two output figures refer to different scopes.
