AI-Powered supplier vetting

SummaryCHANGZHOU DINGANG METAL MATERIAL CO., LTD. is identified as a China-based manufacturer/factory and limited company in Jiangsu, while another record classifies the associated business as a trading company. The supplier reports six production lines, 11–20 quality-control staff, and substantial stated annual output across pre-painted and coated aluminum products. It holds ISO 14001, ISO 9001, and ISO 20000 certifications, and reports 21–30 years of combined R&D engineer experience. Its stated capabilities include reproducing stone, marble, wood, terracotta, concrete, and rusted-copper finishes, with over 500 major projects completed worldwide. However, the provided records offer limited direct evidence regarding after-sales service and financial credibility. Trade records show several transactions involving aluminum products, but the available transaction history is limited.

Supplier typeThe supplier is explicitly described as a Manufacturer/Factory and a limited company based in Jiangsu, China. A separate record classifies the associated company activity as wholesale and retail and identifies the business as a trading company, indicating mixed business classifications across the provided records.

CertificationsThe supplier reports ISO 14001, ISO 9001, and ISO 20000 management-system certifications. These are explicit certification records and support the presence of formal environmental, quality, and information-technology management systems.

R&D capabilityThe supplier reports 21–30 years of total R&D engineer experience and the ability to reproduce natural finishes including stone, marble, wood, terracotta, concrete, and rusted copper on aluminum. These statements provide explicit evidence of product-development and surface-coating capability.

Production capacityThe supplier reports six production lines, 11–20 quality-control staff, and annual output including 300,000 tons of pre-painted aluminum coil, 60,000 tons of AA3105 coated aluminum coil, 45,000 tons of AA3003 prepainted aluminum coil, 30,000 tons of wood-color coated aluminum coil, and 5,500 tons of AA5052 alloy coated aluminum. The factory location is stated as being in Lianshui, Huai'an, Jiangsu.

Customization capabilityThe product portfolio covers multiple coated aluminum coil and sheet types, including channel-letter, trim, PVDF-painted, wood-color, and alloy-specific products. The stated ability to reproduce several natural-material appearances and complete difficult fabrication and coating projects indicates customization capability for finishes and project applications.

Client casesThe supplier claims to have completed over 500 major projects worldwide, and trade records identify buyer-linked transactions involving steel sheet and anodized mirror aluminum sheet coil with buyers in the available records. The evidence supports international project and transaction experience, although the records do not provide detailed project names, scopes, dates, or performance evaluations.
