AI-Powered supplier vetting

SummaryQingdao Changdi is a limited company with 22 employees and offers Ground Rod products alongside metal, alloy, mold, mechanical/electrical, and distribution equipment-related activities. It reports manufacturing-related facilities, valid contracts with associated subcontractors, inventory capability, documented service procedures, complaint-handling processes, and OEM service for well-known brands. Its customization capability is broad, covering samples, designs, full customization, minor customization, and flexible customization. However, it has no overseas warehouse or showroom, no available SDK, and only two years of export experience. Certification holdings and customer cases are not evidenced. Reported financial figures are excluded from this assessment for privacy.

Supplier typeThe supplier is identified as a limited company and is not part of a larger company group. Its stated scope includes Ground Rod products and sales or manufacturing activities involving molds, mechanical and electrical equipment, distribution switch control equipment, metals, alloys, and related products.

After-Sales capabilityThe company describes excellent after-sales service as a business guarantee, while its service assessment, corrective and preventive action, and customer complaint processes are described as having written procedures and followed records. This supports a documented service-management capability, although specific service response performance is not provided.

R&D capabilityQingdao Changdi states that research and development is a core focus and that it combines product technology innovation with practicality. It also reports OEM service capability, but no SDK is available, so the evidence supports product R&D claims rather than software-development or SDK capability.

Production capacityThe supplier reports a production line including chamfering, cutting, marking, diameter-changing, threading, and plating equipment, as well as manufacturing activities for molds and distribution switch control equipment. It also reports valid manufacturing contracts with associated subcontractors and inventory capability; however, its employee count is 22 and no production-volume data is provided.

Customization capabilityThe supplier explicitly reports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This directly indicates broad stated design and customization coverage.

Product Q&A

Q:What is the service life of the copper-clad steel grounding rod?

The service life generally exceeds 30 years, with some specifications indicating over 50 years due to the thick copper layer and strong corrosion resistance.

Q:What are the benefits of copper-clad steel compared to pure copper?

Copper-clad steel balances performance and cost by providing a copper layer on a steel core, offering good conductivity and corrosion resistance at a lower cost than pure copper.

Q:How is the connection made for the grounding rod?

Connections are made using dedicated connecting pipes or hot melt welding (exothermic welding) to ensure firm, stable, and low-resistance joints.

Q:What certifications does the product have?

The product has passed ISO9001, CE, ISO 45001, and ISO 14001 system certifications.

Q:Is customization available for this product?

Yes, customization is available including color, manufacturing process, and specific copper layer thickness, with samples offered on demand.
