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 are the characteristics and applications of copper-clad steel grounding rods?

They feature independent monitoring, digital communication, and database management. Suitable for general and special environments like humid, saline, or acidic soils. Used in power plants, substations, airports, railways, and high-rise buildings for lightning and anti-static grounding.

Q:Why are copper plated grounding rods used for lightning protection?

They provide a safe pathway for electrical energy dissipation, ensuring system safety. They offer a stable grounding reference point, prevent stray voltage, and are durable, corrosion-resistant, and cost-effective compared to pure copper.

Q:What are the benefits of pure copper grounding materials compared to copper plated materials?

Pure copper has 8x better conductivity and 10x better corrosion resistance than steel, with a lifespan over 40 years. Copper plated materials balance cost and mechanical strength using a steel core, offering similar conductivity and lifespan but with a thinner copper layer.

Q:What is the service life of the grounding rod?

Copper clad steel lasts over 30 years, pure copper over 40 years, and galvanized steel 10-15 years. Lifespan depends on soil corrosiveness and environmental factors.

Q:What is the average thickness of the copper layer?

The average thickness is greater than or equal to 0.254mm, ensuring strong corrosion resistance and a service life of more than 50 years.
