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 of copper-clad steel grounding rods?

They feature independent monitoring, support different transmission media, and use digital communication. They are suitable for humid, saline, acidic soils and chemical corrosive environments, widely used in power plants, substations, and communication base stations.

Q:What is the main function of copper-plated grounding rods?

They provide a safe pathway for electrical energy to dissipate underground, ensure a stable grounding reference point, and protect against stray voltage to prevent equipment damage or fires.

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

Copper-clad steel grounding rods generally last over 30 years due to their thick copper layer and corrosion resistance. Pure copper rods last over 40 years, while galvanized steel rods last 10-15 years.

Q:How does pure copper compare to copper-plated materials?

Pure copper has 8 times the conductivity and better corrosion resistance but is costly with lower mechanical strength. Copper-plated materials balance cost and performance by using a steel core for strength and a copper layer for conductivity.

Q:What is the minimum order quantity and lead time?

The minimum order quantity is 10 pcs. The average lead time is one month during peak season and within 15 workdays during the off-season.
