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?

The copper clad steel grounding rod features independent monitoring, testing, and communication capabilities. It accommodates different transmission media and protocols for real-time data transmission. It is suitable for general and special environments like humid, saline, alkali, and acidic soils, used in power plants, substations, communication base stations, airports, and petrochemical plants for protective and working grounding.

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

They provide a safe pathway for electrical energy dissipation, ensuring safety during malfunctions. They offer a stable, low-resistance connection for consistency and protect against stray voltage that could damage equipment or cause fires. Made of high-strength steel with 99.9% pure copper coating, they ensure durability, corrosion resistance, and excellent conductivity.

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

Pure copper offers 8 times the conductivity of steel and over 10 times the corrosion resistance, with a lifespan exceeding 40 years. However, it is costly and has lower mechanical strength. Copper plated materials balance performance and cost by using a steel core for strength and a copper layer for conductivity, making them suitable for most engineering scenarios.

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

Copper clad steel rods last over 30 years, pure copper rods over 40 years, and galvanized steel rods 10-15 years. Lifespan depends on material, soil corrosiveness, and environmental factors. Copper clad steel offers high cost-effectiveness, while pure copper is more durable.

Q:What are the customization options available?

Customization options include customization from samples, designs, full customization, minor customization, and flexible customization. The manufacturing process allows for specific requirements regarding dimensions and specifications.
