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 main advantages of copper clad steel grounding rods?

They combine the high conductivity of copper with the high mechanical strength of steel. Features include strong corrosion resistance, a service life of over 30 years, low resistance, and easy installation with rollable threads that do not detach or crack.

Q:What is the copper layer thickness and material purity?

The copper layer thickness is above 0.25 millimeters (typically 0.254mm). The outer layer is coated with high-purity electrolytic copper with a purity of 99.9% or higher.

Q:How deep can the grounding rod penetrate underground?

With a special connection transmission method, the grounding rod can penetrate up to 35 meters underground, meeting low resistance requirements for special occasions.

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

The copper clad steel grounding rod generally has a service life of over 30 years due to its thick copper layer and strong corrosion resistance. Pure copper rods can last over 40 years, while galvanized steel rods last 10-15 years.

Q:Is customization available for this product?

Yes, customization is available. Options include customization from samples, designs, full customization, minor customization, and flexible customization. The color can be customized to Copper.
