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 characteristics of copper-clad steel grounding rods?

They feature independent monitoring capabilities, digital communication, and database management. They are suitable for various soil conditions including humid, saline, and acidic environments, and are widely used in power plants, substations, and communication base stations.

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

The copper layer thickness is generally above 0.25 millimeters (specifically 0.254mm in standard models). The coating is made of 99.9% pure high-purity electrolytic copper, ensuring excellent conductivity and corrosion resistance.

Q:How does the service life compare to other grounding materials?

Copper-clad steel grounding rods have a service life of over 30 years. This is significantly longer than galvanized steel (10-15 years) and comparable to pure copper rods (over 40 years), offering a balance of durability and cost-effectiveness.

Q:What is the maximum grounding depth achievable?

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

Copper-clad steel balances performance and cost. It provides high mechanical strength through the steel core and reduces costs while approaching pure copper in conductivity and lifespan. Pure copper has better conductivity but is more expensive and has lower mechanical strength.
