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 is the service life of copper clad steel grounding rods?

The service life is generally over 30 years, depending on the copper layer thickness and environmental conditions. Pure copper rods may last over 40 years, while galvanized steel rods last 10-15 years.

Q:How deep can these grounding rods penetrate underground?

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

Q:What are the benefits of pure copper vs. copper plated materials?

Pure copper offers better conductivity (8x steel) and corrosion resistance but is costly with lower mechanical strength. Copper plated materials balance performance and cost, providing steel core strength and approaching pure copper in conductivity and lifespan.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 10 pcs.

Q:What are the payment terms and lead times?

Payment terms include LC, T/T, D/P, PayPal, and Western Union. Lead time is within 15 workdays off-season and one month during peak season.
