AI-Powered supplier vetting

SummaryThe supplier operates across steel-related research, production, processing, sales, services, equipment, mechanical components, construction materials, and other products. It reports flexible, minor, full, design-based, and sample-based customization, but does not provide 3D software design services and is not identified as a professional technical supplier. Its finished products are checked by packing staff. No management-system certification, overseas showroom, overseas agent or branch, overseas service coverage, or offline trade-show participation is reported. Production information includes 1,000 space capsules and a stated one-month lead time in both off-peak and peak seasons, while the provided financial figures are zero and indicate limited financial evidence. Customer references include major domestic enterprises and construction-related organizations.

Supplier typeThe supplier describes its business as covering steel research and development, production, processing, sales, and service, while its registered scope also includes equipment, mechanical parts, metals, construction materials, supply-chain services, and import/export activities. This supports classification as a diversified industrial and steel-related supplier rather than a narrowly specialized technical supplier.

CertificationsThe supplier’s certification of management systems is explicitly listed as “NIL.” No certification evidence is provided, so the supplier does not demonstrate certification compliance in the available information.

Financial creditThe provided financial records for 2024 show zero operating revenue, operating cost, gross profit, and operating profit, and the prior two-year revenue is also shown as zero. These figures provide no positive evidence of operating financial strength and raise a material credibility concern, although the context does not explain whether the data is incomplete or represents actual performance.

R&D capabilityThe supplier is explicitly not a professional technical supplier, does not provide 3D software design services, and has no available SDK. Although its business description mentions steel research and development and it reports one year of R&D engineer experience, the available evidence does not demonstrate strong innovation infrastructure.

Production capacityThe supplier reports steel-related production and processing activities, broad mechanical and construction-material product coverage, an annual production-output entry of 1,000 space capsules, and one-month lead times in both seasons. These details support the existence of production-related capability, but the evidence is limited and does not fully establish scale across its broad business scope.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, full customization, customization from designs, and customization from samples. This is direct evidence of broad customization options, despite the absence of 3D software design services.

Client casesThe supplier identifies customer or business relationships involving China Aerospace, China Railway entities, Sinotruk, China State Construction-related organizations, Shandong Expressway, Zhongnan Construction, Vanke Real Estate, and BYD. It also reports long-term cooperation with multiple domestic steel mills, providing explicit evidence of notable domestic customer and partner references.

Product Q&A

Q:How does the double expansion design improve living space?

Both sides extend outward simultaneously, instantly expanding the internal space, especially the central area, creating a spacious apartment-like feel with better separation of functional zones.

Q:Is the container house safe to drive after expansion?

No. The vehicle must only be driven after the expansion cabin has been fully retracted and locked. This is the most critical safety step before any movement.

Q:What are the dimensions when the house is retracted?

When retracted, the width returns to the standard size compliant with road regulations, usually around 2.5 meters, facilitating driving and turning.

Q:What materials are used for the structure and sealing?

The structure uses galvanized steel pipe for durability. Sealing relies on multiple waterproof and dust-proof strips (rubber or brush-type) between the cabin and main body.

Q:Can the product be customized?

Yes, flexible customization is available including minor customization, full customization, customization from designs, and customization from samples.
