AI-Powered supplier vetting

SummaryThe supplier operates across steel, mechanical equipment and components, construction materials, and related trading activities, with stated steel R&D, production, processing, sales, and service coverage. 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. No management-system certifications, overseas showroom, overseas agents or branches, or offline trade-show participation are reported. Financial information for 2023 and 2024 shows zero reported operating revenue, operating cost, gross profit, and operating profit, which creates significant uncertainty regarding current financial activity. Production information includes 1,000 space capsules and a stated annual output range, while finished products are checked by packing staff. Named customer resources include major Chinese aerospace, railway, construction, automotive, and real-estate organizations, although the nature...

CertificationsThe supplier reports no certifications for management systems. This is explicit evidence that no such certification is held or reported in the supplied information.

Financial creditThe supplied financial records report zero operating revenue, operating cost, gross profit and operating profit for 2024, and zero operating revenue for 2023. These figures do not demonstrate positive operating performance and create a material concern about financial credibility.

R&D capabilityThe supplier states that it is not a professional technical supplier, provides no 3D software design services, and has no available SDK. Its company description does mention steel R&D, but only one year of R&D engineer experience is reported, providing limited support for strong innovation capability.

Production capacityThe supplier describes steel production and processing and reports an annual production output range together with 1,000 space capsules. It also reports one-month lead times in both off-peak and peak seasons, although finished-product inspection is assigned to packing staff and detailed production resources are not provided.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, full customization, customization from designs, and customization from samples. These stated options directly support broad customization capability, despite the absence of 3D software design services.

Client casesThe supplier identifies customer resources including China aerospace, China Railway entities, Sinotruk, construction companies, Shandong Expressway, Vanke Real Estate and BYD. These named organizations support the existence of claimed customer relationships, but the supplied information does not specify products, order scope, project outcomes or dates.

Product Q&A

Q:How does the double expansion design work?

Both sides of the container extend outward simultaneously, instantly expanding the internal space, especially the central area, to create a spacious living environment.

Q:Is the container safe to drive after retraction?

Yes, when retracted, the width returns to standard road-compliant dimensions (around 2.5 meters). However, you must ensure both cabins are fully retracted and locked before driving.

Q:What materials are used for the structure?

The structure is made of galvanized steel pipe, providing earthquake resistance, durability, and waterproof and anti-corrosion properties.

Q:Can the container be customized?

Yes, we offer flexible customization options including minor customization, full customization, and customization from designs or samples via OEM and ODM services.

Q:How is the expansion mechanism controlled?

The expansion is typically driven by an electric motor controlled by dedicated buttons, allowing for simple one-click operation to open or close the cabin.
