Can the top of the packing box be stepped on?

People can step on the top. We have done an experiment where 20 people could step on the top without any problem.

Will there be any unusual noise when the wind blows on the top of the packing box?

The old process was to lay the skin on a 6-meter surface. The new process is to lay the skin on a 3-meter surface. The advantage is that there is no water accumulation, no abnormal noise, and the top is more solid.

AI-Powered supplier vetting

SummaryThe supplier is a combined company engaged in R&D, manufacturing, processing, sales, and multiple building-related product areas. It reports professional technical supplier status, 3D software design, broad customization options, inventory, overseas warehouse and showroom capabilities, and exports to 35 countries and regions. Its stated scale includes more than 500 employees and annual production capacity of 50,000 packaging-box sets. Quality assurance exists, but material traceability is absent, and inspection, corrective-action, complaint-handling, and supplier-assessment procedures lack written records. No valid manufacturing-capacity contract with related subcontractors is reported. Financial records are identified for 2022–2024, but no performance values are provided. The evidence supports production, customization, and international-service strengths, while certification, financial credibility, innovation through SDK availability, and customer-case validation remain insufficiently evidenced.

Supplier typeThe supplier is identified as a combined company and describes itself as a group integrating R&D, production, processing, and sales. Its stated business scope covers metal structures, containers, building materials, metal products, and related construction services, while it is also identified as a professional technical supplier.

After-Sales capabilityThe supplier states that it provides excellent after-sales service and has inventory, overseas warehouse, and overseas showroom capabilities. However, its complaint-handling and corrective/preventive-action procedures have no written records, which limits verification of execution effectiveness.

R&D capabilityThe supplier reports R&D capability, professional technical supplier status, and 3D software design services, and describes group-level integration of R&D with production. It also explicitly reports no available SDK, so innovation capability is supported in general but not across SDK-based development.

Production capacityThe supplier reports more than 500 employees, annual capacity of 50,000 packaging-box sets, multiple production bases, inventory capability, and peak- and off-season lead times within 15 working days. The absence of a valid manufacturing-capacity contract with related subcontractors is a control weakness, but the stated internal scale and production information support capability.

Customization capabilityThe supplier explicitly offers customization from designs, full customization, minor customization, customization from samples, and flexible customization. It also provides 3D software design services, directly supporting design-led and sample-based customization.

Client casesThe supplier states that its products have been exported to Australia, the Middle East, Asia, Africa, South America, and 35 countries and regions. This demonstrates geographic market experience, but no named customers, project details, order references, or independently verifiable case studies are provided.
