We will furnish you the detailed construction drawing and the construction manual which could help you to erect and install the building step by step. We also could send the engineer to your local to help you if needed.

What is the maintenance requirement?

Finish paint need be done after the frame installed, and do it again after 6-8 months. So the surface will stay more time.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company with permitted import and export activities and a broad business scope that includes metal-material manufacturing, product sales, design, and technical services. It holds ISO 9001 certification and states that it maintains a strict quality management system. ODM and OEM services are available, but no SDK is available. Production-related evidence includes 6–10 quality-control staff, 6–10 years of total R&D engineer experience, and stated order fulfillment within 15 workdays in both peak and off-peak seasons. After-sales procedures exist for corrective and preventive actions and customer complaints, but no written records are maintained. Financial information confirms coverage of 2022–2024 financial-capacity, cash-flow, balance-sheet, and profit-index periods, but provides no performance values, so financial strength cannot be assessed. The supplier cites foreign-company partnerships but provides no identifiable customer cases.

Supplier typeThe supplier is explicitly classified as a trading company and is permitted to conduct goods and technology import and export. Its stated scope also includes manufacturing of metal materials, product sales, design, leasing, and technical services, indicating a broad commercial and operational scope rather than a narrowly defined manufacturing profile.

CertificationsThe supplier explicitly reports holding ISO 9001 certification and states that it maintains a strict quality management system. This provides direct evidence of a formal quality-management certification.

R&D capabilityThe supplier states that it has pursued innovation and reports 6–10 years of total R&D engineer experience. It offers ODM services, but explicitly has no available SDK, so the evidence supports some design and development capability without establishing broader technical innovation strength.

Production capacityThe business scope includes manufacturing of metal materials, and the supplier reports 6–10 quality-control staff. It also states that orders can be fulfilled within 15 workdays during both peak and off-peak seasons, providing direct evidence of an operating production and quality-control capability.

Customization capabilityThe supplier explicitly offers ODM services and describes clothing design among its activities, while also emphasizing continuous improvement and innovation. These statements support the availability of customized design and manufacturing services.
