AI-Powered supplier vetting

SummaryThe supplier is a combined company engaged in metal structures, hardware products, construction fittings, building materials, doors and windows, and related manufacturing and sales. It reports OEM service for well-known brands, ODM capability, 3D design services, full customization, inventory capacity, and exports accounting for 71%–90% of sales. Its production resources include cutting, shot blasting, welding, assembly, straightening, bending, laser cutting, floor bearing plate, and color steel tile equipment. ISO 9001:2015 and SGS certification are stated, but service procedures, corrective actions, and complaint-handling processes lack written records. The supplier has no available SDK, no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, and only partial financial-year information, so financial credibility cannot be fully assessed.

Supplier typeThe supplier is identified as a combined company. Its stated business scope covers manufacturing and sales of metal structures, hardware products, construction fittings, building decoration materials, doors and windows, and building materials.

CertificationsThe company description explicitly states that the supplier passed ISO 9001:2015 quality management system certification and SGS certification. These statements provide direct evidence of certification holding, although the specific SGS certification scope is not provided.

R&D capabilityThe supplier provides 3D software design services, offers ODM, supports customization from designs and full customization, and reports launching new products during the past year. However, it has no available SDK, so innovation-related capability is positive but not comprehensive.

Production capacityThe supplier lists extensive production equipment and reports inventory capacity, export sales of 71%–90%, and average peak- and off-season lead times within 15 working days. However, it has no valid manufacturing-capacity contract with its related subcontractors, which introduces a documented capacity-management limitation.

Customization capabilityThe supplier explicitly provides customization from customer designs and full customization, supported by 3D software design services and ODM capability. This directly demonstrates broad product and design customization capacity.

Client casesThe supplier states that it participated in the design and construction of the Qingdao Olympic Sailing Center, MEGA Mall, and PURE FLOUR MILL, and has exported products to more than 60 countries, including South Africa, Ghana, Argentina, Australia, New Zealand, Canada, Ethiopia, and Uganda. These reported projects and international markets indicate relevant experience, although independent verification is not provided.

Product Q&A

Q:What is the service life of the portal H-type steel frame?

The service life of the main steel frame can last for 50 years.

Q:How can I assemble the portal H-type steel frame?

All steel components are bolted with no soldering. Walls and roofs are fixed with self-tapping screws or nails. General locksmith teams can assemble it, or we can arrange technicians to guide installation on site.

Q:What are the advantages of the steel frame compared to traditional buildings?

The main advantages are light weight, economy, and low labor intensity. It can be assembled quickly.

Q:How about the cost of prefabricated building?

Compared with concrete buildings, assembly buildings are lighter in quality and more economical. Factory production reduces the labor intensity and time of installation workers at the construction site.

Q:What information is needed for a quote?

Please provide: 1. Dimensions (Length, width, height). 2. Doors and windows details (Dimension, quantity, position). 3. Material for roof and wall. 4. Local climate data (Wind speed, snow load, seismic magnitude). 5. Other requirements or your own drawings.
