AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier offering 3D software design and multiple customization options. It operates two production lines and reports capacity for glass railings, aluminum windows and doors, and glass curtain walls, but no quantitative output is provided for glass pool fencing. Quality-related evidence includes stated compliance with GB/T 19001-2000 and several certifications, quality assurance, and raw-material traceability. The supplier has export experience, self-operated import/export rights, and inventory capability. However, several control procedures lack written records, there is no continuous production quantity reconciliation, no outsourcing SOP, and no valid manufacturing contract with an affiliated subcontractor. Financial records are referenced for 2021–2023, but no financial results are provided. Evidence for customer cases, overseas warehouses/showrooms, environmental assessments, and fire-drill capability is insufficient or negative where explicitly...

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier, emphasizes product design and development, and reports a factory location, production lines, and R&D engineers. This supports classification as a manufacturing-oriented technical supplier.

CertificationsThe supplier states that its quality management system accords with GB/T 19001-2000 and that it holds CE, AAMA, BSCI, RoSH, and REACH certifications. These are explicit certification and quality-system claims, although no certificate validity periods or documents are provided.

R&D capabilityThe supplier reports professional R&D capability, 3D software design services, design and product-development focus, and three years of R&D engineer experience. However, it explicitly has no available SDK, so innovation capability is evidenced in design and customization rather than SDK development.

Production capacityThe supplier operates two production lines and reports annual capacity of 200,000 square meters for glass railing, 20,000 square meters for aluminum windows and doors, and 100,000 square meters for glass curtain walls, plus in-stock capability. Control weaknesses include no continuous quantity reconciliation, no outsourcing SOP, and no valid contract with an affiliated subcontractor.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and states that it addresses individual customer wants and needs. This is direct evidence of broad customization capability.

Product Q&A

Q:Do you supply standard sizes or custom products?

Both. We supply standard sizes to overseas distributors and customized products for end-customers, developers, and builders.

Q:Do you provide installation services in Australia?

We provide installation guides and recommend sub-frames for various wall types. We can also send our installation team to the project site if necessary.

Q:What is the packaging like for overseas shipments?

We have successfully exported many windows and doors with no complaints regarding packaging. We can send photos to show the details of our secure packages.

Q:Are there price differences between powder coating and anodizing?

No price difference. Anodized is recommended for houses near salt water for corrosion resistance, while powder coating is better for houses far from salt water.

Q:What hardware brands do you supply?

We supply China top brands, Australia Doric, and others. We recommend Australia Doric for Australian projects for easy replacement, though prices vary by brand and locking system.
