AI-Powered supplier vetting

SummaryQingdao Xinguangzheng Steel Structure Co., Ltd. is a limited company offering steel structures, metal structures, new building materials, livestock machinery, and containers. It has stated inventory capacity, quality assurance, customization services, and certifications including ISO9001:2015, ISO45001:2018, and ISO14001. An audit by TÜV Rheinland is listed as valid from January 7, 2026 to January 6, 2027, although the recorded evaluation result is not explained. Key limitations include no valid manufacturing-capacity contract with its related subcontractor, no overseas warehouse, overseas agent or branch, overseas showroom, or offline trade-show participation. The supplier reports no new products in the past year, no ODM, OEM for popular brands, or available SDK. After-sales procedures exist but lack written records, and its approved-supplier list lacks approval signatures or dates. Financial information is represented only by year labels, so credibility cannot be determined.

Supplier typeThe supplier is identified as a limited company whose scope includes metal structure manufacturing and sales, new building materials, livestock machinery, containers, technology services, and foreign contracting projects. Its stated primary product and offered product scope are steel structures, indicating a manufacturer and supplier rather than a service-only intermediary.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications. A TÜV Rheinland audit is recorded with validity from January 7, 2026 through January 6, 2027, but the audit result is recorded as 0 without an explanatory interpretation.

R&D capabilityThe supplier reports no available SDK and no new products during the past year. It also does not provide ODM services, while the listed design options show customization rather than evidence of ongoing product innovation.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also reports quality assurance and a quality-control capability for own-brand products, supporting the existence of customization-related production controls.

Yes, our houses can resist earthquakes, high winds, and snow loads. They are designed to withstand Grade 12 winds and Grade 8 earthquakes.

Q:Do you provide design services?

Yes, we supply design services. Our professional engineers can create safe and economic solutions based on your specific details and requirements.

Q:What are the payment terms?

We accept T/T (30% deposit, balance against ocean bill) or 100% L/C at sight. Other terms include LC, D/P, PayPal, Western Union, and small-amount payments.

Q:How long is the delivery time?
