AI-Powered supplier vetting
SummaryGuangzhou New Zhonglian Building Materials Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory. It offers steel structures, building materials, prefab and container houses, and related products. The supplier reports 13 years as an audited Alibaba Gold Supplier, ISO 9000 and ISO 9001 certifications, six to ten quality-control staff, two production lines, broad export coverage, and a typical off-peak lead time within 15 working days. Its business scope includes engineering construction, materials procurement, whole-house customization, soft furnishing, and after-sales service. However, the provided information does not verify detailed production ownership, financial strength, R&D deliverables, OEM/ODM services, raw-material traceability, or specific customer projects. The SGS audit record shown expired on 2025-08-22, and its evaluation result is recorded as 0 without an explanatory interpretation.
Supplier typeThe supplier is registered in Guangzhou, China, as a limited company, while its business classification identifies it as a trading company, manufacturer/factory, and group corporation. The available information therefore supports a mixed trading-and-manufacturing profile rather than a purely manufacturing identity.
CertificationsThe supplier reports ISO 9000 and ISO 9001 management-system certifications, and an SGS audit was conducted beginning 2024-08-23. However, the SGS record expired on 2025-08-22, so the available evidence does not establish current SGS validity.
After-Sales capabilityThe company description explicitly includes after-sales service for customers. Nevertheless, the slices provide no details on service staffing, response times, warranty procedures, spare parts, or overseas service arrangements; overseas warehouse and showroom capabilities are marked unknown.
Production capacityThe supplier reports two production lines, six to ten quality-control staff, exports to multiple global regions, and an off-peak lead time within 15 working days. Its profile combines manufacturing and trading roles, but the slices do not clarify owned-factory capacity, production volume by product, or raw-material traceability.
Customization capabilityThe company explicitly offers whole-house customization and supplies product categories including steel structure buildings, prefab houses, capsule houses, and container houses. This supports customization capability at the project or product-solution level, although specific design resources, customization limits, and execution processes are not provided.
