AI-Powered supplier vetting

SummaryShandong Hongtian Heavy Industries Co., Ltd. is a China-based combined company established in 2009, engaged in manufacturing, sales, and installation of multiple steel-structure products, including towers, photovoltaic brackets, buildings, and container houses. It reports six production lines, 105 employees, stated production volumes across several product categories, and export markets in South America, Africa, Southeast Asia, and the Middle East. The supplier states that it holds ISO 9001 and ISO 14001 certificates and maintains documented procedures for quality assurance, traceability, corrective actions, and customer complaints. It offers ODM and OEM services, but has no SDK, overseas warehouse, overseas showroom, overseas agent or branch, or offline trade-show participation. Manufacturing-capacity contracting with related subcontractors, in-stock service, and overseas-service coverage are explicitly absent. Customer references are limited to general export and brand-service claims without named cases.

Supplier typeThe supplier is identified as a combined limited company based in Weifang, Shandong, China. Its stated business includes manufacturing, sales, and installation of steel towers, photovoltaic brackets, transformer-substation frames, wind-power towers, and broader steel structures, indicating a manufacturer-integrator rather than a purely trading entity.

CertificationsThe company description explicitly states that the supplier has obtained ISO 9001 and ISO 14001 certificates. The slices do not provide certificate numbers, issuing bodies, or validity dates, but they do provide explicit evidence of certification holding.

R&D capabilityThe supplier provides ODM services, demonstrating stated original-design manufacturing capability. However, it explicitly has no available SDK, and the slices contain no detailed evidence about dedicated R&D resources, patents, laboratories, or product-development performance.

Production capacityThe supplier reports six production lines and quantified output for steel-structure bridges, car showrooms, warehouses, buildings, and container houses. It also has broad manufacturing and installation scope, but it explicitly lacks a valid manufacturing-capacity contract with related subcontractors and has no in-stock capacity, so production scale is evidenced while some capacity-management support is absent.

Customization capabilityThe supplier explicitly offers ODM services and OEM services for popular brands, while its scope covers design, production, sales, and installation of several steel-structure products. These statements support the existence of customization and project-specific manufacturing capability.
