AI-Powered supplier vetting

SummaryQINGDAO HUAYUAN STEEL STRUCTURE CO., LTD. is a limited trading company in Qingdao, China, offering steel structure products. It is identified as a professional technical supplier and provides 3D design and multiple customization options. Export activity is substantial, with 90% of total sales reportedly coming from exports and approximately 10 years of export experience. However, the available evidence shows no in-stock capability, overseas warehouse, overseas showroom, overseas agents or branches, and no history of offline trade-show participation. Innovation evidence is weak: no new products were reported in the past year, and the supplier does not provide ODM, popular-brand OEM, or SDK services. Corrective-action and customer-complaint procedures are documented and followed, while quality assurance, raw-material traceability, manufacturing contracts, and some financial and safety information remain unverified. A TUV Rheinland audit is recorded, but the stated audit result is 0 and no certification...

Supplier typeThe supplier is a limited company based in Shinan District, Qingdao, and is classified as a trading company. Its primary and offered product scope is steel structure, while the business scope includes activities requiring approval where applicable.

After-Sales capabilityThe supplier lists equipment installation as an overseas service offering and has documented, followed procedures for corrective and preventive actions and customer complaints. Nevertheless, it has no overseas agents or branches, no overseas warehouse or showroom, and no in-stock service capability, limiting evidence of broad or rapid after-sales support.

R&D capabilityThe supplier is identified as a professional technical supplier and provides 3D software design services. However, it reported no new products in the past year and does not offer ODM, popular-brand OEM, or SDK services, indicating limited demonstrated product innovation.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization, and also provides 3D software design services. These repeated entries provide clear evidence of broad customization capability.

Product Q&A

Q:Direct manufacturer or trading company?

We are a Direct Manufacturer founded in 2000 with top-tier qualifications for steel structures. Avoid markups, work with a certified factory, and partner with a 26+ year leader active in 50+ countries.
