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:Can your structures withstand extreme hurricanes and heavy snow?

Absolutely. We custom-engineer every building based on your specific local climate data. Whether it's Force 12+ typhoon resistance or extreme snow loads, our designs comply fully with international building codes, including ASTM, Eurocode, and AU/NZS.

Q:Does 'One-Stop Delivery' cover all building components?

Yes. We provide a fully integrated system. Beyond primary steel frames, we supply 100% compatible secondary structures, cladding (PU/Rockwool panels), doors, windows, skylights, and gutter systems. This ensures a perfect fit, eliminates sourcing headaches, and significantly reduces shipping costs through consolidation.

Q:How do you guarantee quality, especially the welding?

Quality is our foundation. We hold the China State Class-One Qualification and are CE/EN1090 certified. Every primary component undergoes Non-Destructive Testing (NDT) before dispatch. Your project is handled by 120+ certified professional welders and 20 senior engineers.

Q:We lack local installers. Is assembly difficult?

Our structures use 100% Bolted Connections, requiring zero on-site welding. We provide detailed 3D installation drawings, step-by-step videos, and clearly numbered components for rapid assembly. For large-scale projects, we can dispatch engineers to your site to guide your team.

Q:How do you prevent damage during long-distance shipping?

We use premium sea-worthy packaging. Heavy beams are secured on custom steel pallets for safe forklift unloading. Insulated panels and fragile parts are wrapped in protective film to prevent scratches and moisture damage during transit.
