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:How long is the production lead time for a complete steel structure cold storage?

Standard production takes 25-35 days post 3D approval. Steel frames, PU/PIR panels, and units are made concurrently. For urgent projects, inform us of your deadline for expedited scheduling.

Q:Cold rooms have high humidity. How do you prevent the steel framework from rusting?

Steel is treated with heavy-duty hot-dip galvanization or marine-grade epoxy paint. Interior panels have PE/PVDF coatings, isolating steel from moisture, ensuring a 50+ year lifespan.

Q:Are your insulation panels fire-retardant? Will they pass our local building inspections?

Yes. Our PIR panels meet B1/B2 fire-retardant standards, self-extinguish, and comply with local fire safety codes, easing commercial insurance acquisition.

Q:Can the warehouse floor support heavy automated forklifts and multi-tier pallet racking?

Absolutely. Optimized for high-bay racking, we provide thermal-insulated concrete blueprints for floors to support heavy forklifts without freezing or cracking.

Q:If my business grows, can this steel cold storage be expanded in the future?

Yes! Our bolted modular design allows scalability. Unscrew panels and bolt additional bays to extend the warehouse with minimal disruption.
