AI-Powered supplier vetting

SummaryJucai Huixin appears to be a photovoltaic bracket and related metal-structure supplier with broad customization and OEM/ODM capabilities. It reports multiple management and product certifications, including ISO9001, ISO14001, ISO45001, CE and RoHS. Production indicators are substantial, with more than 10 production lines, over 30 quality-control staff, and stated solar-bracket output of 1,000,000 tons. The supplier exports primarily to South America, Southeast Asia/Middle East, Europe and North America, with 71%–90% of sales from exports and self-operated import/export rights. It offers installation, training, repair, maintenance and debugging, but reports no overseas warehouse, showroom, agent or branch. Financial records are referenced for 2022–2024, but no financial results are provided. Innovation evidence is mixed: new products were reportedly developed in the past year and ODM is available, while no SDK is available and total R&D-engineer experience is listed as one year.

Supplier typeThe supplier is presented as a manufacturer and seller focused on photovoltaic mounting systems, including hot-dip galvanized, zinc-aluminum-magnesium coated, aluminum alloy and stainless-steel brackets and accessories. Its registered business scope also covers metal structures, mechanical equipment, construction reinforcement products, wires, cables and hardware, indicating a broader industrial materials scope.

CertificationsThe supplier states that its products and management systems have passed ISO9001, ISO14001 and ISO45001 certifications, as well as CE and RoHS certifications. These explicitly documented certifications support compliance and quality-system capability.

R&D capabilityThe supplier reports that it had new products during the past year and provides ODM services, while also offering multiple forms of design customization. Countervailing evidence includes no available SDK and total R&D-engineer experience listed as one year; therefore, innovation activity is demonstrated but technical depth is not fully established.

Production capacityThe supplier reports more than 10 production lines, annual solar-bracket output of 1,000,000 tons, and 31–40 quality-control staff. It also states average peak- and off-season lead times within 15 working days, providing explicit evidence of substantial production capacity and organized quality control.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization and flexible customization. It also reports both OEM service for well-known brands and ODM service, indicating broad product-development and customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of brand-customer experience. No customer names, project details, order scope or independently verifiable case studies are provided.

Product Q&A

Q:Why choose Zn-Al-Mg over pure zinc coatings?

Mg forms a dense oxide layer to block corrosive ions, extending service life to 25+ years.

Q:Can tubes be welded without damaging the coating?

Yes - pre-coated edges allow welding with minimal spatter; post-weld Mg oxidation self-repairs affected areas.

Q:What is the MOQ?

Standard MOQ: 5 tons (custom sizes available).

Q:How does the factory ensure product quality and compliance?

The company employs advanced testing equipment, including spectrometers (for material composition) and Q-FOG salt spray testers (for corrosion resistance). Products comply with international standards like ISO 9001 and are certified for structural reliability in solar applications.

Q:What are the minimum order requirements and lead times?

The minimum order quantity is 2 tons, with a FOB price range of 2,450-2,950/ton. The factory's monthly production capacity is 5,000 tons, ensuring quick turnaround times. Orders are shipped via the Port of Qingdao, with payment terms like T/T (Telegraphic Transfer) accepted.
