Huiju
Jinda PV Mounting
Solar mounting structures from a Tianjin trading company that designs and inspects in-house and sources from the Daqiuzhuang steel belt — a trade-only scope stated up front; the producing mill is the first thing to confirm.
Structures sourced, designed and inspected.
Ground-Mount PV Structures
Fixed-tilt steel structures for utility and commercial ground-mounted plants. As a supplier rather than a mill, the value it adds is design, sourcing and inspection; ask for the structural calculation, steel grade, section sizes and galvanizing specification for your layout.
Rooftop & Carport Racking
Commercial rooftop and carport structures. Send roof type, loads and module data; confirm attachment method and who stamps the design for your jurisdiction.
Steel Sections & Purlins
C- and Z-section purlins, rails and pipes for mounting systems, supplied from partner steel producers. Specify coating (hot-dip galvanized or Zn-Al-Mg), thickness and length tolerance.
Brackets, Clamps & Fasteners
Mid and end clamps, connectors, anchors and fasteners that complete a mounting kit. Ask for stainless or coated-steel grades and torque specifications.
Metal Guardrails & Pipes
The company’s registered trademarks cover metal brackets, pipes, guardrails and mounting frames for solar panels, which suggests a wider steel-products range from the same sources.
Design & Inspection Service
Recruitment on record includes PV structural engineers, steel detailing engineers and a quality inspector stationed in Daqiuzhuang. Ask for a design package and a third-party or in-house inspection report with each shipment.
What the registry confirms, and what stays open.
A Trading Company by Its Registered Scope
The registered scope is trade: goods and technology import/export, import/export agency, sale of metal materials, PV equipment and components, metal structures and construction metal fittings, plus road freight transport. There is no manufacturing, production or processing clause, the industry code is wholesale, and the registered address is a sixth-floor unit in an R&D office building. The producing factory is not this company.
Design and QC In-House, Production Outsourced
Job postings seen in September 2026 were for PV-mounting structural engineers, steel detailing engineers, foreign-trade sales staff and a PV-mounting quality inspector based in Daqiuzhuang, a major steel-products town in Jinghai, Tianjin. That pattern points to a supplier that designs and inspects while partner mills fabricate. Ask for the mills’ names and a visit.
Management Systems and Its Own Marks
ISO 9001, ISO 14001 and ISO 45001 certificates issued on 2025-08-26 run to 2028-08-25. Trademarks 汇聚金达 and GATHERINGJINDA are filed in class 6 covering metal brackets, pipes, guardrails and metal mounting frames for solar panels. Management-system certificates describe the company’s processes, not the partner mills’ production.
Export in Scope, No Customs Record
Import and export are in scope, but no customs registration appears on the record. Ask whether the company declares exports itself or through an agent, and which entity appears on the commercial invoice and bill of lading.
Young, Thinly Capitalised, No Insured Staff
The company was registered on 2025-02-25 with RMB 5 million registered capital held by one individual; another registry source showed about RMB 1 million paid in. No social-insurance contributors appear, against 50–100 stated. It is a VAT general taxpayer.
A Penalty to Ask About
The registry read on 2026-09-10 shows no adverse record. A different commercial registry source consulted on 2026-09-08 listed one administrative penalty without details. Ask the company for the decision and whether it has been closed.
What was checked — and what the check found.
The stamp is a registration check, not a factory check. The credit code passes the national check-digit rule, the company is active with import/export and PV-structure sales in scope, holds ISO 9001, 14001 and 45001 to 2028 and class 6 trademarks for solar mounting frames, and its recruitment shows structural design and a quality inspector at the Daqiuzhuang steel base. But the scope has no manufacturing clause, the address is an office unit, no staff are insured, no customs registration appears, and another registry source listed an administrative penalty. What would close it: the producing mills’ names and a visit, who holds EN 1090 or UL 2703 for the structures, the penalty decision, and the exporter of record.
A PV-structure trader, read off the record.
Huiju Jinda (Tianjin) International Trade Co., Ltd. (汇聚金达（天津）国际贸易有限公司) was registered on 2025-02-25 in the Huayuan industrial area of Tianjin Binhai Hi-Tech Zone. It supplies solar PV mounting structures — ground, rooftop and carport systems, steel sections, clamps and fasteners — to overseas buyers, with North America and Western Europe named as target markets.
It is a trading company, and says so in its registration: a wholesale scope with import/export and no manufacturing clause, at an office address. What distinguishes it from a pure broker is the team it has been hiring — PV structural and steel detailing engineers, and a quality inspector stationed in Daqiuzhuang, where much of north China’s steel pipe and section production is based — and its own trademarks covering solar mounting frames.
For buyers, the practical model is design, sourcing and inspection by this company, fabrication by partner mills. That can work well, provided you know which mill, who holds the structural and CE or UL documentation, and who exports. Contact routes through ChinaMakersHub; direct details are exchanged after first inquiry.

Frequently Asked Questions
What does Huiju Jinda supply?
Solar PV mounting structures — ground, rooftop and carport systems — plus steel sections, purlins, clamps, fasteners, pipes and guardrails, designed and inspected by the company and sourced from partner steel producers.
Is it a manufacturer?
No. Its registered scope is trade and import/export with no manufacturing clause, its industry code is wholesale and its address is an office unit. Its recruitment of structural engineers and a quality inspector in Daqiuzhuang indicates design and QC in-house with fabrication by partner mills.
Can it export directly?
Import and export are in its scope, but no customs registration appears on the record. Ask whether it declares exports itself or through an agent.
Who holds the structural certification?
Not established. ISO 9001, 14001 and 45001 cover the trading company’s own processes. EN 1090 for the EU or UL 2703 for the US would normally be held by the fabricator or system owner; ask for the certificate and check the holder’s name.
What is the administrative penalty?
A commercial registry source consulted on 2026-09-08 listed one administrative penalty without details; the source read on 2026-09-10 shows none. Ask the company for the penalty decision and closure.
What are the MOQ and lead times?
The application states an MOQ of 25 with no unit, sampling in 3–7 days and production in 25–30 days — figures identical to the application form’s own examples. Solar structures are quoted per project by MW or tonnage.
What did the ChinaMakersHub check find?
Run on 2026-09-10 against Chinese enterprise records: active, registered 2025-02-25, RMB 5 million registered capital, one individual shareholder; trade, import/export and PV and metal products sales in scope, no manufacturing clause; office-building address; ISO 9001/14001/45001 to 2028; class 6 trademarks for solar mounting frames; VAT general taxpayer. Stated as found: zero insured staff, no customs registration, producing mills not named, and a penalty listed on another registry source.
