PV Mounting
Ground, rooftop, carport, fishery-solar and tracking PV mounting structures from Jinghai, Tianjin — manufacturing and export on record, ISO 9001/14001/45001 to 2028 and 14 patents; seven insured staff against much larger stated figures is the open check.
Solar structures first, brackets alongside.
Hot-Dip Galvanized Ground Mounts
Fixed-tilt ground structures for utility and commercial solar plants, in C- and U-section steel galvanized after fabrication. Specify module size and layout, wind and snow loads, soil and foundation type, and the galvanizing thickness you require (for example to ISO 1461 or ASTM A123).
Zinc-Aluminium-Magnesium Structures
Mounts roll-formed from Zn-Al-Mg coated steel, which is cut after coating and relies on the coating’s self-healing at edges. Ask for the coating weight (g/m²), the steel grade and salt-spray or corrosion-category data for your site.
Tracking & Flexible Systems
Single-axis tracking mounts and cable-suspended flexible structures for long spans over uneven ground, ponds or farmland are listed on the company website. These are engineered systems: ask for structural calculations, wind-tunnel or field data and who supplies the drive and controller.
Fishery-Solar & Floating Mounts
Pile-based structures for fish-pond and water-surface plants. Corrosion and pile design dominate here; confirm coating system, pile embedment and whether the design has been stamped by a structural engineer for your jurisdiction.
Carports & Commercial Rooftop
Solar carport frames and commercial rooftop racking. Carports carry both module and vehicle-impact considerations; ask for load tables and anchor details.
Seismic & Pipe-Gallery Brackets
Seismic support brackets, pipe-gallery and suspension brackets for building services and utility tunnels are in the registered scope — a second line using the same cold-formed steel.
What the registry confirms, and what stays open.
A PV-Mounting Manufacturer by Scope
The registered scope names solar PV mounting processing and manufacturing, pipe-gallery, seismic and suspension bracket manufacturing and steel-pipe processing, with an industry code for ferrous metal rolling. Registered capital is RMB 38.88 million with RMB 20.9 million paid in. A pollutant-discharge permit runs to 2030 and three special-equipment licences were issued in 2025.
Export Registration and Management Systems
Import and export are in scope and the company is registered with Jinghai Customs as an import/export consignor-consignee. ISO 9001, ISO 14001 and ISO 45001 certificates issued in November 2025 run to November 2028. It holds an A tax-credit rating for 2025.
High-Tech Status and Patents
National High-Tech Enterprise certificate GR202312000655 runs to 2026-11-06, and 14 patents are recorded in the company’s name. Ask which patents cover the structures you plan to buy; Chinese patents protect in China only.
Seven Insured Staff
The record shows seven social-insurance contributors, while the application states 50–100 staff, a solar-industry directory lists 200, and the website describes a 20,000 m² production base. Steel-fabrication belts commonly use contract labour, but the gap is large; ask for a live walkthrough of roll-forming, punching and galvanizing, and who operates them.
Two Addresses in Jinghai
The application gives a plant location in Daqiuzhuang and the company website gives an industrial area in Caigongzhuang, both in Jinghai District. Confirm which site will produce and inspect your order, and whether galvanizing is done in-house or by a nearby plant.
Court Record: Collecting Payments
Eight court hearings on record are sales-contract cases the company brought as plaintiff against buyers, typically for unpaid invoices. No penalty, enforcement or dishonesty record appears against it.
What was checked — and what the check found.
The stamp rests on a registration check that lines up with the product: the credit code passes the national check-digit rule, the company is active with a PV-mounting manufacturing scope and substantial paid-in capital, customs-registered, ISO 9001, 14001 and 45001 certified to 2028, a High-Tech Enterprise with 14 patents, holding a discharge permit and an A tax rating, with court activity limited to claims it brought. What stays open: seven insured staff against far larger stated workforces and a 20,000 m² base; two different plant addresses; and structural or EU product documentation, which was not provided. What would close it: a live walkthrough of the line, the address for your order, and structural calculations and coating test reports for your project.
A Tianjin mounting-structure maker, read off the record.
Tianjin Shenglongze New Energy Technology Co., Ltd. (天津市盛隆泽新能源科技有限公司) was registered on 2017-08-22 in Jinghai District, Tianjin — the steel-pipe and cold-formed steel belt around Daqiuzhuang. It makes solar mounting structures: hot-dip galvanized and zinc-aluminium-magnesium ground mounts, tracking and flexible cable systems, fishery-solar and carport structures, commercial rooftop racking, and seismic and pipe-gallery brackets.
Its website presents a 20,000 m² production base, quick production cycles, management-system certification and a range covering utility, commercial and agrivoltaic projects; a solar-industry directory lists it with 200 staff. The Chinese record confirms the core: manufacturing scope, export registration, ISO 9001/14001/45001 valid to 2028, High-Tech Enterprise status, 14 patents and a discharge permit to 2030.
The number that does not fit is headcount: seven insured staff. Buyers placing structural orders should see the roll-forming and galvanizing operation, confirm the producing address, and require project-specific structural calculations and coating data. Contact routes through ChinaMakersHub; direct details are exchanged after first inquiry.

Frequently Asked Questions
What does Shenglongze make?
Solar PV mounting structures — hot-dip galvanized and zinc-aluminium-magnesium ground mounts, single-axis tracking and flexible cable systems, fishery-solar and carport structures, and commercial rooftop racking — plus seismic, pipe-gallery and suspension brackets, in Jinghai, Tianjin.
Is it a manufacturer?
The registered scope names PV-mounting and bracket manufacturing and steel-pipe processing, the industry code is ferrous metal rolling, and it holds a discharge permit and special-equipment licences. Only seven staff are insured, far below the 50–100 stated and the 200 listed in an industry directory, so a live walkthrough of the production line is recommended.
Can it export directly?
Yes. Import and export are in scope and it is registered with Jinghai Customs as an import/export consignor-consignee.
Which certificates does it hold?
ISO 9001, ISO 14001 and ISO 45001, issued 2025-11-19 and valid to 2028-11-18; National High-Tech Enterprise to 2026-11-06; a pollutant-discharge permit to 2030-09-15. The website also mentions EU certification; no CE or EN 1090 document was provided.
Hot-dip galvanized or Zn-Al-Mg — which should I choose?
Hot-dip galvanizing after fabrication gives a thick coating on all surfaces including cut edges and holes, and suits harsh or coastal sites. Zn-Al-Mg pre-coated steel is lighter and cheaper to process and self-protects cut edges through its coating chemistry, but with a thinner coating. Choose by corrosion category and design life, and specify coating weight or thickness on the order.
What should I ask for on a structural order?
Project-specific structural calculations to your local code, material certificates for the steel grade, coating thickness or weight test records, pile pull-out test plans for ground mounts, and a factory acceptance and loading inspection. For the EU, ask whether steel components are produced under EN 1090 factory production control.
What are the MOQ and lead times?
The application states an MOQ of 25 units, sampling in 3–7 days and production in 25–30 days — figures matching the application form’s own examples — without defining a unit. Solar structures are quoted per project, by MW or tonnage; get lead time per project in writing.
What are the court cases about?
Eight hearings on record are sales-contract disputes the company brought as plaintiff against buyers, which in this industry usually means pursuing unpaid invoices. No penalty, enforcement or dishonesty record appears against the company.
What did the ChinaMakersHub check find?
