Corporate Profile & Development of Guojian (Tianjin) Steel Co., Ltd.
Guojian (Tianjin) Steel Co., Ltd. was founded in November 2020, with a registered capital of RMB 30 million, located in Daqiuzhuang, Jinghai District, Tianjin — a well-known steel manufacturing base in North China with complete industrial supporting chains and convenient land, railway and sea transportation access to Tianjin Port.
At the initial stage, we focused on steel profile processing and steel structure manufacturing, supplying standard metal profiles for construction and new energy industries. Relying on local superior raw material supply, we built stable production lines for C-channels, U-channels and rectangular tubes, laying a solid foundation for our subsequent new energy business layout.
From 2022 to 2024, we accelerated transformation into the photovoltaic new energy sector, independently launched complete production lines for photovoltaic mounting systems, introduced automated punching, cutting and hot-dip galvanizing processes, and formed a full industrial chain covering R&D, production, surface anti-corrosion treatment and supporting accessories. Our annual output capacity reached 200,000 tons, and we were recognized as one of China’s Top 20 PV Enterprises by virtue of stable product quality and large-scale delivery capacity.
Since 2025, we have expanded our global business layout, obtained international certifications including TUV, SGS and UL, launched customized solar carport and heavy-duty steel structure solutions, and carried out import & export business to serve photovoltaic and construction projects across Southeast Asia, Europe, the Middle East and other overseas markets. Up to now, we have formed an integrated operation system combining steel deep processing, new energy equipment manufacturing and international trade.
We integrate R&D, production and sales, with our core product matrix covering photovoltaic supporting systems and engineering steel structures as below:
Our flagship product series includes ground-mounted PV brackets, rooftop PV brackets, tracking brackets and zinc-aluminum-magnesium / hot-dip galvanized steel brackets. All products pass strict wind and snow load tests, with a 25-year anti-corrosion service life, applicable to utility-scale power stations, industrial and commercial rooftops and distributed PV projects worldwide.
We provide one-stop matching components for mounting systems, including C/Z/U steel profiles, screw anchors, mid/end clamps, stainless steel fasteners, aluminum rails and all custom stamped metal parts, supporting flexible matching for various PV module sizes and installation scenarios.
Customized dual-function solar carport steel structures, integrating vehicle shading and power generation. We supply waterproof carport frames, single/double-row parking canopy systems, heavy load-bearing steel frames suitable for corporate parks, commercial plazas and public parking lots, complying with international structural safety standards EN 1991 and ASCE 7.
We manufacture various standard and customized steel structural products: rectangular & square steel tubes, workshop steel frames, metal trusses, construction prefabricated steel components and galvanized metal profiles. Widely used in factory buildings, warehouses, municipal engineering and new energy supporting infrastructure.
Equipped with 8 C-channel production lines, 2 sigma steel lines, laser cutting and automatic punching equipment, we implement full-process quality inspection from raw material incoming to finished product delivery. We maintain long-term cooperation with professional galvanizing factories to control uniform zinc coating thickness, ensuring stable corrosion resistance of all steel products. Our professional technical team can provide customized structural design, load calculation and one-stop procurement solutions for global PV and construction clients, supporting flexible MOQ and on-time bulk shipment.
