Guojian operates its own manufacturing facility in Tianjin, China, serving as the original manufacturer and supplier of H-Rail. Suitable for applications such as automated linear stages, lifting mechanisms, and equipment frames, the rail features a double-web cross-section that ensures uniform load distribution and excellent torsional rigidity. Standard specifications are kept in stock, and services such as custom-length cutting, drilling, and precision machining are available.

Guojian (Tianjin) Steel Co., Ltd. is a specialized supplier of Smart Solar Tracking System, offering one-stop services that include bulk procurement of intelligent tracking systems, wholesale of PV tracking mounting structures, and customization of single-axis horizontal tracking systems. As a direct manufacturer, we produce intelligent tracking systems—including single-axis horizontal, single-axis tilted, and dual-axis models—that are widely used in various photovoltaic power plants. By tracking the sun's angle in real-time, these systems boost power generation by 15%–25% compared to fixed mounting structures. Equipped with intelligent controls and automatic wind-protection leveling functions, our systems ensure stable and reliable operation, making us a trusted procurement partner for PV power plant investors. We welcome inquiries regarding price quotes.

Guojian (Tianjin) Steel Co., Ltd. is a primary manufacturer of Rooftop PV Mounting System, specializing in project procurement, bulk orders for photovoltaic (PV) carports, and steel structure fabrication for parking canopies. We independently manufacture various structural designs—including square-tube, T-shaped, C-shaped, 7-shaped, and connected dual-bay carports—using Q235B hot-dip galvanized steel. These structures feature PV panels on top for power generation and provide overhead shelter for vehicles; they also incorporate built-in drainage channels and designated spaces for EV charging stations. Components are factory-prefabricated and assembled on-site via bolting, making this an ideal solution for the green upgrading of commercial and industrial parking lots. We welcome inquiries and requests for samples.

Guojian Steel Co., Ltd. supplies large-scale floating photovoltaic (PV) mounting systems and welcomes inquiries regarding procurement. This Floating PV Mounting System enables a dual-use model combining floating solar power generation with underwater aquaculture, significantly enhancing water surface utilization and output value per unit area. Featuring easy installation, a simple structure, and flexible operation, the system is compatible with various PV module layouts. It is an eco-friendly, reusable solution that balances power generation and aquaculture yields, making it an ideal choice for "fishery-solar complementary" projects.
