The Solar Photovoltaic Carport manufactured by Guojian (Tianjin) Steel—a direct factory source—are integrated steel structures designed for both parking and power generation, suitable for industrial and commercial parking areas such as factory complexes, business parks, and charging stations. The main structure is available in materials including Zinc-Aluminum-Magnesium alloy, hot-dip galvanized steel, and aluminum alloy; the complete package includes all necessary components such as uprights, main beams, PV mounting rails, clamps, and fasteners. Featuring a fully bolted, modular design, the system requires no on-site welding and offers various structural configurations, including single-column cantilever and double-column A-frame designs. Structural integrity is verified against project-specific wind and snow load requirements, ensuring a 25-year design lifespan. Services include detailed engineering design and support for orders of any scale (small to large batches), with trade terms available on an EXW or FOB Tianjin Port basis.

Guojian (Tianjin) Steel Co., Ltd. is a specialized manufacturer of Ground‑Mount Solar Mounting System, offering services that range from bulk procurement and project supply to custom fabrication for ground-mounted solar power plants. The company produces three main categories of racking systems—fixed-tilt, adjustable-tilt, and horizontal single-axis tracking—utilizing high-strength, hot-dip galvanized steel (Q235B/Q355B). These systems are suitable for diverse installation environments, including flat terrain, mountainous areas, tidal flats, and agrivoltaic sites. Compatible with various foundation solutions such as helical piles, concrete piles, and ballast blocks, the components are factory-prefabricated for rapid on-site assembly, making them an ideal choice for large-scale photovoltaic projects. We welcome inquiries and partnership opportunities.

Guojian Steel Co., Ltd. is a manufacturer and supplier specializing in Support Bracket Steel Structure. The company handles large-volume orders and offers customization, wholesale, and contract manufacturing services for a wide range of support structure products. With its own in-house production lines, the company manufactures steel support structures that deliver excellent load-bearing performance, making them suitable for equipment support, structural reinforcement, municipal engineering, and auxiliary support systems. We maintain strict control over raw materials and employ advanced welding and finishing processes; anti-corrosion options such as hot-dip galvanizing and painting are available. We also provide detailed engineering design support and ensure stable supply for both domestic and international projects.

Guojian (Tianjin) Steel Co., Ltd. is a direct manufacturer of Triangle Bracket Connector for photovoltaic mounting systems, offering support for bulk project orders, custom hole configurations, and free sample provision. These triangular supports serve as critical reinforcement components connecting mounting posts to purlins; manufactured from high-strength Q355B steel and finished with either hot-dip galvanizing or Zinc-Aluminum-Magnesium coating, they ensure 25 years of outdoor corrosion and rust resistance. Their stable triangular design significantly enhances the mounting system's load-bearing capacity against wind and snow, and they are fully compatible with the company's complete range of C-, Z-, U-, and "Ji"-shaped steel profiles.

Guojian (Tianjin) Steel Co., Ltd. specializes in manufacturing Solar Mounting Pressing Fittings, including mid-standards and end-standards. We offer support for bulk project procurement, custom molds for non-standard module thicknesses, and third-party sample testing. The products are made from 6005-T5 aluminum alloy through an integrated extrusion process. The fixtures feature thickened anti-slip interlocking teeth and EPDM buffer pads, ensuring uniform clamping pressure and effectively preventing micro-cracks in double-layer glass component frames.

Guojian (Tianjin) Steel supplies hot-dip galvanized Round Steel Tube specifically designed for photovoltaic (PV) perimeter fencing and mounting poles. These pipes are manufactured using seamless or straight-seam national standard steel tubing that undergoes a high-temperature, full-immersion galvanizing process. Their smooth, rounded cross-section effectively disperses wind pressure and prevents the accumulation of dust or water, making them ideal for PV site perimeter barriers, surveillance poles, and equipment support columns. We offer custom processing services—including beveling, threading, and drilling—and maintain a comprehensive range of pipe diameters with rapid shipping capabilities. We can also supply complete sets of matching PV steel structural accessories for consolidated delivery. Full material inspection documentation is provided directly from the factory, ensuring compliance with construction acceptance standards for both inland and coastal PV projects, as well as requirements for export.
