The Industrial Factory Steel Structure supplied by Guojian Manufacturer is a prefabricated and assembled steel frame system. It is designed to select materials and optimize the structure based on different factory loads and site conditions, and reasonably combines Q235B and Q355B national standard hot-rolled steel, taking into account both structural strength and project cost.

Guojian Steel Co., Ltd. specializes in supplying steel mounting systems for Metal Roof Solar Mounting System, offering one-stop procurement and customization services for industrial plants, warehouses, and rooftop photovoltaic installations. Dedicated to the R&D and manufacturing of steel mounting structures, the company focuses on concealed-fix (snap-lock) and standing-seam systems—products characterized by high strength, corrosion and wind resistance, and ease of installation. We provide tailored selection, wholesale availability, and comprehensive project support. Our detailed specifications, performance parameters, installation guidelines, and quality standards help customers select the right solutions efficiently, reduce costs, and ensure the structural safety and long-term stable operation of their roofing systems.

This China Square Tube Solar Carport System, manufactured by Guojian Factory, adopts an enclosed rectangular tube integral frame structure. The main beams, columns, and secondary beams are all made of closed-section pipe materials, which possess stronger bending and compression resistance. The overall structure is stable and does not shake or deform easily, ensuring excellent stability for long-term outdoor use.

Guojian (Tianjin) Steel Ground Dual‑Post Solar Mounting System is designed specifically for ground-mounted solar power plants worldwide. Featuring a stable dual-post structure and a durable anti-corrosion coating, the system offers high load-bearing capacity and adaptability to diverse climatic conditions. Its modular design ensures efficient installation and allows for customization based on site conditions and local meteorological data, making it suitable for various large-scale solar farm projects.

The Ground Single‑Post Solar Mounting System produced by Guojian suppliers features a single column as the main load-bearing component. The entire load-bearing framework consists of columns, crossbeams, diagonal braces, guide rails, pressure blocks, and a complete set of standard fasteners. The product is compatible with two mainstream foundation types: spiral ground anchors and independent concrete foundations. It can be applied to various complex terrains such as flat land, gentle slopes, farmland, and tidal flats.

Guojian is a reliable manufacturer and supplier of Plate Welded Steel Components. This product is a non-standard heavy-duty steel structure product made from medium-thick steel plates, through processes such as CNC cutting, assembly, automatic welding, straightening, non-destructive testing, and precision processing. These components mainly include customized steel structures, such as welded H-beams, welded box columns, welded cross beams, special-shaped welded steel components, equipment bases, steel structure supports, flanges, and large-scale spliced load-bearing components.
