Guojian (Tianjin) Steel supplies Back-to-Back Connected Solar Carport, interconnected photovoltaic (PV) carports and welcomes inquiries from new energy general contractors, industrial park property managers, and factory procurement teams. Our in-house developed dual-sided, dual-slope carports feature a robust structure made of thickened hot-dip galvanized C-section steel. They utilize an integrated layout for double-row parking with PV modules installed simultaneously on both sides, maximizing space efficiency. The design includes an integrated drainage and waterproofing system and supports modular, weld-free, rapid installation. With a factory inventory of over 10,000 tons, we offer customizable overall spans tailored to specific site dimensions and parking layouts.

As a primary supplier of municipal steel structures, Guojian Steel Co., Ltd. caters to large-scale procurement, custom engineering projects, and bulk supply of ready-made components, meeting the needs of urban infrastructure and public facility projects. These Municipal Public Steel Structure are fabricated from Q235B/Q355B weathering steel, offering superior corrosion resistance, high wind-load capacity, and design versatility; they support customization of dimensions, aesthetics, and anti-corrosion treatments, featuring factory prefabrication for rapid on-site assembly. Manufactured in strict accordance with national municipal engineering standards, the products come with a one-stop service package covering detailed design, fabrication, quality inspection, and delivery. Widely utilized in urban walkways, landscape structures, bus shelters, pedestrian bridges, and public facilities, they ensure stable supply for large orders and effectively shorten construction timelines, making them an ideal choice for urban public infrastructure projects.

Guojian (Tianjin) Steel is a specialized supplier of Flexible Solar Mounting System in China. The company focuses on prestressed flexible PV mounting systems; its products are manufactured in strict accordance with technical standards, offering excellent corrosion resistance, durability, and compliance with safety load requirements. Designs can be customized based on specific terrain conditions, allowing for flexible adaptation to various complex ground-mounted PV projects. Guojian supports large-volume orders and provides technical drawings, testing certifications, and free project assessments.

Guojian suppliers specialize in manufacturing this Hot‑Rolled Steel Section, which is made from high-quality raw materials through a high-temperature hot rolling process. It has a dense internal structure, high strength, and stable toughness. The product dimensions are precise and comply with various standards (GB, EN, ASTM, JIS), featuring strong load-bearing capacity, good durability, and convenient maintenance.

The Hot‑Dip Galvanized Steel Structure supplied by Guojian Manufacturer adopts the integrated hot-dip galvanizing process, effectively solving common problems in the industry, such as rust caused by rainwater, coastal salt fog corrosion, and frequent rework and maintenance. We use Q235B steel that complies with national standards, ensuring a zinc layer thickness of over 85 micrometers, making the product particularly suitable for photovoltaic car shelters, factory frame structures, pipe supports, and municipal outdoor steel structure projects. We can provide a third-party galvanizing inspection report and offer direct delivery to the customer's location or container export services.

Guojian's China Paint Anti‑Corrosion Coated Steel Structure utilize a physical barrier system, relying on multiple layers of paint to seal out air and rainwater and prevent steel from rusting. Offering flexible production and unrestricted color selection, this method is ideally suited for projects located in standard inland atmospheric environments. It accommodates custom fabrication for everything from small batches of non-standard supports to complete steel frameworks for industrial complexes, balancing aesthetic appeal with project budgets—making it a widely adopted anti-corrosion solution in engineering.
