As a primary supplier of agricultural steel structure, Guojian Steel Co., Ltd. handles large-scale procurement, custom engineering projects, and bulk supply of ready-made components, catering to the needs of agricultural industrial parks and cultivation or livestock farming bases. Constructed from Q235B/Q355B steel, these structures offer exceptional resistance to wind and snow loads as well as superior corrosion resistance. They feature wide spans with unobstructed interiors and support customization regarding dimensions and anti-corrosion treatments; components are prefabricated in the factory for rapid on-site assembly. Designed to meet the specific operational demands of agriculture, we provide a one-stop service covering detailed design, fabrication, and delivery. Widely used for greenhouses, livestock shelters, multi-span structures, and agricultural warehouses, our products ensure stable delivery for large orders and reduce infrastructure investment costs, making them the ideal choice for modern agricultural projects.

As a specialized manufacturer of Cold‑Formed Thin‑Wall Steel sections in China, Guojian (Tianjin) Steel offers high-quality, customized profiles. Our products are manufactured through an integrated roll-forming process using high-strength steel strip and encompass a wide range of cross-sectional shapes, including C-sections, Z-sections, U-sections, and Hat-sections (Omega profiles). Characterized by precise dimensions and excellent mechanical properties, these profiles are widely used in projects such as photovoltaic mounting systems, solar greenhouses, steel-structure industrial plants, and prefabricated buildings. We provide material certification and mechanical test reports, along with product quotations and comprehensive technical documentation for domestic and international clients, serving as a reliable global supplier of cold-formed thin-walled steel.

Guojian (Tianjin) specializes in non-standard prefabricated beam-column steel frameworks.
