Factory Direct Steel Structure for Industrial Warehouse Construction

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.

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. Leveraging a modular design approach, these Frame Steel Structure are engineered for applications such as equipment support, factory partitioning, and auxiliary tooling setups. Moving away from on-site welding and assembly, all components are factory-prefabricated and compatible with various anti-corrosion surface treatments. We offer on-demand customization for both domestic and international projects, providing a comprehensive, one-stop solution—spanning structural analysis and component fabrication to complete system delivery—to meet diverse load-bearing and site-specific requirements.
