Hot Rolled ASTM A36 Ipn 400 Steel H Beam / Beam Steel I-Beam

A36 China Steel I Section & H Beam Assortment, compliant with Chinese steel size standards and available in Q235, Q345, and A36 grades, constitutes a comprehensive structural steel solution for diverse industrial and construction applications. Encompassing I-beams, H-beams (including IPE series), angle steels, and other iron structural components, this product lineup is engineered to deliver exceptional mechanical performance, dimensional precision, and structural reliability, catering to the rigorous demands of modern iron structure projects.Hot Rolled ASTM A36 IPN 400 Steel H Beams stand out as high-performance structural components, engineered to comply with ASTM standards and tailored to the IPN 400 specification- a critical benchmark for I-section beams in industrial and construction applications. As hot-rolled structural steel members, these beams integrate the superior material properties of ASTM A36 steel with the optimized structural design of IPN 400, delivering exceptional load-bearing capacity, dimensional precision, and reliability for a wide range of heavy-duty and general construction projects.

From a material perspective, the product range features three high-performance steel grades-Q235, Q345, and A36-each tailored to specific load-bearing and environmental requirements. Q235 carbon steel, with a minimum yield strength of 235 MPa, offers excellent weldability and cost-effectiveness, making it ideal for general structural applications. Q345, a low-alloy high-strength steel (yield strength ≥345 MPa), provides enhanced toughness and fatigue resistance, suitable for heavy-duty structures and harsh working conditions. A36, a widely recognized American standard carbon steel (yield strength ≥250 MPa), ensures compatibility with international construction systems while maintaining superior ductility and machinability. All products adhere to strict Chinese steel section size standards, guaranteeing consistent dimensional accuracy across batches, which is critical for seamless assembly and structural stability.From a material standpoint, ASTM A36 steel is a globally recognized carbon structural steel, renowned for its well-balanced mechanical properties. It boasts a minimum yield strength of 250 MPa and a tensile strength range of 400-550 MPa, endowing the IPN 400 beams with robust resistance to static pressures, dynamic loads, and fatigue-key requirements for long-term structural stability. Compliance with ASTM standards ensures rigorous quality control, including strict testing for chemical composition (predominantly iron with controlled carbon, manganese, and silicon content) and mechanical performance, guaranteeing consistency across batches and interoperability with international construction systems. Additionally, ASTM A36 steel exhibits excellent weldability and machinability, facilitating seamless fabrication, on-site assembly, and customization to adapt to specific project designs, thereby enhancing construction efficiency and reducing lead times.

The structural design of the H-beams and I-beams (including IPE series) in this lineup is optimized for maximum load-bearing efficiency. H-beams, characterized by parallel flanges and a rigid central web, excel in resisting bending, shear, and axial forces, making them the preferred choice for building frames, bridge girders, and industrial workshop structures. I-beams (IPE series, a European standard I-section) feature a tapered flange design that balances strength and weight, suitable for floor beams, purlins, and secondary structural components. Angle steels, with their L-shaped cross-section, provide excellent bracing and connection capabilities, complementing H-beams and I-beams in forming stable iron structures. All components undergo precision manufacturing processes, including hot rolling, which refines the steel grain structure, enhances structural integrity, and ensures uniform mechanical properties throughout the section.The hot-rolled manufacturing process and IPN 400 specification are defining features that elevate the performance of these beams. During hot rolling, ASTM A36 steel billets are heated to temperatures exceeding 1000°C, then continuously rolled into the precise IPN 400 cross-sectional profile-characterized by a tapered I-shape with standardized flange width, web thickness, and overall depth (400 mm as per IPN 400 standards). This hot-rolling process refines the steel's grain structure, enhancing its toughness, ductility, and structural integrity compared to cold-formed alternatives. The IPN 400 design optimizes load distribution, allowing the beam to efficiently resist bending, shear, and axial forces while maintaining a favorable strength-to-weight ratio. This structural efficiency minimizes the beam's self-weight without compromising rigidity, contributing to lightweight building designs, reducing foundation loads, and lowering overall construction costs.

Designed for versatility, this comprehensive steel structural product range is widely applicable in commercial buildings, industrial plants, bridges, infrastructure projects, prefabricated constructions, and mechanical equipment frames. Compliance with Chinese steel size standards ensures compatibility with domestic construction codes, while the inclusion of A36 grade facilitates integration into cross-border projects. The inherent durability of Q235, Q345, and A36 steels, combined with optional surface treatments (such as galvanization or painting), provides excellent resistance to corrosion, wear, and environmental degradation, extending the service life of structures. Whether used in primary load-bearing systems or auxiliary structural components, these H-beams, I-beams, angle steels, and related iron structures deliver consistent performance, structural safety, and cost-efficiency, solidifying their position as a cornerstone of modern construction and industrial steel solutions.Designed for versatility and heavy-duty application, Hot Rolled ASTM A36 IPN 400 Steel H Beams serve as core structural elements in industrial warehouses, factory buildings, bridges, infrastructure projects, commercial high-rises, and prefabricated constructions. The IPN 400 specification ensures compatibility with European and global structural design codes, making them suitable for cross-border projects. The hot-rolled surface finish, combined with the inherent durability of ASTM A36 steel, provides good resistance to wear and environmental corrosion; optional protective coatings (such as galvanization or epoxy painting) are available to extend service life in harsh conditions. Whether employed in load-bearing frames, floor systems, bridge girders, or mechanical equipment supports, these beams deliver consistent performance, structural stability, and cost-effectiveness, solidifying their position as a preferred choice in the global construction and industrial structural steel market.
