Premium Low Carbon Steel Grades & Fundamental Performance Traits

Our hot rolled H beams are produced with carefully selected low carbon structural steels, each grade conforming to corresponding national and international standards, with consistent chemical composition, controllable impurity content and superior mechanical indicators, ensuring stable and reliable performance in practical applications. The core characteristics of the adopted steel grades are detailed as follows:

A36 (ASTM Standard): As a classic low carbon structural steel under American ASTM standards, A36 is renowned for its universal applicability, excellent ductility and weldability, with moderate tensile and yield strength that meets routine construction demands. It features outstanding machinability, supporting smooth cutting, welding, drilling and bending operations, and exhibits strong adaptability to various construction environments, making it a mainstream choice for general structural engineering projects.

SS400 (JIS Standard): A representative low carbon structural steel under Japanese Industrial Standards, SS400 boasts stable mechanical properties, high toughness and exceptional forming performance. With balanced strength and plasticity, it resists cracking during processing and installation, and delivers durable service performance in conventional building and engineering structures. This grade is widely favored for its reliable quality and cost-effective production, suitable for general load-bearing frameworks and auxiliary structural components.

Q235B (Chinese National Standard): A commonly used low carbon structural steel in global engineering, Q235B offers a minimum yield strength of 235MPa, paired with good weldability, cold bending performance and impact resistance at room temperature. It features high material utilization rate and economical production costs, and complies with international structural steel application norms, perfectly catering to the design and construction requirements of general industrial buildings, civil structures and infrastructure projects.

Standardized Specifications & Hot Rolling Manufacturing Advantages

Our hot rolled low carbon H beams cover three highly demanded specifications: 200*100mm, 200*200mm and 244*175mm, all manufactured in strict accordance with unified dimensional tolerances, featuring uniform flange width, web thickness and cross-sectional symmetry. The precise dimensional control ensures seamless on-site splicing, installation and fitting, effectively reducing construction errors and improving construction efficiency. Adopting advanced hot rolling technology, these H beams are formed through high-temperature rolling and precision shaping, resulting in dense internal grain structure, smooth surface finish and no internal defects such as pores or cracks. Compared with welded profiles, hot rolled H beams feature higher structural integrity, stronger bending and compression resistance, and more stable load-bearing capacity, fully meeting the stress requirements of structural components.
