Beam Steel/JIS Ss400 Ss400 H Beam Q235B A36 Q345 Steel H Beam

Our premium steel H beams, available in JIS SS400, Q235B, ASTM A36 and Q345 grades, are high-performance hot-rolled carbon structural profiles engineered to meet diverse global construction, engineering and fabrication demands. As versatile and reliable beam steel products, they adhere to strict domestic and international steel standards, integrating exceptional mechanical properties, stable structural integrity and superior processability. Crafted from high-quality carbon and low-alloy carbon steel billets via advanced hot rolling technology, these H beams deliver consistent performance, robust load-bearing capacity and long service life, serving as indispensable load-bearing components for a wide spectrum of projects, from general construction to heavy-duty industrial infrastructure, and earning wide recognition across global structural steel markets.

Material Grades & Standard Compliance

These steel H beams are manufactured in strict accordance with four globally recognized material specifications, each tailored to distinct application scenarios and load requirements, ensuring full compatibility with international building codes and engineering standards. JIS SS400, complying with Japanese Industrial Standards (JIS G3101), is a general-purpose carbon structural steel with balanced mechanical properties, stable forming quality and excellent processability, widely utilized in Asian engineering projects and cross-border construction schemes. Q235B (GB/T 700), a classic Chinese carbon structural steel, features moderate strength, outstanding ductility and exceptional weldability, serving as a cost-effective solution for light-load supporting structures and routine construction works. ASTM A36 (ASTM A36/A36M), the most prevalent general structural steel standard worldwide, offers comparable performance to SS400 and Q235B, with reliable toughness and versatility, ideal for general construction and mechanical fabrication across North America, Europe and other regions. Q345 (GB/T 1591), a low-alloy high-strength structural steel, boasts elevated yield and tensile strength, enhanced impact resistance and durability, perfectly suited for medium-to-heavy load-bearing frameworks, high-rise buildings and harsh outdoor engineering environments.

Structural Design & Hot Rolling Manufacturing Advantages

Featuring a standardized H-shaped cross-section, these steel H beams are designed with optimized structural geometry, including uniform flanges, sturdy webs and precise dimensional tolerances, enabling efficient stress distribution and superior structural rigidity. Produced through professional continuous hot rolling processes, the beams undergo rigorous temperature control, precision rolling and post-processing treatments, which refine the internal grain structure, eliminate residual stress and minimize defects such as warping, cracking and surface imperfections. This specialized manufacturing process endows the products with an exceptional strength-to-weight ratio, surpassing traditional I-beams and solid steel profiles in bending resistance, lateral stability and axial load capacity. The symmetrical H-section design also facilitates convenient on-site processing, including cutting, welding, bolting and riveting, streamlining construction procedures and improving assembly efficiency.

Core Performance & Application Versatility

Rooted in the inherent properties of high-quality carbon structural steel, our SS400, Q235B, A36 and Q345 H beams exhibit remarkable comprehensive performance, with excellent weldability, machinability and formability to adapt to complex structural designs. They demonstrate strong resistance to conventional physical wear, dynamic loads and mild atmospheric corrosion, and can be further treated with anti-corrosion, anti-rust or fireproof coatings to extend service life in coastal, high-humidity and industrial environments. With multi-grade compliance and complete size ranges, these H beams are extensively applied across various sectors: residential and commercial building steel frames, industrial workshops, warehouse structures, bridge substructures, highway infrastructure, port facilities, mining support components and prefabricated building assemblies. Their wide adaptability makes them suitable for both small-scale construction projects and large-scale international engineering developments.
