100mm steel beam is an economical and efficient structural section, named for its cross-section resembling the letter "H". It is renowned for its optimized sectional shape and excellent strength-to-weight ratio, offering outstanding load-bearing capacity and stability in both principal planes (strong and weak axes). Our 300mm steel beam are the ideal skeletal material for constructing industrial plants, high-rise buildings, bridges, and other large-scale structures.

Advantages of H-beam Steel
Optimal Flexural Rigidity and High Load Capacity: The H-section design concentrates material in the highest-stress areas, resulting in a large section modulus, vastly superior bending resistance, and load capacity compared to I-beams, ideal for large spans and high-rise structures.
High Efficiency and Material Savings: The scientifically engineered cross-section can save 15%-20% more metal than concrete or standard steel structures and reduces structural dead weight by 30%-40%, lowering foundation requirements and overall engineering costs.
Simplified Construction and High Stability: Uniform size and shape facilitate fast on-site assembly, connection, and installation. The structural stability, excellent plasticity, and toughness ensure strong seismic and impact resistance.
Increased Usable Building Area: Steel columns occupy less floor space than concrete columns, potentially increasing effective building area by 4%-6%, and offering greater design flexibility for interior layouts.
Manufacturing Process
H-beams are produced by hot rolling on a universal mill. Billets are reheated to 1200–1250°C and rolled in a series of passes using horizontal rolls for the flanges and vertical rolls for the web, allowing simultaneous deformation. The rolling process ensures precise control of section modulus and flange thickness. After rolling, the beam is cooled on a cooling bed, straightened by rotary straightening, and cut to length. Ultrasonic testing (UT) may be applied to critical sections.
Application Fields
Building Structures: Load-bearing members like columns and beams for industrial and civil buildings.
Bridge Engineering: Bridge piers, support structures.
Industrial Equipment: Port cranes, equipment supports, pile foundations.
Underground Engineering: Support for tunnels, subway stations.
Quality Control
Our H-beams strictly adhere to international standards like ASTM and JIS, and are certified under the ISO9001 quality management system. We provide complete material certificates and accept third-party inspections.
