100*90*5000mm 125*75*3000mm S235 S275 S355 Bright Hot Rolled Steel H Beam

Our bright hot rolled steel H beams are engineered to deliver exceptional performance and precision, available in standardized specifications of 100*90*5000mm and 125*75*3000mm, with premium material grades including S235, S275, and S355. As high-quality structural components, these H beams combine the advantages of bright hot rolling technology with the reliable mechanical properties of European standard structural steels, making them ideal for diverse industrial, construction, and precision engineering applications that demand strict dimensional accuracy and superior surface quality.

The specified dimensions of our H beams-100*90*5000mm and 125*75*3000mm (representing flange width * web height * length)-are carefully calibrated to meet precise structural design requirements. The optimized H-shaped cross-section, characterized by robust flanges and a rigid web, ensures excellent load-bearing efficiency: the flanges provide strong resistance to bending and axial compression, while the web effectively transfers shear forces, guaranteeing structural stability under various load conditions. These fixed-length specifications (3000mm and 5000mm) eliminate the need for additional cutting in most scenarios, improving construction and assembly efficiency, and reducing material waste. The bright surface finish, a hallmark of the advanced bright hot rolling process, ensures a smooth, defect-free appearance and tight dimensional tolerance, enhancing both aesthetic performance and compatibility with other structural components.

The S235, S275, and S355 European standard structural steel grades form the core of our H beams' reliable performance. S235, a widely used carbon structural steel, offers a minimum yield strength of 235 MPa and excellent ductility and weldability, suitable for general structural applications. S275 provides enhanced strength with a minimum yield strength of 275 MPa, catering to projects with moderate load-bearing requirements. S355, a high-strength structural steel grade, boasts a minimum yield strength of 355 MPa and superior toughness, making it ideal for heavy-duty, high-stress environments. All three grades feature strictly controlled chemical compositions, ensuring good machinability and fatigue resistance. Their compatibility with common welding methods (arc welding, gas welding, etc.) allows for flexible fabrication and on-site assembly, adapting to diverse project needs.

The bright hot rolling manufacturing process is instrumental in achieving the superior quality of our H beams. Unlike conventional hot rolling, bright hot rolling involves precise temperature control and advanced surface treatment technologies during production. Steel billets are heated to optimal temperatures (1100-1250°C) and subjected to continuous rolling, followed by surface brightening treatments that remove oxide scales and impurities. This process not only refines the steel's grain structure, eliminating internal defects such as porosity and segregation, but also creates a smooth, bright surface with tight dimensional accuracy (tolerance within ±0.5mm for key dimensions). The refined microstructure enhances the H beams' tensile strength, toughness, and wear resistance, while the bright surface reduces the need for additional surface finishing, lowering project costs and shortening construction cycles.

Our S235/S275/S355 bright hot rolled steel H beams (100*90*5000mm, 125*75*3000mm) are widely applied in precision engineering, industrial workshops, commercial buildings, mechanical equipment frames, bridge auxiliary structures, and residential construction. They serve as core load-bearing components such as floor beams, girders, brackets, and framing members, delivering consistent performance and reliability. We implement rigorous quality control measures throughout the production process-from raw material inspection and chemical composition analysis to mechanical property testing (tensile, yield, impact), dimensional verification, and surface quality assessment. Every batch of H beams is certified to meet European EN standards, ensuring compliance with international quality and safety requirements. By offering these high-precision, high-quality bright hot rolled H beams, we provide customers with reliable structural solutions that balance performance, efficiency, and cost-effectiveness.
