Construction Structural Hot Rolled H Beams 100 mm 20mm S235jr A36 S275jr Ss400 Mild Steel I Beam Hea Heb Ipe H Beam

Our Construction Structural Hot Rolled H Beams, available in standardized dimensions (100 mm, 20 mm) and a comprehensive range of mild steel grades including S235JR, A36, S275JR, and SS400, represent the pinnacle of reliability and versatility for structural engineering applications. Fabricated via advanced hot rolling technology, these beams possess superior structural integrity, uniform material composition, and enhanced mechanical properties that set them apart from cold-formed alternatives-making them the preferred choice for load-bearing frameworks in commercial, industrial, and infrastructure construction.

The product line encompasses a full spectrum of H-beam and I-beam profiles, including HEA (European Wide Flange Beams), HEB (European Broad Flange Beams), IPE (European IPE Beams), and standard I-beam configurations, each tailored to specific structural requirements. The hot rolling process, which involves shaping steel at elevated temperatures (typically above 1000°C), imparts excellent ductility and formability to the beams, allowing for seamless fabrication, welding, and customization such as cutting, drilling, and bending to fit unique project designs. This process also eliminates internal stresses, ensuring dimensional stability and long-term structural performance under dynamic and static loads.

A key advantage of these beams lies in the diverse selection of mild steel grades, each engineered to meet international standards and specific performance criteria. S235JR, a European standard non-alloy structural steel, offers a minimum yield strength of 235 MPa and excellent weldability, ideal for general structural applications. A36, a widely recognized American standard carbon steel, boasts a minimum yield strength of 250 MPa and balanced tensile strength (400-545 MPa), suitable for high-load scenarios. S275JR, with a higher minimum yield strength of 275 MPa, delivers enhanced load-bearing capacity for heavy-duty structures, while SS400 (Japanese standard) provides reliable performance with a yield strength of 245 MPa, catering to global construction demands.

The specified dimensions (100 mm, 20 mm) reflect the beams' critical cross-sectional parameters, with flange widths, web thicknesses, and overall depths optimized to ensure efficient stress distribution. The H-beam's iconic cross-sectional design-featuring two parallel flanges connected by a central web-delivers exceptional bending stiffness, torsional resistance, and axial load-bearing capacity. This geometric advantage ensures uniform stress transfer under complex loading conditions (axial, bending, shear), making these beams suitable for primary structural members such as columns, girders, beams, and trusses in high-rises, warehouses, bridges, power plants, and residential complexes.

All our hot rolled H beams and I beams undergo rigorous quality control protocols, including chemical composition analysis, mechanical property testing (tensile strength, yield strength, elongation), and dimensional accuracy verification, to comply with international standards (EN 10025 for S235JR/S275JR, ASTM A36 for A36, JIS G 3101 for SS400). The mild steel composition-characterized by low carbon content (typically ≤0.25%) and controlled levels of impurities-ensures excellent weldability compatibility with standard welding processes (arc welding, MIG/MAG welding, TIG welding) and resistance to atmospheric corrosion when properly coated.

Whether for large-scale infrastructure projects requiring high-strength S275JR beams or general construction utilizing cost-effective S235JR or A36 beams, our hot rolled H beams and I beams provide engineers and contractors with a flexible, high-performance solution. Their combination of standardized quality, diverse material grades, multiple profile options, and superior fabrication capabilities makes them indispensable for constructing safe, durable, and cost-efficient structures that meet the demands of modern construction.
