Our HEA/HEB450 H beams are fabricated from S275JR steel, a low-alloy structural steel that fully complies with EN10025 and DIN1025 standards. S275JR is renowned for its outstanding comprehensive mechanical properties, featuring a minimum yield strength of 275 MPa (at thickness ≤16mm) and a tensile strength range of 370-530 MPa. This grade of steel offers excellent weldability, formability, and impact toughness (tested at 20℃), ensuring stable performance in various construction environments. Compared to ordinary carbon steel, S275JR's low-alloy composition enhances its structural stability and durability, making it suitable for heavy-duty structural applications that require high reliability.

The HEA450 and HEB450 specifications belong to the European standard wide-flange H beam series, with "450" indicating the nominal height of the cross-section (450mm). HEA (European Wide Flange Beams, Series A) is characterized by a relatively lightweight design with thinner flanges and web, offering an optimal strength-to-weight ratio for general structural applications. HEB (European Wide Flange Beams, Series B) features thicker flanges and web, providing higher load-bearing capacity and torsional rigidity, ideal for heavy-duty structures and large-span projects. Both specifications adopt a symmetrical "H" cross-sectional design, ensuring uniform stress distribution and excellent bending resistance. As hot rolled products, these H beams possess a dense internal structure and superior mechanical properties compared to cold-formed products, further guaranteeing structural safety.

As a direct factory supplier, we implement a stringent full-process quality control system to ensure the excellence of our DIN1025/EN10025 S275JR HEA/HEB450 H beams. The production process covers rigorous raw material inspection (chemical composition and mechanical property verification of S275JR steel billets), precise hot rolling process control (strict monitoring of rolling temperature, speed, and deformation to ensure dimensional accuracy), and comprehensive final testing (including yield strength, tensile strength, impact toughness, dimensional tolerance, and surface quality inspection). All finished products are certified to meet or exceed EN10025 and DIN1025 standards, providing customers with reliable quality assurance. With large-scale production capacity and sufficient inventory, we can fulfill bulk orders efficiently and deliver timely to meet the urgent needs of various projects.

Our S275JR HEA/HEB450 hot rolled H beams are widely suitable for large-scale construction projects such as high-rise building frames, large-span bridges, industrial workshops, stadiums, and infrastructure facilities. Backed by our professional technical team, we provide comprehensive technical support, including material performance consultation, specification selection guidance, and structural design advice. As a factory direct supplier, we offer competitive pricing while ensuring product quality, helping customers reduce procurement costs. We are committed to establishing long-term and stable cooperative relationships with global customers by delivering high-quality H structure steel and professional services.
