HEA900 HEB900 EN wide flange H beams
HEA900 structural h beam features: narrow flange design, thin web, high bending stiffness, suitable for bearing lateral loads, suitable for scenarios that are sensitive to material costs and where the load is mainly bending force.
HEB900 structural steel h beam features: thicker flanges and webs, better shear strength and compressive stability, suitable for bearing vertical loads and dynamic shear forces; larger section inertia moment, stronger seismic performance and deformation resistance, suitable for earthquake-prone areas or scenarios with high stability requirements.
Material and mechanical properties of HEA HEB900 h beam material
Commonalities: The material is mostly S355JR h section steel beam, with a yield strength of ≥355 MPa, a tensile strength of 470-630 MPa, and an elongation of ≥21%.
Differences: HEB900 h beam steel structure has better shear strength (related to web thickness) and local compressive resistance due to thickened section.
