S355JR S275JR HEA/HEB650 H Section Steel Beam

HEA650 h type beam and HEB650 h type steel beam are two different types of H-shaped steel manufactured according to European standards (EN), the main difference lies in the cross-sectional size and shape; S355JR material h beam and S275JR steel beam h are two different steel grades, representing different mechanical properties.

HEA650 h shaped steel beam specifications: height is about 650 mm; the flange width is narrow, suitable for occasions requiring higher lateral stability; the web thickness and flange thickness are relatively small, suitable for medium load requirements.

HEB650 h shaped iron beam specifications: height is also about 650 mm; the flange width is wider than the HEA series, which usually means better lateral stability and larger section modulus; web thickness and flange thickness: usually larger than the HEA series, so it can withstand larger loads.

Material properties of S275JR h beam material: yield strength not less than 275 MPa; tensile strength is usually between 410-560 MPa; this material is suitable for general building structures, where strength requirements are not particularly high.

Material properties of S355JR h beam steel structure: yield strength not less than 355 MPa; tensile strength is usually between 470-630 MPa; S355JR has higher strength and NMness, and is suitable for occasions requiring higher load-bearing capacity and durability.

Application scenario comparison
Application scenario of HEA650 h section steel beam: suitable for applications that require a certain support force but have certain space restrictions, such as certain types of frame structures or bridges with light to medium loads.
Application scenario of HEB650 h shaped beam: more suitable for heavy-load applications, such as heavy machinery support, long-span bridges, or other occasions requiring high load-bearing capacity.
