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.
