HEA340 HEB340 S275JR S355J2 12m H Beam Structure

H-section steel beam size and performance comparison
HEA340 and HEB340 have the same nominal height and width (i.e. 340mm), but there are significant differences in their web thickness, flange thickness and weight per meter. HEB340 has increased these aspects compared to HEA340.

Cross-sectional area and moment of inertia: HEB340 is not only heavier than HEA340, but also has a larger cross-sectional area and moment of inertia, which can provide higher load-bearing capacity and better bending resistance.

Material differences of steel h profile
S275JR h steel profile: This is a basic carbon structural steel with a yield strength of 275 MPa, suitable for general construction purposes.
S355J2 h shape metal: This steel is a high-strength low-alloy structural steel with a yield strength of 355 MPa and good low-temperature toughness, suitable for applications requiring higher strength and cold resistance.

Applicable scenarios of h beam section
HEA340 h profile steel: Suitable for building structures with medium to heavy loads, such as beams or columns in multi-story buildings, light industrial plants, etc.
HEB340 h beam profile: Due to its higher load-bearing capacity and rigidity, it is more suitable for heavy industrial buildings, high-rise buildings or other projects with high requirements for structural stability and strength.
