HEA280 HEB280 Steel Profile H beam S355JR/S355JO
HEA280 European standard H-beam: height is 270mm, width is 280mm, web thickness is 8mm, flange thickness is 13.0mm, and weight per meter is about 76.4kg.
HEB280 H-beam: height and width are both 280mm, web thickness is 10.5mm, flange thickness is 18mm, and weight per meter is about 103kg. In comparison, HEB280 has thicker webs and flanges, and is heavier overall.
Both are usually made of similar steel materials, such as S235JR, S275JR, S355JR, etc. However, due to the larger cross-sectional size of HEB280 h type steel beam, its mechanical properties such as bearing capacity, bending resistance and shear resistance are better than HEA280, and it can withstand greater loads and stresses.
HEA280 h shaped iron beam: Due to its light weight and relatively small cross-sectional size, it is suitable for some building structures that have certain weight requirements and are not particularly large loads, such as the frames of commercial and residential buildings, the supporting structures of roofs and floors, etc. It can also be used in some places with high space requirements and require more flexible structural layout.
HEB280 h shaped steel beam: Due to its high strength and bearing capacity, it is often used in large industrial buildings, bridge projects, heavy equipment foundations, and high-rise buildings that need to withstand large loads. For example, the supporting columns of the core tube structure and the main beams of large-span bridges.
