H Beam Steel HEA280 HEB280 S275JR/S355JR
HEA280 steel beam Application scenarios: Lightweight frames (e.g. secondary beams in low-rise buildings); non-critical supports (e.g. platforms, auxiliary structures).
HEB280 universal beam Application scenarios: Heavy-duty structures (e.g. main beams in high-rise buildings, crane girders); critical components (e.g. bridge piers, heavy machinery bases).
Structural characteristics and applicable scenarios HEA280: Narrow flange design, thin web and flange, suitable for light loads or scenarios with strict restrictions on section height (such as light frames, auxiliary supports).
HEB280: Medium flange design, with larger section height and flange/web thickness, stronger bending and compression resistance, suitable for heavy-load structures (such as high-rise building main beams, heavy equipment bases).
