S355J0 UB 254x146x37 254x146x43 structural steel h beam
S355J0 steel beam is a European standard low-alloy high-strength structural steel, and the implementation standard is EN10025-2. It is an alloy steel with low carbon content (≤0.20%), and elements such as manganese, silicon, and molybdenum are added to improve performance.
Chemical composition
C≤0.20%, Mn≤1.60%, P≤0.040%, S≤0.040%, and contains trace amounts of alloy elements such as Cr, Ni, and Cu.
Mechanical properties
Yield strength: 355MPa (when thickness ≤16mm), gradually decreases to 275MPa (250mm) with increasing thickness.
Tensile strength: 470-630MPa (different thickness range).
Impact toughness: Impact energy ≥27J at 0℃, good applicability in low temperature environment.
UB 254x146x37 h section steel Specifications
Cross-sectional dimensions: height 254mm, width 146mm, web thickness 37mm, flange thickness about 37mm (please refer to British standard for details).
Weight per meter: about 37kg/m (adjusted according to thickness).
Applicable scenarios: heavy-duty shelves, industrial warehousing, bridge support, etc., with strong bearing capacity.
UB 254x146x43 h shaped steel Specifications
Cross-sectional dimensions: the same height and width as UB 254x146x37 h section steel beam, the web thickness is increased to 43mm, and the flange thickness may be adjusted to match the structural requirements.
Weight per meter: about 43kg/m (specific calculation is required).
Advantages: The thickened web improves the bending resistance and is suitable for higher load scenarios.
Features of UB 254x146x37 54x146x43 h type beam
1. H-shaped steel cross-section is optimized, with high strength-to-weight ratio, saving materials and convenient installation.
2. The difference in web thickness (37mm vs. 43mm) can meet different load-bearing requirements and flexibly adapt to engineering design.
Application areas
Industrial warehousing: core materials for heavy-duty shelves, suitable for high-density storage needs.
Buildings and bridges: beam-column structures, large factory frames, meeting earthquake resistance and high load requirements.
Machinery manufacturing: lifting equipment, engineering machinery components, such as bearing seats, brackets, etc.
