S355JR UB 457*152*74 Beam Structural Section
Chemical composition of S355JR structural steel beam: carbon (C) content ≤0.22%, silicon (Si) content ≤0.55%, manganese (Mn) content ≤1.60%, phosphorus (P) content ≤0.025%, sulfur (S) content ≤0.025%.
Mechanical properties of S355JR h metal beam: It belongs to low-alloy high-strength structural steel with a minimum yield strength of 355MPa. When the thickness of the steel plate is ≤16mm, the yield strength is ≥355MPa; when the thickness is 16-40mm, the yield strength is ≥345MPa. The tensile strength is generally between 470-630MPa,
UB means general beam steel. UB 457x152x74 universal steel beam represents the specifications of the steel section, where 457mm is the height of the steel section, 152mm is the width of the flange, and 74kg/m is the weight of the steel section per meter.
UB 457x152x74 universal beam sectional characteristics: It has a narrower wing plate and a wider web, suitable for structures that bear longitudinal tension and bending forces; the cross-sectional shape has good performance in bending and shear resistance, can effectively share the load, and enhance the strength and stability of the overall structure.
UB 457x152x74 Hot-rolled Universal Beam Application Fields
Building Structure: Commonly used in the load-bearing of beams, columns and trusses in large-span structures such as high-rise buildings, industrial plants, and gymnasiums. It can effectively support the weight of the building and improve the safety and durability of the structure.
Bridge construction: It can be used as the main beam and supporting structure of the bridge, using its high strength and good earthquake resistance to bear the weight of the bridge itself and the load of vehicles, etc., to ensure the safe use of the bridge.
Machinery manufacturing: It can be used to manufacture key load-bearing components in heavy equipment such as crane arms, excavator parts, and agricultural machinery, ensuring that the equipment can withstand large loads without deformation during operation.
