UB 457x191x67 457x191x74 EN S355J0 h steel profile
Chemical composition of S355J0 h-shaped 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 S355J0 steel h profile: yield strength ≥ 355MPa, tensile strength between 450 - 680MPa, elongation between 17% - 22%.
At 0℃, the longitudinal impact energy is not less than 27J, with good low-temperature toughness, can maintain good strength and toughness in low-temperature environment, and prevent material embrittlement or fracture.
UB stands for universal beam steel. For UB 457x191x67, 457mm is the height of the steel, 191mm is the width of the flange, and 67kg/m is the weight of the steel per meter; for UB 457x191x74, the corresponding parameters are 457mm in height, 191mm in flange width, and 74kg/m per meter.
Sectional characteristics of universal beam steel: It has a wider flange and a relatively narrow web. This cross-sectional shape makes it excellent in bending resistance, can effectively resist and disperse the effects of various forces, enhance the strength and stability of the overall structure, and is particularly suitable as a beam member that bears bending loads.
Application of Hot Rolled Universal Beam
Building structure: It is suitable for load-bearing parts such as beams and roof trusses in large-span structures such as high-rise buildings, industrial plants, gymnasiums, exhibition halls, etc. It can effectively support the weight of the building and improve the safety and durability of the structure. Due to its good low-temperature toughness, it can also play an important role in construction projects in cold areas.
Bridge engineering: It can be used as the main beam, secondary beam and other structural components of the bridge, bearing the weight of the bridge itself as well as the loads of vehicles and pedestrians, ensuring the safety and reliability of the bridge during use, especially suitable for bridge construction in low temperature environments.
