W30x148 W30x173 Flange H Beam Steel Sections
W30x148 and W30x173 structural steel beams are American standard wide flange H-beams. The implementation standard is ASTM A6/A6M, which specifies the technical requirements for the size, shape, weight and allowable deviation of American standard H-beams.
W30x148 W30x173 h steel profile Taking the common material A36 as an example, the chemical composition range is: C: 0.27~0.35; Si: 0.93~1.20; Ni: ≤0.029; Cu: ≤0.025; Mn: 0.80~1.10; Cr: 0.75~1.20.
W30x148 W30x173 h beam section Taking the common material A36 as an example, the tensile strength σb (MPa) ≥560; yield strength σs (MPa) ≥460; elongation δ5 (%) ≥10; cross-sectional shrinkage ψ (%) ≥45; impact energy Aku (J) ≥39; impact toughness value αkv (J/cm²) ≥49; hardness ≤229HB.
Features of W30x148 W30x173 steel h profile
High strength: The special "H" section design has strong bending resistance in all directions, can withstand large loads and pressures, and is suitable for building structures with high requirements for bearing capacity.
Simple construction: All parts of the steel are arranged at right angles, which is easy to process and install, can save welding and riveting workload, can effectively shorten the construction period and reduce construction costs.
Light structural weight: Compared with ordinary I-beams, under the same bearing capacity, the cross-sectional area distribution of American standard H-beams is more optimized, the strength-to-weight ratio is more reasonable, and the building structure can be reduced by 30%-40%.
Uses of W30x148 W30x173 h steel profile
It is often used in large buildings that require large bearing capacity and good cross-sectional stability, such as structural support and frame construction of factories, high-rise buildings, etc. It is also widely used in the main beams, cross beams and supporting structures of bridges, as well as shipbuilding, lifting and transportation machinery, equipment foundations, brackets, foundation piles and other fields.
