The difference between I-beam and H-beam
The choice of using I-beams or H-beams should be weighed and decided based on comprehensive factors such as specific project needs, budget, design and construction conditions.
The main differences between I-beams and H-beams are their cross-sectional shape, performance characteristics, application areas and cost.
Cross-sectional shape: The cross-section of I-beam is I-shaped, and its flange is a variable cross-section. The part near the web is thicker and the outer part is thinner; while the cross-section of H-beam is H-shaped, and its flange is a constant cross-section.
Performance characteristics: The I-beam has small side length and large height, and can only bear forces in one direction, so it is suitable for structures such as beams; H-shaped steel has deep grooves and large thickness, and can withstand forces in both directions, so it is suitable for structural load-bearing columns. wait. The flange of H-shaped steel is wider than that of I-shaped steel, with greater lateral stiffness and stronger bending resistance. The physical weight of H-shaped steel is lighter than that of I-shaped steel under the same specifications.
Application fields: I-beams can be used in various building structures, bridges, supports, machinery and other fields; H-beams are suitable for industrial building structures, civil building structures, underground construction projects and highway baffle supports and other fields.
Cost: With the same amount of steel used, H-shaped steel can withstand greater rigidity and stability than I-beam, and its torsion resistance and bending resistance are better than I-beam. However, H-beams usually cost more than I-beams because H-beams weigh more.
In summary, the choice of using I-beams or H-beams should be weighed and decided based on comprehensive factors such as specific project needs, budget, design and construction conditions.
