H-beam Size Chart – What Is Piping

Both H-beam and I-beams are structural steel materials used widely in the construction industry by civil engineering professionals. By a novice, both these members may seem to be similar. The horizontal elements of the I and H beam are known as flanges, while the vertical element is called as the "web". The web resists shear forces, and the flanges are designed to resist most of the bending moment that the beam experiences. In general, The design of both I-beam and H-beam are governed by any of the following criteria: deflection: Target criteria should be to minimize deformationvibration: the stiffness and mass are should be decided based on vibration tendency.bending failure by yieldingbending failure by lateral torsional bucklingbending failure by local bucklinglocal yield due to high magnitude of concentrated loads.shear failurebuckling or yielding of components However, both are quite different from one another. In this article, We will explore the main differences between I-beam and H-beam. What is an H-beam? H-beam is an incredibly strong structural steel member. As the cross-section of this beam resembles the capital letter "H", it is known as H-beam. Fig. 1 shows a typical example of an H-beam. Fig. 1: H-beam Example H-beams have an equal thickness in the two parallel flanges without any taper on the inside surface. Depending on the height and flange width; H-beams are classified into three categories. They are Wide Flange Series H-beamMedium Flange Series H-beam andNarrow Flange Series H-beam.

I-beams are also structural steel members but their cross sections resemble the capital letter "I". Consisting of two flanges and one web, an I-beam has a slope on the inner surface of the flanges. Depending on the use, I-beam sections are available in a range of weights, flange widths, section, depth, web thickness. Fig. 3 below shows a typical example of I-beams.

In an I-beam, the size of the web is greater than the size of the flange whereas in an H-beam it may not be true. H-beam vs I-beam: Mechanical Properties The cross-section of the I-beam is poor against twisting as compared to H-beam.In general, H-beams are more rigid and can carry more load as compared to I-beams.H-beams are used as columns while I-beams are used as beams. H-beam vs I-beam: Manufacturing An I-beam is manufactured as a single piece throughout, but an H-beam is normally manufactured by welding 3 pieces of metal.An H-beam can be produced to any desired size and height whereas the production of I-beams is limited by the milling machine capacity.
