This article will let Baowu show you the difference between I-beam and H-beam.

First of all, I-beam and H-beam are different in shape. The cross-section of I-beam is "I"-shaped, and the cross-section of H-beam is similar to the letter "H".

The thickness of the flange plate of I-beam is not equal. Its flange part will be narrower, and the closer it is to the web, the thicker it will be, so it can only bear the force from one direction; while the thickness of the flange plate of H-beam is all the same, so he can withstand forces from different directions.

Finally, I-beams and H-beams are used for different purposes. I-beams are suitable for various buildings, and the application range of bending members in planes is very limited. H-beams are used for beams, column members in industrial and civil building steel structures, steel structure load-bearing brackets for industrial structures, etc.

Whether the I-beam is ordinary or light, due to the relatively high and narrow section size, the moment of inertia of the two main sleeves of the section is quite different. Therefore, it can generally only be directly used in the plane of its web. Bending members or forming lattice-type stress members. It is not suitable to use axial compression members or members that are perpendicular to the plane of the web and bend, which makes it very limited in the scope of application.

H-beams are high-efficiency and economical cutting profiles. Due to their reasonable cross-sectional shape, they can make the steel perform better and increase the bearing capacity. Different from the ordinary I-shaped, the flange of the H-beam is widened, and the inner and outer surfaces are usually parallel, which can facilitate the connection of high-strength screws and other components. Its size constitutes a fair series, and the models are complete, which is convenient for design and selection.

The above is the difference between I-beam and H-beam. If you buy, you can choose the corresponding steel according to your actual situation and use.
