I-beams are similar in shape to H-beams, but they have different properties and uses. Let's take a look at the difference between H-beam and I-beam.

What is I-beam Steel?

As the name suggests, these steel beams are shaped like a capital "I." They are often used in industrial applications and have tapered flanges. I-section steel beams come in two different styles, one with parallel flange surfaces (wide) and the other with sloped inner flange surfaces (S-shaped beams).

What is H-beam Steel?

These are usually heavier and longer than I-beams. Looking like a capital "H", they have longer flanges. Often the term is used interchangeably with I-beam, so it can sometimes be confusing. In many cases, the web and flange of an H-beam have the same thickness.

H-beams and I-beams are not only slightly different in shape, but also have great differences in weight, strength, flange design, and some other characteristics and applications.

Differences Between I-Beam and H-Beam

1. The flange of H-beam is longer, wider and heavier than I-beam, but it can be used interchangeably in most cases. Flanges are the horizontal elements at the top and bottom of the beam.

2. The section size of the I-beam is relatively high and narrow, and the moments of inertia of the two main sleeves of the section are quite different. The cross-sectional shape of H-shaped steel is more reasonable, and the bearing capacity is improved more effectively.

3. H-beams are stronger than I-beams. The web of the H-beam is thicker, which refers to the height of the beam.

4. Welding I-beam is easier than I-beam. The H-beam looks like three pieces of metal spliced together, while the I-beam is a whole piece of metal. The flange of the H-shaped steel is of equal thickness, including rolled profiles and composite profiles welded by 3 plates.

5. I-beams are generally lighter than I-beams.

6. I-beams can only be directly used for web bending components, so they are mostly used in civil projects such as steel structures and bridges, while I-beams are suitable for platforms, bridges, and some residential and commercial buildings. I-beams can only be used for beams, and H-beams can only be used for load-bearing columns of structures.

7. H-beams can be installed in any size and height, but I-beams are limited to equipment.
