The structural steel beams H-beams and I-beams are commonly used in building applications. Due to the tremendous strength they impart and the simplicity of construction, they are frequently employed in the construction of homes, bridges, huge trailers, and other structures.
The main difference between I-beams and H-beams is their cross-section. Both share a vertical component called the “web” and a horizontal component called the “flange.” The flanges are designed to withstand the majority of the bending moment passing across the steel beam, while the web resists shear stresses.
The key distinctions between steel H-beams and I-beams used in the building sector are covered in this article.
What is H Beam?
Steel beams known as “H-Beams” are rolled steel structures shaped like the letter “H.” They are created in the form of built-up units. The H-section is created by welding the flanges to the web. Wide flange beams is another name for H-beams.
What is I Beam?
Steel is formed into I-shaped beams known as I-Beams by milling or rolling the metal. It is manufactured entirely out of a single piece of aluminum or metal.
H-Beam vs I-Beam: Cost
In terms of cost per unit of structural support, H-beams are less expensive than I-beams.
Two distinct types of structural steel members that are frequently utilized in construction are H beams and I beams. They can be distinguished from one another by their shapes. An I beam has a cross-section that resembles the letter “I” with a single vertical web or web thickest at mid-span, two webs, and no bottom flange. An H beam has a shape similar to the letter “H” with one vertical flange and two long-side flanges.
Although the dimensional parameters of these steel pieces are different, they share similar mechanical qualities.
H-beams are more effective than I-beams because they can support bending and shear loads more effectively. H-beams are better able to withstand the weight of an object placed on top of them because their web is thicker and deeper. This aids in balancing any future cantilevered loads (such added floors or beams) that might be placed on an H-beam. In addition to having a higher section modulus, which makes them more resistant to compression forces than I-beams, they also have higher tensile strength values, which reduces the likelihood that they would bend when under strain.
The web of an H-beam is far thicker than that of an I-beam, which is the primary distinction between the two types of beams. A thicker web results in a stronger beam, which increases the beam’s capacity to support loads. This means that you can need fewer H beams than I beams to provide the same amount of structural support.
Another difference between these two types of beams is that, as opposed to the majority of other beam types (such as T or L), which are often straight up and down, H beams are bent outward at both ends to generate flanges and webs that run parallel to one another along their length. They are best suited for carrying bending loads because of their structure, which also allows them to carry shear loads more effectively than any other type because they evenly distribute stress along their entire length rather than concentrating it at one end where it could easily snap off due to fatigue failure.
H-Beam vs I-Beam: Applications
Although H and I beams are extremely similar, they are used for different purposes. What you should know if you want to use one of them for your next project is as follows:
Consulting a specialist is the best method to decide which beam is appropriate for your project. I-beams are better adapted to sustain the weight of a wall or column, whereas H-beams are better suited to hold the load of the floor and roof across longer distances.
If you choose an I-beam or an H-beam, keep in mind that they have different minimum spans. If your area has a huge span, such as if it is long, an I-beam might not be the best choice because it uses more material than other designs.
H-Beam vs I-Beam: Projects
The bending, buckling, and torsional deformation of H-beams and I-beams are all too common. Buildings can be constructed using H-beams because they can withstand tension stresses in compression or shear through their sides. It is perfect for architectural designs that need for support for vertical loads like cables or girders since it has the capacity to endure both tension and compression.
Due to their capacity to withstand lateral stresses from wind or earthquakes without buckling under pressure, I-beams are frequently utilized as structural elements in large buildings.
I-Beams are better designed to support heavier loads over a beam span or length.
I-beams may be a better option if you need a structural member that can support heavy loads because they are made to carry heavier loads throughout a beam span or length.
I-beams are more bending-resistant than H-beams because of their flanges, which resist loads and support one another as the beam bends. Due to the lack of this benefit, an H-beam’s flanges have a propensity to bow under heavy loads and fail more easily under bending stress.

H-Beam vs. I-Beam: Versatility and Structural Differences for Various Applications
Both the I-beam and the H-beam are extremely adaptable and have a wide range of uses.
Both of these are structural steel beams that were created to support constructions like skyscrapers.
These two varieties of beams primarily differ in shape. In contrast to a “H” beam (thus the name), a “I” beam has a triangular cross-section.
An “H” beam typically has a greater length than a “I” beam of same size and weight capacity, which is another distinction between the two. Because of its increased stiffness (less flexibility), an H-beam will require more space when erected, but it also gives more strength for carrying big loads over long spans or lengths, whereas an I-beam might be better suited to handle lower loads over shorter span lengths.
As a result of their larger weight and rigidity, H beams are typically thought to be more durable than I beams. However, there are a number of factors, such as the manufacturing procedure, material composition, and design, that can affect a beam’s performance and strength. Engineers and designers must ultimately decide which kind of beam is best for a certain application.
