What is an H-Beam?
An H-beam is a structural beam that is shaped like an H and gets its name because it looks like a capital H over its cross-section. H beam is made of rolled steel and incredibly strong.
Details about H Beam
- The web of the H beam is thicker and, therefore, more stronger.
- H beam flanges and the web have what is called a bevel, in which three pieces of metal come to join and, in the end, appear like a single piece of metal.
- It has a bottom and top flange that protrude further from the web when compared with the I -beam flanges.
- H-beam cross-section can bear the direct load and tensile stress and resist twisting as the cross-section is wide.
- H-beam is best for bridges, columns, mezzanines, beams, platforms, and for commercial and residential building structures.
- The flanges on an H-beam are longer and stick out further from the center web.
- H-beams can be built up to any size or height and can be used for spans up to 330 feet.
- When compared, H-beams weighed is higher than I-beams with the same specifications.
- Again, H-beams are built up rather than milled.
- The distance from the end of the H beam flange to the beam center web is longer on an H-beam when the same comparison is made on the I-beam flange.
What is an I-Beam?
An l -beam is a structural beam shaped like an I and consists of two horizontal planes called flanges that are connected by one vertical component called a web. These particular beams have tapered edges, and they get their names from the fact that it looks like a capital I when viewed from its cross-section. An I-beam has a higher height of the cross-section than the width of its flange.
Difference Between H Beam and I Beam / H Beam vs I Beam
|Weight and Load of Beam
|The H-beam is often a lot heavier than the I-beam, which means it can take more force
|With some buildings where weight and force on a wall may pose a structural issue, the I-beam may be better since it is often lighter.
|Center Web of the Beam
|An H-beam has a thicker center web, which means it is often stronger.
|An I-beam often has a thinner center web, which means it is often not able to take as much force as an h-beam.
|Built-Up of Beam
|An H-beam can possibly be built up which means it can be built up to any size or height.
|An I-beam can only be built up as much as the manufacturer’s milling equipment allows.
|Beam ‘s Span
|H-beams can be used for spans up to 330 feet.
|An I-beam may be used for spans of between 33 and 100 feet.
|Flanges of the Beam
|H-beams have top and bottom flanges that stick out further from the web than the flanges on I-beams
|I-beams have top and bottom flanges, and they are shorter and are not as wide as H-beams.
|H-beam steel is economical section steel with better mechanical properties in section than I-beam
|Not economical when compared with H Beam
| H Beam can be used as a load-bearing column, and it is stable.
|I-beam alone cannot meet the stability demand because even thicken I-beams are unstable when used in load-bearing columns.
|Has an H Shape when viewed from the cross section
|Has an I Shape when viewed from the cross section
|Flange Lateral Stiffness
|The flanges of hot-rolled H-beam steel is wider than that of I-beams, have greater lateral stiffness, and are more resistant to bending.
|A narrow flange has less lateral stiffness with resistance to bending.
|Number of Pieces
|The H-beam looks like one piece of metal, but it has a bevel where three pieces of metal come together.
|An I-beam is not made by welding or riveting metal sheets together and is only one piece of metal throughout.
|The I-beam is fabricated by milling or rolling the steel.
|The I-beam is fabricated by milling or rolling the steel
|H-beam steel can be used for load-bearing columns.
|I-beam can only be used for beams.
H-beams and I-beams are both types of structural steel beams used in construction. The main difference between them lies in their cross-sections. H-beams have a thicker web and parallel flanges, while I-beams have a thinner web and tapered flanges.
H-beams are better at carrying bending and shear loads due to their greater section modulus and tensile strength. They are often used as beams in construction. On the other hand, I-beams are more suited for support frames and columns.
They are lightweight and can withstand both tension and compression forces. H-beams are generally used for longer spans, while I-beams are used for shorter spans.
Overall, both beams have their own advantages and are commonly used in different construction applications.

Structural Steel Beams: H Beam vs I Beam Strength Comparison
When it comes to comparing the strength of H beams and I beams, their different cross-sections play a crucial role. H beams, with their thicker web and parallel flanges, possess greater strength to resist bending and twisting forces.
This is attributed to their higher moment of inertia and lateral stiffness, which make them highly resistant to bending.
On the other hand, I beams, with their thinner web, are less efficient in resisting bending compared to H beams. However, I beams still have the capacity to carry heavy loads and withstand both tension and compression forces.
The choice between H beams and I beams ultimately depends on the specific requirements of the construction project and the type of loads they need to support. H beams are typically more suitable for longer spans and heavier loads, while I beams are better suited for shorter spans and lighter loads.
It is important to carefully consider the design and aesthetic aspects of the structure as well. H beams offer a more optimized cross-section, providing superior mechanical properties that make them ideal for applications where greater strength is required.
Ultimately, the decision between H beams and I beams should also take into account factors such as cost and availability. H beams are generally more economical and readily available, making them a preferred choice in many construction projects.
On the other hand, the availability of certain sizes of I beams may be limited. When making the choice, it is crucial to assess and balance the load requirements, design preferences, and cost considerations to ensure the best fit for the construction project.
