The question of the day! Do you know how H-beams and I-beams are used differently? Keep reading and we will help you answer this important question. In the construction industry, many people still cannot explain this information properly. Steel beams are extremely important to understand because they support heavy loads.
What is an H-Beam?
H-beams are shaped like an H. H-beam is a structural beam made of rolled steel. It is incredibly strong. It gets its name because it looks like a capital H over its cross section.
What is an I-Beam?
An l -beam is shaped like an I. The I beam consists of two horizontal planes, known as flanges, connected by one vertical component, or the web. I-beam has tapered edges and it gets its name from the fact that it looks like a capital I when you see it from its cross section. With an I-beam, the height of the cross section is higher than the width of its flange.
H-Beam vs I-Beam: Weight
H-beam: The H-beam is often a lot heavier than the I-beam, which means it can take more force.
I-beam: 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.
H-Beam vs I-Beam: Center Web
H-beam: An H-beam has a thicker center web, which means it is often stronger.
I-beam: 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.
H-Beam vs I-Beam: Built-Up
H-beam: An H-beam can possibly be built up which means it can be built up to any size or height.
I-beam: An I-beam can only be built up as much as the manufacturer’s milling equipment allows.
H-Beam vs I-Beam: Spans
H-beam: H-beams can be used for spans up to 330 feet.
I-beam: An I-beam may be used for spans of between 33 and 100 feet.
H-Beam vs I-Beam: Flanges
H-beam: H-beams have top and bottom flanges that stick out further from the web than the flanges on I-beams.
I-beam: I-beams have top and bottom flanges, and they are shorter and are not as wide as H-beams.
H-Beam vs I-Beam: Number of Pieces
H-beam: The H-beam looks like one piece of metal but it has a bevel where three pieces of metal come together.
I-beam: An I-beam is not made by welding or riveting sheets of metal together and is only one piece of metal throughout.
What Are I-Beams Used For?
I-beams have a variety of important uses in the structural steel construction industry. They are often used as critical support trusses, or the main framework, in buildings. Steel I-beams ensure a structure’s integrity with relentless strength and support. The immense power of I beams reduces the need to include numerous support structures, saving time and money, as well as making the structure more stable. The versatility and dependability of I-beams make them a coveted resource to every builder.
Commonly termed an “I” beam because of its shape, beams provide great load bearing support when used horizontally or standing as columns. I-beams are the choice shape for structural steel builds because the I-beam makes it uniquely capable of handling a variety of loads. The shape of I-beams makes them excellent for unidirectional bending parallel to the web. The horizontal flanges resist the bending movement, while the web resists the shear stress.
Understanding the I-beam is a basic necessity for the modern civil engineer or construction worker. Engineers use I-beams widely in construction, forming columns and beams of many different lengths, sizes, and specifications.
An I-beam is made by rolling or milling steel which means the I-beam is often limited by the capacity or size of the milling equipment.
I-beams come in a variety of weights, section depths, flange widths, web thicknesses, and other specifications for different purposes. When ordering I-beams, buyers classify them by their material and dimensions. For example, an 11×20 I-beam would have an 11-inch depth and a weight of 20 pounds per foot. Builders choose specific sizes of I-beams according to the needs of the particular building. A builder has to take many factors into account, such as:
- The builder chooses an I-beam with a web thickness that won’t fail, buckle, or ripple under tension.
- The flanges are chosen to prevent buckling locally, sideways, or torsionally.
- The builder will choose a thickness to minimize deformation of the beam.
- A certain mass and stiffness are selected to prevent vibrations in the building.
- The strength of the I-beam’s cross-section should accommodate yield stress.
