Differences Between Three Types of Surplus Steel Beams

Surplus steel beams come in a variety of shapes and sizes, with the most common being the I-beam, H-beam, and W-beam. The differences between these three are most apparent in their appearance, but the more important variation to consider is how the shape affects the strength and weight of your beams. This will help you choose the best option for your project.

Characteristics of the I-Beam

At first glance, the I-beam may look very similar to the H-beam and W-beam. If you look more closely, you’ll see the I-beam, which does have two flanges connected by the web just as the other two beams, has shorter flanges.

These shorter flanges that create the top and bottom of the I-beam are tapered. Closer to the web, they’re thicker, and they become thinner toward the outside edge of the flange. Beyond that tapering the I-beam and H-beam might appear identical.

The I-beam is the most versatile of the three due to the balance and weight of the beam and they are lighter, easier to work with, and have high tensile strength. You’re likely to see the I-beam in various structural applications, especially those that don’t require long spans.

Characteristics of the H-Beam

As previously mentioned, the H-beam and I-beam might appear identical at first glance. They both have flanges connected to the center web that create the appearance of an I or an H. The difference with the H-beam is in the thickness of the flanges.

Where the I-beam flanges are tapered, the H-beam flanges are not. Instead, they maintain the same thickness from the inside of the flange to the outside. The flanges may also be wider than I-beams. That additional width, plus flanges of equal thickness, means uses for the H-beam are a little different.

These are still a popular choice for a variety of construction projects, as the design of the beam makes it more resistant to twisting and shearing forces. These are the beams you might choose for long spans and heavy loads, such as bridge construction, or other structures where heavy loads and stability are critical.

Characteristics of the W-Beam

Another name for the W-beam is the wide-flange beam, which gives you an immediate idea of what’s different with this type of beam. While it still resembles the I-beam and H-beam at first glance, further inspection shows the flanges on the W-beam are longer, or wider. There’s often beveling between the flange and web for additional strength and durability.

The strength and enhanced load-bearing capacity of the W-beam are great for residential and light commercial construction. Some additional light construction, such as smaller bridges, may also be just right for W-beams.
