Steel Beams: How to Choose the Right Fit
Steel beams are often necessary for significant construction or renovation projects. However, there are distinct types, and each of them has pros and cons associated with it. For instance, you may need to choose between I-beams or wide flange beams.
Wide flange steel beams are one common type of steel beam, but it's not uncommon for them to be confused with others. Knowing the differences requires understanding the appropriate terms, such as web and flange. This blog addresses how to choose suitable steel beams in your desired sizes.
What Is a Wide Flange Steel Beam?
Let's define a few words before we understand what to expect from a wide flange beam. Webs are the vertical parts that connect flanges, while flanges are the horizontal sections of a beam.
A steel wide flange beam is shaped like a sideways H. The web may be the same width (or wider) than the flange. It's easy to determine wide flange steel beam dimensions. The depth of the beam is indicated by the first number, while the weight per foot is defined by the second number.
For example, on a W21 x 44 beam, the depth is 20.66", and the flange width is 6.5". Remember that the web bears the shear forces while the flange fights against bending forces.
Many projects require the use of wide flange beams. Some include truck bed frames, support beams for steel factories and buildings, bridges, machinery, and factory platforms.
What Is an I-Beam?
Compared to steel wide flange beams, I-beams have flanges that are often shorter than the webs. This means that when you look at a cross-section of the beam, it looks like a capital I. The design ensures that the beam can bend if there is a lot of pressure. I-beams tend to be limited in options, whereas there are many more lengths and sizes of wide flange beams.
I-beams are used in several types of products, such as support steel channels and angles, truck bed frames, support beams for engineering, construction, and facilities, and factories and warehouses.

Choosing the Right Beam of an Appropriate Size
When choosing suitable beams in an appropriate size, the decision often comes down to your specific needs. An I-beam will have tapered flanges and thinner webs for lightweight construction. It's typically used for spans of 33 to 100 feet. While a wide flange beam is made up of three components, an I-beam is only a single piece of steel.
With a wide flange beam, you'll find a thicker web and wider flange. The design makes them great for heavyweight situations. In addition, they can be used for up to 300 feet, making them more versatile. A bevel is included with the beams to connect the web at the top and bottom. Lightweight wide flange beams are most compatible with residential construction.
