The most common steel beam is the I-beam. The beam is composed of two horizontal flat surfaces called flanges connected by a horizontal component called a web.

The cross section is similar in form to a capital letter I with the serifs, hence, the name I-beam. When turned on its side, the beam will resemble the form of a capital letter H which is why it is also called an H-beam.

I-beams are commonly made of structural steel but may also be formed from aluminium or other materials.
