Our selection of steel beams, also called structural steel beams or steel support beams, comes in a variety of sizes and weights. An I beam is very similar to an H beam, which can be somewhat confusing. You'll find examples of both types of beam here in this category. An H beam is generally heavier than an I beam. Both have two dimensions: the width, known as the flange, and the height, known as the web. The main difference between the two is that the H beam has wider flanges than the I beam, and the I beam has tapered edges. In an I beam, the height (web) is greater than the width (flange). This is the opposite with H beams.
You may also see S beam and W beam designations referring to steel beams. The W designates wide flange beam, which is probably also an H beam (more confusion). The S in S beams signifies tapered flanges, which purportedly offer greater strength than is found in H beams.
