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 the cross-section.
H-beam has wider flanges than I-beam, but I-beam has tapered edges. The width is the flange and the height is the web. The difference between the H and I beams is the flange per band ratio. The H beam tends to be heavier than the I beam, which is why some say it is better than the I beam, but this is subjective, as the H beam is generally heavier.
Since H beams have thicker walls and flanges, they are ideal for mezzanines, platforms, bridges and other common residential and commercial buildings.
Wide flanges are commonly used in residential projects. The internal dimensions of the H-beams are constant, in order to make them the preferred choice of material in the structure of the trailer and truck.
