H Beams are commonly used in the construction of buildings as well but also large trailers and bridges, among others.

Due to their slightly different cross-section shape, thicker central web and wider flanges, H beams can bear larger loads than I beams. While both are advantageous load-bearing structures, due to how long H beams can span for, they are more reliable for larger-scale projects. However, I beams are lighter and still have proven highly effective in numerous applications.
