Generally, Steel I beams and H beams are widely used in residential or big construction project. high-strength, long-span structural timber beams which are extensively used in construction and engineering projects. In general speaking, I beams contains S-beam, universal beam, H beam or wide flange beam. However, these beam sections are different in dimensions, strength and applications. I beam consists horizontal element - flanges and vertical element - web. The web resists shear forces while the flanges resist most of the bending moment. Due to its effectiveness in carrying both bending and shear loads, it is the most frequent for steel buildings, bridge and civil project.
