H steel column is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H steel column are arranged at right angles, the H-beam has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight, and has been widely used. An economical cross-sectional profile with a cross-sectional shape similar to the capital Latin letter H, also known as a universal steel beam, wide flange (edge) I-beam or parallel flange I-beam. The cross-section of the H-beam usually includes two parts: the web and the flange plate, also known as the waist and the edge.
