H-beam is an economical cross-sectional profile with optimized cross-sectional area distribution and a more reasonable strength to weight ratio, named after its cross-section that is the same as the English letter "H". Due to the fact that various parts of H-beams are arranged at right angles, H-beams have the advantages of strong bending resistance, simple construction, cost savings, and lightweight structure in all directions. They have been widely used as an economical cross-sectional profile with a cross-sectional shape similar to the capital Latin letter H, also known as steel beams, wide (edge) I-beams, or parallel flange I-beams. The cross-section of H-beam usually includes two parts: the web plate and the flange plate, also known as the waist and edge.
