H-beam is a kind of economic sectional steel, whose section area distribution is more optimized, the strength-to-weight ratio is more reasonable, and the mechanical properties of the section are better. It is designed based on the optimization of I-section steel of the best section mechanical properties of economic sectional steel, because its section is the same as the English letter “H”, so it can be called H-Beam. Because the different part of the X-beam is arranged at right angles, the X-beam has the advantages of strong bending resistance, simple structure, cost saving and light structural weight in all directions, so it has been widely used.
H-beam as a new type of economical construction steel. The section shape of X-beam steel is economical and reasonable, the mechanical properties are good, and the elongation of each point on the section is uniform and the internal stress is small. Compared with ordinary I-beam steel, it has the advantages of larger section modulus, lighter weight and more saving metal, which can reduce the building structure by 30-40%. And because its inner and outer legs are parallel, the leg’s rectangular end, assembled into components, can save welding and riveting workload up to 25%. It is often used in large buildings (such as workshops, high-rise buildings, etc.), as well as bridges, ships, material handling equipment, equipment foundation, piers, foundation piles, etc.
