H-shaped steel is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable weight-to-weight ratio. 

It is named because its section is the same as the English letter [H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.

The inner and outer sides of the flange of the H-section steel are parallel or nearly parallel, and the ends of the flange are at right angles, hence the name parallel-edge flange I-beam. The thickness of the H-beam is smaller than that of the common I-beam, and the width of the flange is larger than that of the common I-beam. Therefore, it is named the wide-edge I-beam. Depending on the shape, the section modulus, moment of inertia and corresponding strength of the H-beam are significantly better than those of the same single heavy I-beam. Used in metal structures with different requirements, whether it is subjected to bending moment, pressure load and eccentric load, it shows its superior performance, which can greatly improve the bearing capacity compared with ordinary I-beam and save 10%~40% of metal. H-shaped steel has wide flanges, thin webs, many specifications and flexible use. It can save 15% to 20% of metal in various truss structures. Because the inner and outer edges of the flange are parallel, the edge ends are at right angles, which is convenient for assembling and assembling into various components, thereby saving welding and riveting work by about 25%, which can greatly speed up the construction speed of the project and shorten the construction period.
