H section steel/H beam is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its section is the same as the English letter "H". Since the various 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 structure weight in all directions, and has been widely used.
        H-beam steel is widely used for: various civil and industrial building structures; large- span industrial plants and modern high-rise buildings, especially industrial plants with frequent seismic activities and high-temperature working conditions; heavy equipment; highways; . ship skeletons; mine supports; foundation treatment and embankment engineering; various mechanical components. 
        H beam can greatly improve the load-bearing capacity and save metal by 10%-40%. H-shaped steel has wide flanges, thin webs, multiple specifications, and flexible use. It can save 15% to 20% of metal when used in various truss structures. Because the flanges are parallel inside and outside, and the edges are at right angles, it is easy to assemble and assemble various components, which can save about 25% of the welding and riveting workload, which can greatly accelerate the construction speed of the project and shorten the construction period.
