H beam’s features and application.

H beam is an economic section and efficient profile with more optimized section area distribution and more reasonable strong weight ratio. It is named because its section is the same as the English letter "H". Because all parts of H beam are arranged at right angles, H beam has the advantages of strong bending ability, simple construction, cost saving and light structural weight, and has been widely used.

The inner and outer flange of H beam is parallel or close to parallel, and the end of the flange is right Angle, hence the name parallel flange H beam. The web thickness of H beam is smaller than that of the ordinary H beam with the same high web, and the flange width is larger than the ordinary H beam with the same high web, so the name wide edge H beam. Judging by the shape, the section modulus, inertia moment and corresponding strength of H beam are obviously better than the ordinary H beam with the same single weight. Use in different requirements of the metal structure, whether under the bending moment, pressure load, eccentric load all show its superior performance, can greatly improve the bearing capacity of ordinary H beam, save metal 10%~40%. H beam has wide flange, thin web, many specifications, and is flexible in use, which can save 15%~20% of metal in various truss structures. Because the inner and outer flange is parallel, the edge is a right Angle, which is easy to assemble and combine into various components, thus saving about 25% of welding and riveting work, which can greatly accelerate the construction speed of the project and shorten the construction period.

Due to the above advantages, H beam is widely used, mainly in various civil and industrial building structures; various large span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and high temperature working conditions; large bridge with large bearing capacity, good section stability and large span; heavy equipment; highway; ship skeleton; mine support; foundation treatment and dam engineering; various machine components.
