H Beam

The inner and outer flanges of H-shaped steel are parallel or nearly parallel, and the ends of the flanges are at right angles. Therefore, it is called parallel flange I-beam. The web thickness of H-shaped steel is smaller than that of ordinary I-beams with the same web height, while the flange width is larger. Therefore, it is also called wide flange I-beam. Determined by its shape, the section modulus, moment of inertia and corresponding strength of H-shaped steel are significantly superior to those of ordinary I-beams of the same single weight. When used in metal structures with different requirements, it demonstrates superior performance in withstanding bending moments, pressure loads, and eccentric loads. Compared with ordinary I-beams, it can significantly enhance the load-bearing capacity and save 10% to 40% of metal. H-shaped steel features wide flanges, thin webs, a wide range of specifications and flexible application. When used in various truss structures, it can save 15% to 20% of metal. Due to the parallel inner and outer sides of its flanges and the right-angle ends of the flanges, it is convenient to assemble and combine into various components, thereby saving about 25% of the welding and riveting workload, which can greatly accelerate the construction speed of the project and shorten the construction period.
