Characteristics of H-shaped steel beams

The inner and outer sides of the H-shaped steel flange are parallel or nearly parallel, and the flange ends are at right angles, hence the name parallel flange I-beam. The web thickness of H-beam is smaller than that of ordinary I-beam with the same height as the web, and the flange width is larger than that of ordinary I-beam with the same height as the web, hence it is also named wide flange I-beam. Determined by its shape, the cross-sectional modulus, moment of inertia, and corresponding strength of H-beams are significantly superior to ordinary I-beams of the same unit weight. When used in metal structures with different requirements, it exhibits superior performance in terms of bearing bending moment, pressure load, and eccentric load. It can greatly improve the bearing capacity compared to ordinary I-beams, saving 10% to 40% of the metal. The H-shaped steel has a wide flange, thin web, multiple specifications, and flexible use. When used in various truss structures, it can save 15% to 20% of metal. Due to the parallel inner and outer sides of its wing edges and the right angle of the edge ends, it is easy to assemble and assemble various components, which can save about 25% of the welding and riveting workload, greatly accelerate the construction speed of the project, and shorten the construction period.
