Characteristics of H-beam

Characteristics of H-beam

      The inner and outer sides of the flange of H-shaped steel are parallel or close to parallel, and the end of the flange is at right angles. Therefore, it is named 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, so it is also named wide edge I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in terms of bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by 10% ~ 40%. H-section steel has wide flange, thin web, many specifications and flexible use. It can save metal by 15% ~ 20% when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about 25% of the workload of welding and riveting, greatly speed up the construction speed of the project and shorten the construction period.
