The inner and outer sides of the flange of the H-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of the H-shaped steel is smaller than that of the ordinary I-beam with the same height of the web, and the width of the flange is larger than that of the ordinary I-beam with the same height of the web, so it is also called wide-edge I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beams are significantly better than ordinary I-beams of the same single weight. Used in metal structures with different requirements, whether it bears bending moment, pressure load, or eccentric load, it shows its superior performance. Compared with ordinary I-beams, it can greatly improve the bearing capacity and save 10% to 40% of metal. H-shaped steel has wide flanges, thin webs, multiple specifications, and flexible use. It can save 15% to 20% of metal in various truss structures. Because the inner and outer sides of the flanges are parallel and the edges are at right angles, it is easy to assemble and combine into various components, thereby saving about 25% of the welding and riveting workload, which can greatly speed up the construction speed of the project and shorten the construction period.
