The inner and outer sides of the flange of A36 carbon steel H-beams are parallel or nearly parallel, and the ends of the flange are at right angles. Therefore, it is named parallel flange I-beam. The thickness of the H-beam steel is smaller than that of ordinary I-beams with the same web height, and the flange width is larger than that of ordinary I-beams with the same web thickness. Therefore, it is also called wide-beam I-beam. Determined by the shape, the section modulus, moment of inertia and corresponding strength of the H-beam steel are obviously better than those of ordinary I-beams with the same single weight. A36 steel H-beams properties: A36 H-beam steel is used in metal structures with different requirements. It shows its performance whether it is subjected to bending moments, pressure loads, or eccentric loads. It can greatly improve the carrying capacity compared to ordinary I-beams, saving 10% to 40% of the metal. H-beam 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 inside and outside of the flange are parallel and the edges are at right angles, it is easy to assemble and combine into various components, which can save about 25% of the welding and riveting workload, which can greatly speed up the construction of the project and shorten the construction period.
