The flanges of H-beams are parallel or nearly parallel on both sides, with the flange ends forming right angles, hence the name "Parallel Flange Beam." The web thickness of H-beams is thinner than that of a standard I-beam of the same height, while the flange width is wider, leading to the alternate name "Wide Flange Beam." Due to its shape, H-beams have significantly higher section modulus, moment of inertia, and strength compared to standard I-beams of the same weight. Used in various metal structures, they demonstrate superior performance in withstanding bending moments, compressive loads, and eccentric loads, greatly enhancing load-bearing capacity and saving 10% to 40% of metal compared to standard I-beams. H-beams, with their wide flanges, thin webs, numerous sizes, and flexible use, can save 15% to 20% of metal in various truss structures. Their parallel flanges and right-angled ends facilitate assembly and combination into various components, saving approximately 25% of welding and riveting work, significantly speeding up construction and shortening project timelines.
