H-beam usage

Due to the above advantages, American standard H-beams are widely used in various civil and industrial building structures; Various large-span industrial factories and modern high-rise buildings, especially in areas with frequent seismic activity and under high-temperature working conditions; Large bridges with high load-bearing capacity, good cross-sectional stability, and large spans are required; Heavy equipment; Expressway; Ship skeleton; Mine support; Foundation treatment and embankment engineering; Various machine components.

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.

H-beam is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength to weight ratio, named after the same section as the English letter "H". Due to the fact that all parts of H-beam are arranged at right angles, H-beam has advantages such as strong bending resistance, simple construction, cost savings, and light structural weight in all directions, and has been widely used.
