H steel is a kind of economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength weight ratio, which is named because its cross-section is the same as the English letter "H". Because all parts of H-section steel are arranged at right angles,
H-section steel has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, and has been widely used in many different industry.
The inner and outer sides of the flange of H steel are parallel or close to parallel, and the end of the flange is at right angles, so it is named parallel flange I-steel. The web thickness of H-beam is smaller than that of ordinary I-beam with the same height of the web, and the flange width is larger than that of ordinary I-beam with the same height of 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 significantly 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%. The flange of H steel is wide, the web is thin, there are many specifications, and the use is flexible.
When used in various truss structures, it can save 15% - 20% of metal. 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 assemble into 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.
