What are the characteristics of H-section steel

H-section steel is an economic section steel with section shape similar to capital Latin letter H. It is also called universal steel beam, wide edge (side) I-section steel or parallel flange I-section steel. The cross section of H-section steel usually consists of web and flange plate, also known as waist and edge.

The inner and outer sides of the flange of H-section steel are parallel or close to parallel, and the flange ends are at right angles, so it is named parallel flange I-section steel. The web thickness of H-section steel is smaller than that of common I-section steel with the same height of web, and the flange width is larger than that of common I-section steel with the same height of web, so it is also called wide edge I-section steel.

Determined by the shape, the section modulus, the moment of inertia and the corresponding strength of H-section steel are obviously superior to the common I-section steel of the same single weight. It can be used in metal structures with different requirements, whether it bears bending moment, pressure load or eccentric load, which shows its superior performance.

Compared with ordinary I-section steel, H-section steel can greatly improve the bearing capacity and save 10% - 40% of metal. H-section steel has wide flange, thin web, many specifications and flexible use. It can save 15% - 20% metal in various truss structures. Because the inner and outer sides of the flange are parallel and the flange ends are at right angles, it is convenient to assemble various components, thus saving about 25% of the welding and riveting work, greatly speeding up the construction speed of the project and shortening the construction period.
