What is I-beam?

I-beam steel, also known as steel beam, is a long strip of steel with an I-shaped cross section. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as "work 160 * 88 * 6", which means that the waist height is 160 mm, the leg width is 88 mm, and the waist thickness is 6 mm. I-beams are divided into three types: ordinary I-beams, light I-beams and H-beams.

The flange of ordinary I-beam steel and light I-shaped steel gradually becomes thinner from the root to the edge, and has a certain angle. Because of their relatively high and narrow cross-sectional dimensions, the moment of inertia of the two main sleeves of the cross-section is quite different. . It is not used for axial compression members or members that are perpendicular to the web plane and have bending members, which has a great limitation in its application range.

I-beam steel is widely used in various building structures, bridges, vehicles, brackets, machinery, etc.
