High Quality Universal Beam

Product Information

I-beams are mainly divided into ordinary I-beams, light I-beams and broad flanged I-beams. According to the flange and web height ratio is divided into wide, medium, narrow flange I-steel. The specifications of the first two are 10-60, that is, the corresponding height is 10-60 cm. At the same height, light I-steel flange, thin web, light weight. Wide flange I-steel also known as H-beam, section characteristics are parallel legs, and there is no inclination inside the leg. It belongs to the economic section steel, is in four high universal rolling mill rolling, so also known as "universal I-steel". Ordinary I-steel, light I-steel has formed the national standard.

Feature

I-shaped steel, whether ordinary or light, due to the relatively high section size and narrow, the moment of inertia difference between the two spindles on the section is large, so it can only be directly used in its web plane bending members or the composition of lattice structural members. It is not suitable for axial compression members or bending members perpendicular to the web plane, which makes its application scope very limited. I-beams are widely used in construction and other metal structures.

Ordinary I-steel, light I-steel, due to the section size is relatively high, relatively narrow, so the moment of inertia of the two spindles on the section is relatively large difference, which makes it has a very limited application range. I-beams shall be selected according to the requirements of the design drawings.

In structural design, I-beams should be selected according to their mechanical properties, chemical properties, weldable properties, structural size and other reasonable choice of I-beams for use.
