Classification

I-beams are mainly divided into ordinary I-beams, light-duty I-beams and wide-flange I-beams. According to the height ratio of the flange to the web, it is divided into wide, medium, and narrow wide flange I-beams. The first two production specifications are 10-60, that is, the corresponding height is 10 cm-60 cm. At the same height, the lightweight I-beam has narrow flanges, thin webs and light weight. The wide-flange I-beam is also called H-beam, and its cross-section is characterized by parallel legs and no slope on the inner side of the legs. It belongs to economic section steel, which is rolled on a four-high universal rolling mill, so it is also called “universal I-beam”. Ordinary I-beams and light-duty I-beams have become national standards.

Application characteristics

Regardless of whether the I-shaped steel is ordinary or light, because the cross-section size is relatively high and narrow, the moment of inertia of the two main axes of the cross-section is quite different, so it can only be directly used for bending in the plane of its web. Components or form them into lattice-type force-bearing components. It is not suitable to use axial compression components or components that are perpendicular to the plane of the web, which is also curved, which makes its application scope very limited. I-beams are widely used in construction or other metal structures.
Ordinary I-beams and light-duty I-beams have relatively high and narrow cross-sections, so the moments of inertia of the two main axes of the cross-sections are quite different, which limits their application scope. The use of I-beam should be selected according to the requirements of the design drawings.
The selection of I-beam in the structural design should be based on its mechanical properties, chemical properties, weldability, structural size, etc. to select a reasonable I-beam for use.

Scope of application

C-shaped steel is widely used in the purlins and wall beams of steel structure buildings, and can also be assembled into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.
