China High quality astm a36 a283 standard iron carbon steel h-beam

Classification

I-beams are mainly divided into ordinary I-beams, light 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 specifications produced by the former two are No. 10-60, that is, the corresponding height is 10 cm-60 cm. At the same height, the light I-beam has narrow flange, thin web and light weight. The wide-flange I-beam is also called H-beam. The cross section is characterized by two legs parallel and no slope inside the legs. It is an economical 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 I-beams have formed national standards.

Specification

Its specifications are expressed by height × leg thickness × waist thickness, and numbers can also be used to indicate the main dimensions of the specifications. For example, No. 18 I-beam means an I-beam with a height of 18 cm. For I-beams with the same height, you can add the corner code a or b or c after the number to indicate, such as 36a, 36b, 36c, etc. It is divided into ordinary I-beams, light 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 specifications produced by the former two are No. 10-60, that is, the corresponding height is 10 cm-60 cm.

Whether the I-shaped steel is ordinary or light, because the cross-sectional 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 its web plane. components or form them into lattice-type stress-bearing members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which limits its application range. I-beams are widely used in buildings or other metal structures.

Ordinary I-beams and light I-beams have relatively high and narrow cross-section dimensions, so the moments of inertia of the two main sleeves on the cross-section are quite different, which limits their application range. The use of I-beams should be selected according to the requirements of the design drawings.

The selection of I-beams in structural design should be based on its mechanical properties, chemical properties, weldability, structural dimensions, etc. to select reasonable I-beams for use.
