Application characteristics of I-beam

　　I-beam, also called steel beam, is a long steel bar with an I-shaped cross-section. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d). For example, "Working 160*88*6" means that the waist height is 160 mm, the leg width is 88 mm, and the waist thickness is 6mm I-beam. The specifications of the I-beam can also be expressed by the model number, which indicates the waist height in centimeters, such as I-16#. If I-beams with the same waist height have several different leg widths and waist thicknesses, you need to add a b c to the right of the model number to distinguish them, such as 32a# 32b# 32c#, etc. I-beams are divided into ordinary I-beams and light I-beams. The specification of hot-rolled ordinary I-beams is 10-63#. The specifications of hot-rolled ordinary I-beams supplied by agreement between the supply and demand parties are 12-55#. I-beams are widely used in various building structures, bridges, vehicles, supports, machinery, etc.
