I-beam, also known as steel beam, is a long strip of steel with a cross-section of I-shaped. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as "work 160*88*6 ", which means I-beam with a waist height of 160 mm, a leg width of 88 mm and a waist thickness of 6 mm. The specifications of I-beam can also be expressed by model. The model number indicates the number of centimeters of waist height. For example, 16#, I-beam with the same waist height.
First, the scope of application
Ordinary I-steel, light I-beam, because the cross-sectional dimensions are relatively high and narrow, so the difference of the moment of inertia of the two main sleeves of the section is large, which makes it have great limitations in the application range. The use of I-beams should be selected in accordance with the requirements of the design drawings.
Second, the advantages of I-beam
1. I-beam can be designed to be strong, I-beam is easy to cut and weld, and the length of I-beam can be adjusted according to your own needs.
2. Beautiful appearance. From the appearance of the I-beam, the upper and lower sides are symmetrical. Since ancient times, the symmetry has been emphasized. Therefore, the I-beam is in line with the aesthetics of many people.
3. I-beam is resistant to aging and has a long service life. The raw material of I-beam is the main steel, and its impact resistance and wear resistance are stronger than other materials, so its service life is longer.
4. Light weight, convenient and quick construction. Due to its special structure, the I-beam is lighter in weight with the strength and load-bearing capacity of other profiles. During construction, handling is lighter and helps save time.
5. In addition, I-beam also has the characteristics of insulation, good magnetic permeability, fire retardant, insulation and heat insulation.
