The difference between I-beams and H-beams
In the construction industry, steel is often used, such as I-beams and H-beams.
I-steel is mainly divided into ordinary I-steel, light I-steel and wide flange I-steel. According to the height ratio of flange and web, it is divided into wide, medium and narrow wide flange I-beams. The specifications of the first two are 10-60, that is, the corresponding height is 10-60cm.
At the same height, the light I-beam flange is narrow, the web is thin, and the weight is light. Wide flange I-beams, also known as H-beams, are characterized by parallel legs and no inclination inside legs. It is an economic section steel and is rolled on a four-high mill. Ordinary I-beams and light I-beams have formed standards.
I-steel, as the name indicates, is a "work" type section steel, upper and lower flange inner surface inclination, generally 1:6, making the flange thin outside and thick inside, so the cross-section characteristics of I-steel in the two main planes are huge difference, it is difficult to play the strength characteristics of steel in the application. Although there are also thickened I-beams in the market, the structure of I-beams has determined its torsional performance.
When choosing steel, pay attention to the structural part of steel, be sure to pay attention to the fact that there are many types of steel, when choosing steel, you can choose the right quality of steel according to your actual situation.
When choosing steel, it is necessary to make a certain judgment for the structural environment, working at low temperature, welding structure, you can choose some anti-low temperature sedative steel, this steel is subjected to low temperature, there will be no deformation phenomenon, but not because of some environmental problems lead to steel corrosion.
You can choose high temperature resistant steel, because this steel can resist a certain high temperature in the middle, and will not make the steel in a deformation or corrosion phenomenon in a high temperature environment.
