Often someone will ask the flame xinsenyu i-beam and H beam in the end what difference ah, how to distinguish between the two?Some people will think I beam and H beam is the same thing, in fact, this understanding is wrong, small make up here for you to do a detailed solution, we will guess the following two pictures, which is I beam, which H beam?
For familiar friends, it can be seen at a glance that the first picture is i-beam steel and the second picture is h-beam steel. Then, what is the basis of it?The following is a detailed introduction.Introduction to i-steel:I-steel, as its name suggests, is a kind of "I" shaped section steel, the inner surface of the upper and lower flange inclination, generally 1:6, making the flange outside thin and inside thick, so that i-steel in the two main plane section characteristics of a huge difference, in the application of steel strength characteristics, as shown in the first picture.Although I steel market also appeared in the reinforced I steel, but the structure of I steel has decided its torsional performance short board.Introduction to h-beam:H beam is widely used in steel structure building nowadays. It has many differences compared with i-beam.1) flange, the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel.2) the two outer and inner sides of the h-beam have no inclination and are straight.3) the section characteristics of h-beam are significantly better than that of traditional i-beam, channel and Angle steels.Summary: i-steel section under direct pressure is good, tensile resistance, but section size because the wing is too narrow, can not resist torsion.H steel is on the contrary, so both have advantages and disadvantages.
