People often ask what are the differences between I-beam steel and H-beam steel? Some people think that I-beam steel and H-beam steel are the same thing. In fact, this understanding is wrong. Regarding the differences between I-beam steel and H-beam steel, the following will give you a detailed answer.
I-beam steel is a kind of "I"-shaped cross-section steel. The inner surface of the upper and lower flanges has an inclination, generally 1:6, which makes the flange thinner on the outside and thicker on the inside. Therefore, the cross-sectional characteristics of the I-beam steel in the two main planes are greatly different, and it is difficult to use the strength characteristics of steel in applications.
H-beam steel is a widely used profile in today's steel structure construction, and it has many differences compared with I-beam steel. The first is the flange. The inner surface of the flange of the H-beam steel has no inclination, and the upper and lower surfaces are parallel. Secondly, the two outer sides of the H-beam steel have no slope and are straight. Finally, the section properties of H-beam steel are significantly better than traditional I-beams, Channel steels and Angle steels.
In general, the section of I-beam steel is well subjected to direct pressure and is resistant to tension, but the section size is too narrow for the wing plate to resist torsion. The opposite is true for H-beam steel, so both have their own advantages and disadvantages.
