H-beam in steel structure engineering is a kind of economic section and efficient profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio, named because its section is the same as the letter “H” in English. Since all parts of H-beam are arranged at right angles, H-beam has the advantages of strong bending resistance in all directions, simple construction, cost saving and light weight of structure, etc., and has been widely used.
H-beam is a widely used profile in steel construction today, and it has many differences compared with I-beam. The cross-sectional characteristics of H-beams are significantly better than those of traditional I-beams, channels and angles.
There is no slope on the inside of the two outer edges of H-beams, which are flat and straight. This makes the welding and splicing of H-beam easier than I-beam, and the mechanical properties per unit weight are better, which can save a lot of material and construction time. I-beam cross-section is subjected to good straight pressure and is tensile, but the cross-section size is too narrow due to the wing plate and cannot resist twisting. h-beam is the opposite, both have their advantages and disadvantages.
