H-Beam

H-shaped steel is an economical cross-section high-efficiency section with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.
H-shaped steel is a widely used profile in steel structure buildings today, and it has many differences compared with I-shaped steel. The first is the flange, and second, the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The cross-sectional properties of H-beams are significantly better than traditional I-beams, channel steels and angle steels.
The two outer and inner sides of the H-shaped steel have no slope and are straight. This makes the welding and splicing of H-beams easier than I-beams, and has better mechanical properties per unit weight, which can save a lot of materials and construction time. The section of the I-Beam is well subjected to vertical pressure and resistant to tension, but the section size cannot resist torsion because the wing plate is too narrow. H steel is the opposite, both have their own advantages and disadvantages.
