The difference between I-beam and H-beam

As the name suggests, the I-beam is an "I"-shaped cross-section steel. The inner surfaces of the upper and lower flanges have an inclination, usually 1:6, which makes the flanges thin on the outside and thick on the inside. This causes the I-beam to be in two places. The cross-sectional properties of the main planes vary greatly, making it difficult to exert the same strength properties in applications. Although thickened I-beams have also appeared on the I-beam market, the structure of the I-beam has determined its shortcomings in torsional resistance.

H-beam is a widely used profile in steel structure buildings today. It has many differences compared with I-beam. The first is the flange, and secondly the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The cross-sectional properties of H-shaped steel are significantly better than traditional I-beam, channel steel and angle steel. H-shaped steel is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". The two outer edges of the H-shaped steel have no slope on the inner side and are straight. This makes the welding and splicing of H-beams easier to operate than I-beams, has better mechanical properties per unit weight, and can save a lot of materials and construction time.
