What is the difference between I-beam and H-beam?

Many people think that I-beams are called domestically and H-beams are called foreignly. In fact, this understanding is wrong. H-beam and I-beam are different in shape


As the name suggests, the I-beam is a type of “I” -shaped cross-section. The inner surface of the upper and lower flanges has a slope, generally 1: 6, which makes the flanges thin and thick on the outside. The cross-section characteristics of the main plane are very different, and it is difficult to exert the strength characteristics just now in applications. Although thicker I-beams have also appeared on the I-beam market, the structure of the I-beams has already determined their torsional shortcomings.

　H-section steel is a widely used section in today's steel structure buildings. It has many differences compared to I-beams. The first is the flange, and the second is that the inner surface of the flange is not inclined, and the upper and lower surfaces are parallel. The cross-section characteristics of H-beams are significantly better than traditional I-beams, channel steels and angle steels. Metal processing WeChat, the content is good, worthy of attention. H-shaped steel is an economical section and high-efficiency profile with a more optimized cross-sectional area allocation and a more reasonable weight-to-weight ratio. The inner sides of the two outer edges of the H-shaped steel are straight and have no slope. This makes H-beam welding and splicing simpler than I-beam operation and better mechanical properties per unit weight, which can save a lot of material and construction time.
