H-section steel is a kind of economic section of high efficiency with more optimized section area distribution and more reasonable strength-to-weight ratio. Because its section is the same as the English letter "H", it gets its name. Because each part of H-beam is arranged at right angles, h-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.

An economic section shaped like the capital Latin letter H, also known as universal steel beam, wide flange (edge) I-beams or parallel flange I-beams. The cross-section of H-beams usually includes two parts, the web and the flange, also known as the waist and the edge. The inner and outer flanges of H-beams are parallel or nearly parallel, and the flanges end at right angles, hence the name parallel flanged I-beams. 

The web thickness of H-shaped steel is smaller than that of ordinary I-steel with the same high web, and the flange width is larger than that of ordinary I-steel with the same high web, so it is also named wide flange I-steel. Determined by the shape, the section modulus,moment of inertia and corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight.

H beam is a kind of economic section of high efficiency with more optimized section area distribution and more reasonable strength-to-weight ratio. Because its section is the same as the English letter "H", it gets its name. Because each part of h-beam is arranged at right angles, h-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions. Its materials are Q235B,SM490, SS400, Q345B and so on.

I-beam is also called H steel beam and is a long strip of steel with a cross-section of I-shaped. I-shaped steel is divided into hot-rolled I-beam and light I-beam. Is a section steel with a cross-sectional shape

H section steel is a more optimized section area allocation, more reasonable strength to weight ratio of economic section high efficiency profiles, because of its section and the English letter "H" the same name. Because each part of H-beam is arranged at

right angles, h-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.
