H-beam, also known as steel beam (H Beam), is a long steel strip with an H-shaped cross section. H-beams are divided into three types: ordinary I-beams, light I-beams, and H-shaped steels. I-beams are widely used in various building structures, bridges, vehicles, brackets, machinery, etc.
The flanges of ordinary I-beams and light I-beams gradually become thinner from the root to the edge, with a certain angle. The models of ordinary I-beams and light I-beams are represented by Arabic numerals of their waist height in centimeters.

The web, flange thickness and flange width are different.
Their specifications are represented by waist height (h) × leg width (b) × waist thickness (d) in millimeters, such as "ordinary I-beam 160×88×6", which means ordinary I-beams with a waist height of 160 mm, a leg width of 88 mm, and a waist thickness of 6 mm. / "Light I-beam 160×81×5", which means light I-beams with a waist height of 160 mm, a leg width of 81 mm, and a waist thickness of 5 mm.

The specifications of ordinary I-beams can also be expressed by model numbers, which indicate the waist height in centimeters, such as general I-beam 16#. If I-beams with the same waist height have several different leg widths and waist thicknesses, a b c should be added to the right of the model number to distinguish them, such as general I-beam 32#a, 32#b, 32#c, etc. The specifications of hot-rolled ordinary I-beams are 10-63#. The specifications of hot-rolled ordinary I-beams supplied by agreement between the supply and demand parties are 12-55#.
