I-steel, also known as steel beam, is a long steel bar having an i-shaped cross section. The I-beams are mainly divided into common I-beams, light I-beams and wide-flange I-beams. The wide-flange I-steel is divided into wide-flange I-steel, medium-flange I-steel and narrow-flange I-steel according to the height ratio of the flange to the web. The former two are produced in a specification of 10-60, i.e. the corresponding height is 10-60 cm. Under the same height, the light I-steel has narrow flange, thin web and light weight.
