Q235B Structural Galvanized Steel I Beams.I steel beams, also known as steel beam (Universal Beam), is a long strip of steel with an I-shaped cross-section. I-beams are divided into ordinary I-beams and light I-beams. It is a section steel with an I-shaped section. I-beams are mainly divided into ordinary I-beams, light-duty I-beams and wide-flange I-beams. According to the height ratio of flange and web, it is divided into wide, medium and narrow wide flange I-beams. The first two are produced in size 10-60, that is, the corresponding height is 10 cm-60 cm. Lightweight I-beams have narrow flanges, thin webs and light weight for the same height. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no slope on the inside of the legs.
