H-beams can be produced by either welding or rolling. Welding H-beams involves cutting a strip of suitable thickness to a suitable width, and welding the flange and web together in a continuous welding unit. In modern steel rolling production, H-beams are rolled using a universal mill. The web of the H-beam is rolled between the upper and lower horizontal rolls, and the flange is rolled simultaneously between the side of the horizontal roll and the vertical roll.

By rolling H-beam with a universal mill, the cross section of the rolling piece can be extended more evenly, and the speed difference between the inner and outer rolls of the flange is small, which can reduce the internal stress and shape defects of the product. Appropriately changing the reduction amount of the horizontal roll and the vertical roll of the universal mill can obtain H-beam of different specifications. The roll shape of the universal mill is simple in shape and has a long life, and the consumption of the roll can be greatly reduced. The biggest advantage of rolling H-beam with a universal mill is that only the thickness of the web and flange varies in the same size series, and the size of the rest is fixed. Therefore, the same series of H-beam rolled with universal pass has a variety of web and flange thickness specifications, which greatly increases the number of H-beam specifications and brings great convenience for users to choose the appropriate size specifications.
