Beam I-beam steel welded wide-shelf. Ust-Kamenogorsk

Production of a wide-shelf beam An I-beam wide-shelf (marked with Ш) has a section in the form of the letter H and a ratio of height to width of the flange 1:2.5-1:1.16. Such beams are stable and do not require additional fasteners during installation. Depending on the composition of the alloy, the beams can be operated at temperatures ranging from -70 to +425 degrees. For the manufacture of an I-beam wide-shelf beam, a thick hot-rolled sheet of low-alloy or carbon steel is taken as a raw material, if necessary, it is straightened, cut into strips, and the edges are cleaned. Welded wide-shelf beams are assembled from three elements - 2 shelves and walls: on an automated mill - on an industrial scale. The wall and shelves are mutually perpendicular and symmetrical. on the rack - for piece production to order. With the help of an inclined electrode of the tees, the beams are welded on both sides of the wall at the same time, stiffeners are installed and welded semi-automatically or manually. After welding, the shelves of the product are corrected from mushrooming and an anti-corrosion coating is applied. I-beam wide-shelf: split - covers 1 span and has 2 support points, continuous - covers several spans and has > 2 support points. The profile wall of a wide-shelf welded beam can be through: with holes, cutouts, perforations. This increases the bearing capacity of the product.
