  • Galvanized coil is produced by continuous hot-dip galvanizing process using hot-rolled steel strip or cold-rolled steel strip as substrate. Hot-dip galvanized sheets are supplied in rectangular flat sheets after cross-cutting; hot-dip galvanized coils are supplied in coils after coiling. Hot-dip gal
  • There are four forms of h-beam specifications.
    1. According to the width of the product flange, it is divided into wide flange, middle flange and narrow flange H-beam. The flange width b of the wide flange and middle flange H-section steel is greater than or equal to the web height H, and the flange width b of the narrow flange H-section steel is about half of the web height H.
    2. According to the use of the product, it can be divided into H-shaped steel beam, H-shaped steel column, H-shaped steel pile, H-shaped steel flange extra-thick beam. Sometimes parallel leg channels and parallel flange T-beams are also included in the scope of H-beams. Beam materials generally use narrow flange H-beams, and column materials generally use wide-flange H-beams.
    3. According to the production method, it can be divided into welded H-beam and rolled H-beam.
    4. According to the specifications and sizes, it is divided into large, medium and small H-beams. Generally speaking, products with web hei

  • Production MethodsEdit BroadcastH-beam steel can be produced by welding or rolling. Welded H-beam is to cut strip of suitable thickness to suitable width, and weld the flange and web together on a continuous welding unit. Welded H-beam has the disadvantages of large metal consumption, difficult to e
