chemicals used in steel mills

  • Material selection and product

    Steel material is supplied in two product forms – 'flat products' (steel plate and strip) and 'long products' (rolled sections, either open beams, angles, etc or hollow sections). For structural use in bridges these products are inevitably cut (to size and shape) and welded, one component to another.In the structure, the material is subject to tensile and compressive forces.
