Special profiles are basically sections with a shape or set of properties that differ from those of general-use, universal rolled steel. Special profiles are used for specific operating conditions, which, in fact, determine their design, as well as physical and mechanical properties. Special metal profiles are manufactured from carbon, alloyed and stainless steels, aluminium, copper and other non- ferrous metals and alloys.

Special steel profiles are also extensively used in the construction (sheet piles and I-beams, unequal channels and other profiles), automotive (strip for caterpillar chains, truck wheel rims) and other industries.

Manufacture of special steel profiles

Special profiles are manufactured by section or specialised mills using hot or cold rolling as a process.

The main rolling processes include:

  • Longitudinal rolling on light to medium and heavy section rolling mills is used for most steel sections and shapes. During the longitudinal rolling, the rolls rotate in various directions, take in the feedstock, deform it and transfer in the direction transverse to their axles. This is the process used to manufacture rails, Z-profiles, bulb flats, pit props, round profiles for mill rods, steel for elevator guide rails and other types of special profiles.
     
  • Transverse rolling is used to manufacture special profiles that, due to their shape, are solids of revolution (balls, axles, pinions, shafts, etc). During the transverse rolling, the rolls rotate in the same direction to rotate the feedstock and then deform it in the transverse direction. Reducing the feedstock head and forming it to the required cross-sectional shape is possible by profiling rolls and changing the roll gap.

Also, some types of special profiles (Z-type equal and unequal profiles, С-profiles, U-profiles and other profiles) can be manufactured by profiling the strip on roll- forming machines. In this case, the production process implies sequentially profiling steel sheets by rollers and rolls without changing the strip thickness. This makes it possible to manufacture shaped products by balancing metal distribution across its cross-section and reducing the loss of metal, which, in turn, helps to reduce the cost of downstream processing and manufacture of new goods.
 

Buy special profiles from the manufacturer

Enterprises of Metinvest Group produce a wide range of special profiles for the mining and steel industry, construction, and general and special-use machine building.
