The main cause of the spreading of cold bent steel sections, known as profiles, is that compared to hot rolled steel sections, smaller unit mass goes together with higher strength.

Steel section production was started at ISD DUNAFERR in 1964 with the installation of one line for open and one for hollow steel sections.

Currently, the production base of the Profiling Works is provided by 2 production lines for open and 4 production lines for hollow steel sections in three halls equipped with cranes on an area of 15,000 sq. m. Almost 180 thousand tons of steel section can be produced with this capacity.

The companies within ISD DUNAFERR group provide the base material required for steel section production. The self-owned strip slitting line included in the technological process makes the flexible serving of production lines possible for 75% of the total base material to be processed.

Besides the open and hollow steel section products for general purpose and for steel structures, many types of steel sections for individual usage are currently included in the product range for peculiar customer demands.

The principle of cold bent steel section production: open steel section can be produced from steel strips slit to the appropriate length by pairs of rolls assembled in stands installed behind each other, or hollow steel section can be produced by welding the two edges of bent strip to each other by high-frequency induction welding.

In accordance with this the technological process of steel section production can be divided into the following phases:

  • Slitting: production of steel strip slit to the appropriate length from wide strip (75% own, 25% DUTRADE SSC);
  • Coiling: welding of the ends of steel strip coils, coiling to vertical, so-called strip accumulator in favour of continuous production (in the case of hollow steel sections);
  • Forming: going through 7-9 stands, the steel strip is given the required shape as an effect of the shaped rolls in the stands;
  • High frequency welding: in the case of hollow steel section production, welding of the two edges of bent strip by high-frequency induction welding;
  • Sizing: hollow steel sections are given the final shape and size on 4-5 stands;
  • Cutting: to 5-12 m thread length by high-speed gin-saw;
  • Finishing: steel section threads are bundled and given identification.
