Hot Rolling
Duiring the production of special hot rolled steel, profiles by hot rolling the input billet or slab is formed into length up to 70m using two opposite ratating cylindrical tolls. The hot rolled steel shapes of this forming technique are used in a multitude of industrial applications, Hot rolled special profiles offer innovative solutions whether it be for automative,material handing,railroad or thicker flange and web thickness structural steel shapes use. Finished hot rolled steel shapes are roller straightened and sheared into production lengths or swan into fixed lengths according to cutomer wishes.

Cold drawn
The process of cold drawing is a procudure by which steel prfiles are formed in order to achieve complex cross sections of excellent precision in these cold drawn steel shapes. After careful pre-treatment and de-scaling, the special profile bars are drawn through a forming die. This operation can be repeated up to three or four times. Cold drawing of hot rolled and hot extruded special pre-shape steel profiles tightens the cross-sectional tolerences, thus leading to significant improvement in dimensional accuracy and surface quality. Cold drawn steel special profiles offer the same precision achieved by machining but without the waste.
