The process of cold drawing steel is a procedure by which metal is formed in order to achieve complex profile cross sections of excellent precision. After careful pre-treatment and descaling 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 steel and hot extruded special profiles tightens the cross-sectional tolerances, thus leading to significant improvement in dimensional accuracy and surface quality. Cold drawn special profiles offer the same precision achieved by machining - but without the waste.

smooth and scale-free surface
sharp edges
uninterrupted grain orientation
increased tensile strength and yield point
