Cold drawn bars are high-precision steel products obtained by shaping hot rolled steel bars at room temperature through special drawing processes. This method improves surface quality, tightens dimensional tolerances and enhances mechanical properties.
During cold drawing, the strength and hardness of the material increase while high precision is achieved in diameter and cross-section. Thanks to these properties, cold drawn bars are preferred in automotive, machine building, hydraulic and pneumatic systems, fasteners, the die and mould industry, defence and precision engineering applications.
Produced in round, square, hexagonal and special sections, cold drawn bars improve efficiency in machining thanks to their superior surface quality and high dimensional accuracy. They offer important advantages such as low surface roughness, shorter machining times and lower tool wear.
Mechanical tests, dimensional checks and surface quality inspections are carried out during production to ensure compliance with national and international standards. For applications requiring high strength, excellent surface quality and tight tolerances, cold drawn bars offer a reliable and economical solution.
