Special cold-drawn steel tubes are engineering products manufactured by cold drawing to achieve high precision, superior surface quality and improved mechanical properties. In this process, hot rolled or seamless tubes are passed through special dies to bring them to the required diameter, wall thickness and tolerances. The result is tubes with high dimensional accuracy and excellent surface quality.
Cold drawing increases the tubes’ strength, hardness and durability while reducing surface roughness to a minimum. These properties offer significant advantages in applications requiring precision machining. In projects with tight tolerance requirements, they reduce the need for additional machining and help lower production costs.
Special cold-drawn steel tubes are widely used in automotive, hydraulic and pneumatic systems, machine building, energy, defence, agricultural machinery and various industrial applications. They are preferred for cylinder bodies, shaft sleeves, mechanical support systems, precision machine parts and high-performance equipment.
Available in various steel grades, diameters and wall thicknesses, they can also be supplied in custom sizes on request. Chemical analyses, mechanical tests, dimensional measurements and surface quality checks during production ensure compliance with national and international standards.
Offering high precision, superior mechanical performance and excellent surface quality, special cold-drawn steel tubes are among the reliable, long-lasting engineering solutions modern industry needs.
