Drawn Over Mandrel (DOM) Steel Round Tube

Drawn Over Mandrel (DOM) Steel Round Tube

DOM Steel Round Tube is a high-quality, cold-drawn tube made from steel that is drawn over a mandrel and through a die to achieve precise dimensions and an excellent surface finish. This manufacturing process results in a seamless, uniform tube with superior mechanical properties, making it ideal for applications requiring strength, accuracy, and reliability, such as in hydraulic components, automotive parts, and general fabrication.
