DOM tubing (Drawn Over Mandrel) is a high-strength steel tube manufactured using a specific cold-drawing process. It refines pre-existing electric resistance welded (ERW) tubing by pulling it through a die and over a mandrel, resulting in precise dimensions, smooth surfaces, and enhanced mechanical properties.
Introduction to DOM tube
Advantages of DOM tubing
DOM steel tube is the material of choice for demanding internal pressure, rotational, or cyclical-workload applications:
Roll cages, bushings, suspension components, steering columns, and motorcycle frames.
Preferred due to smooth inner surfaces and high structural integrity.
Industrial machinery parts and fitness equipment like treadmill drums.
