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.
