Precision Chromoly DOM Tubing for Racing, Off-road, and Performance Applications
Consistent Wall Thickness | Superior Strength | Excellent Concentricity | Precision Fit
What Is DOM Tubing?
DOM (Drawn Over Mandrel) Tubing refers to steel tubes produced through a precision cold-drawing process over a mandrel.This method eliminates weld flash and refines the inner and outer surfaces, resulting in smooth finish, uniform wall thickness, and exceptional dimensional accuracy.
While standard DOM tubes can be made from carbon steel (such as 1020 or 1026), our production focuses on high-performance 4130 Chromoly DOM Tubing — a material known for its lightweight structure, high tensile strength, and excellent fatigue resistance.
Unlike regular carbon DOM tubes, our Chromoly DOM tubing offers superior tensile strength, fatigue resistance, and weight savings — making it the ideal choice for racing chassis, off-road roll cages, and other performance-critical structures.
Why Chromoly DOM Tubing ?
Key Advantages of Chromoly DOM Tubing
- High Tensile & Yield Strength – Withstands demanding loads and structural stress.
- Lightweight but Strong – Provides a better strength-to-weight ratio than carbon steel DOM.
- Excellent Weldability & Ductility – Suitable for precision welding, bending, and forming.
- Superior Fatigue & Impact Resistance – Maintains integrity under repeated stress and impact.
| Feature | Carbon DOM | Chromoly DOM |
|---|---|---|
| Strength | Standard | Up to 2× higher tensile strength |
| Weight | Heavier | Lighter with same or higher strength |
| Fatigue Resistance | Moderate | Excellent |
| Application | General mechanical use | Racing / Off-road / Performance builds |
