Multipurpose Low-Carbon Steel Round Tubes
 |
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit.
Stress-Relieved Heat Treatment—Tubes that are stress relieved minimize warping during machining.
DOM—DOM (drawn over mandrel) welded tubes are stronger than ERW (electric resistance welded) tubes.
