EN10305 Cold Rolled Seamless Steel Tube

Tube rolling is a very precise method of reducing very thin walled and/or smaller diameter tubes, and is often used as the final cold working step. By rolling, we are able to achieve exceptional control over dimensional tolerances and surface finish while also minimizing material loss and improving the metals microstructure.

Benefits

  • Higher Strength & Hardness Properties
  • Size Accuracy
  • Enhanced Appearance
  • Uniform Micro-structure
  • Easier To Machine
  • Superior Finish In Subsequent Manipulations

Packaging

tubes can be individually sleeved in paper or plastic and/or packaged in our unique cardboard spacers to ensure no damage occurs during transit. All tubing is packed in either wooden crates lined with wax craft paper, wooden cases, or standard cardboard boxes. Plastic end caps that prevent foreign material from getting inside the tubes are also available upon request.
