DOM Tubing Applications:

  • Automotive applications
  • Industrial and construction equipment

Advantages of Dom Tubing:

DOM A513 Type 5 is a preferred choice for a wide range of mechanical tubing applications because it combines the advantages of closely controlled dimensions (OD/ID/Wall), superior concentricity, and a uniform wall thickness. In addition, DOM tubing offers smooth OD and ID surfaces, high mechanical properties, and excellent machinability.
