Cold Rolled Steel C1026 (DOM Tube)

Grade Summary: DOM Steel Tube is typically produced using uniformly high quality C1026 steel strip which is formed and electric resistance welded into its basic shape. What makes DOM different to ERW Tube is that after annealing to produce a uniform grain structure throughout, the tube is then cold drawn over a mandrel to give it uniform  shape, close wall tolerances and high physical properties. The cold working process also works the weld area to produce a weld line that virtually disappears, causing DOM tube to appear seamless.

Typical Applications:  Mechanical, hydraulic cylinders, shaft, tight tolerance requirements

Available products: Round Tube

Product Notes:

  • All Round Tube is measured in the following way: The outside diameter (Inches), the wall thickness (Inches) and the inside diameter (Inches). Tube products are used in structural applications – This product is not used for the movement of any volume, such as Air, Water or Oil (Pipe should be used)
  • Best Product to telescope tubes with is DOM Steel Tubing (found under a Cold Finished or Cold Rolled category – The Grade on DOM is C1026), as it does not have a weld on the inside of the tube because the weld flash was removed; almost every other tube or pipe has a weld on the inside of the tubing. The weld will stop you from telescoping one tube into another. With DOM Steel Tubing plan to allow at least 0.010 (Inches) between the OD (outer diameter) and ID (inner diameter) that you intend to telescope. However, this still will not guarantee that your tubes will telescope. Tubing has OD (outside diameter) and ID (inside diameter) tolerances; these tolerances tend to run larger on OD’s (outer diameters) and smaller on ID’s (inside diameters). So, even if you allow 0.010 (Inches), your tube still may not telescope.
