Drawn over Mandrel (DOM) tubing is defined by 3 different dimensions:
• Inside Diameter (ID) • Outside Diameter (OD) • Wall Thickness
When ordering, only 2 of the 3 tolerances must be defined. Alro Steel purchases
DOM tubing, for general inventory, to the outside diameter and inside diameter.
If you do not see a size listed, please contact your Alro representative.
