Round Tube

Southside Steel stocks round tube at a variety of sizes and lengths.  All our steel round tube is available in stock lengths or cut to length. Email us about our fabrication processes available for round tube such as coping, miter cutting, welding, etc.

Steel Round Tube Specs: ASTM A513, type 5.

Available Finishes: Stainless, Aluminum and Hot Rolled Steel

  • Uses: Mechanical uses such as shafts, axles, bushings, steering columns, vehicle framing, pipe sleeves etc.
  • Know the numbers: Round Tube, electric weld and DOM is measured by the outside diameter, not the inside diameter (like our steel pipe-link to pipe page).  Example:3” OD x 0.250” wall has an outside diameter of 3”, a wall thickness of 0.250” and an inside diameter of 2.5”.
  • NOTE: All of the DOM material that we stock is seamless, meaning that, unlike our structural pipe and electric weld, there is not weld seem inside the material.

Available Stock Sizes: 20ft lengths or custom cut to any size.
