They are produced by roll-forming ROUND tubes through a
series of rollers and dies. This process is cold-rolled, and no
further processes (such as stress-relieving) are performed afterwards.
The round tubes can be 4130, Mild Steel, Aluminum, Titanium ("CP" Grade is preferred), or Stainless Steel.
 Wall thicknesses can range from .032 - .065, based on availability of round material.
There are no tolerances on the finished dimensions. The major and
minor are going to be close to the listings, but the type and grade of
material are going to affect the finished results, as well as the wall
thickness.
There are no material test reports (sometimes referred as "material
certifications") available for the finished roll-formed material. Test
reports are available for most of the original round tubes at an
additional no additional cost. Be sure to discuss with your sales representative.
