Standard Tube Finishes
Mill Finish - Standard smooth, semi reflective finish, as produced at the mill with no further treatments applied.
May contain scuffs and scratches from transportation, handling and shearing operations, further surface preperation may be needed for cosmetic applications.

General Tube Information
Tube sizes refer to the size of the OUTSIDE diameter of the tube. The listed size is subject to manufacturers tolerances for outside diameter and wall thickness. Tubes are produced in extruded or drawn tube. Small diameter and thin wall tubes are generally "drawn" and maintain their mechanical properties and tight tolerances.
Larger diameter and thicker wall tubes are generally extruded.
