Mechanical polishing is used to provide a homogenous and bright appearance. It is accomplished by grinding the tubing with finer and finer abrasive grits to achieve the desired finish or surface roughness. Tubing can be provided in a variety of surface finishes on the Outside and Inside Diameter based on customer requirements.

For ornamental purposes, the outside can be provided in mill finish, bright finish, 180 grit polish, 240 grit polish, 400 grit polish, and even finer depending on customer requirements. For sanitary tubing, the outside and inside are polished to provide a smooth finish to avoid biological buildup on the tubing service. Mechanical polishing can also be used to prepare tubing for electropolishing so that the final desired surface finish is successfully achieved.
