G - Rough
The tube does not receive any particular treatment after polymerisation and has a reflective surface with a thin, 2mm-pitch, spiral pattern produced by the heat-shrink film ...
All the tubes, once printed, show a thin spiral engraved on the outside, a finishing we call "Rough", while the inside of the tube is always smooth. With subsequent treatments we can also grind or paint the outer surface.
More details:
The tube has a mat finish with a thin spiral pattern, which gives the product an attractive, non-slippery surface that feels nice to the touch. This finish is ideal for ...
After polymerisation, the tube undergoes a surface polishing process which reduces roughness making the tube’s surface smooth and flowing to the touch. This process also reduces ...
After the polishing, a paint may be applied on the tube. This will make the surface smooth and shiny giving the tube a beautiful aesthetic appearance while protecting the tube ...
With this type of finish we can control the outer diameter of the tube allowing for very tight tolerance values to be achieved. This process, however, is relatively expensive and ...
