Laser cut for better accuracy, surface finish and squarer edges compared to plasma cut alternatives.
Most discs have a dull polished (satin / brushed / grained) finish to one face which is protected by a peel off protective film, but the rear face is not polished and may be scratched and marked.
Some discs may be scratched and marked on both faces.
If the finish is important please let us know and we will select discs accordingly.
