It is a process to leave the non-directional mark of polishing on the surface of steel. Various products such as 3S Vibration, B-Vibration and A-Vibration are possible through manipulation of various automatic devices. It can feature various patterns through the combination with mirror or line etching since it can produce even semi-gloss surface.

1) Limitations of Masking
In case certain parts of the surface are masked through silk screen printing like Bead Blasting, it is difficult to polish the product into a very strong media. So it is more desirable that the product is masked through protective tape rather than printing. If it should inevitably be masked through printing, a higher level of brilliance cannot be avoided.

2) Harmony With Line Etching
Effects of various patterns could be created in two tones. Various patterns are available through silk screen printing without etching.
