It is a process of spraying a minute glass beads on the metal surface with a certain level of pressure. It is used widely for exterior and roof materials of buildings and press plate since it could create evenly dull surface. It also goes well in combination with mirror finish.

1) Limitation of Masking
High-pressure spraying is impossible, if a certain part of the surface is masked through silk screen printing. 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.
