No.1 is hot rolled, annealed, pickled and passivated finishing. This results in a dull, slightly rough surface; quite suitable for industrial applications which generally involve a larger range of thicknesses.
2B finish is given a subsequent light skin pass and cold rolling operation between polishing. This is the most common finishing applied for general use.
BA finish is processed with bright annealing process after cold rolling. BA finish is carried out in a controlled atmosphere furnace or vacuum in order that oxidation is reduced to a minimum and the surface remains relatively bright. BA is commonly used in decorative purpose.
No.4 is a unidirectional short linear finishing obtained by 150 to 240 grits abrasive polishing. It is a fine décor finish applied in many field such as kitchenware or buildings.
This is also a unidirectional finish but differs from No.4 finish. They are straight long lines, and share same usage as many decorative finishings.
No. 8
(Super Mirror)
No.8 is polished by sophisticated and automatic mirror machine. The finishing looks exactly like a mirror with high reflection. It can be applied as decorative material to increase dimensional appearance.
No. 8
Thicker Plate
(Thicker Gauge)
No. 8 Thick Gauge polishing system. It is for special customer’s requirement such as chemical containers, semiconductor equipments etc.
