No. 8 Mirror Finish

Fine abrasive polish and buff are used on cold-rolled and bright-annealed sheets to create a mirror-like surface.

HL Finish

Cold-rolled and bright-annealed stainless steel. By applying abrasive and oil on the No.4 Finish, grain lines (soft stain hair-line) are then able to be brushed on the surface.

2B Finish

Undergoes the process of cold rolling, heat treatment, and pickling. A luster surface is achieved by skin pass. With a bright and smooth surface, it is easier for further grinding to obtain a brighter surface. 2B is the basis for most polished finishes.

Star Light

Special electrical coating techniques along with multiple layers of etching allow sheets to resemble star sight. It is characterized by being fingerprint-free and anti-scratch.

Etching

Patterns are pre-designed by designers or requested by end applications. Chemical etchings present these patterns on the surface.

BA Finish

Bright heat treatment after cold rolling with further skin pass to produce luster surface. 

* Other finishes are also available up to request.

* The scratches and dust on the surfaces are produced by the sampling process. It does not stand for the quality of Grace Alloy Corp.

   Please refer to the part without scratches and dust.
