The mirror finish of stainless steel, in simple terms, refers to the polishing of the stainless steel surface. The polishing methods are divided into physical polishing and chemical polishing. Local polishing can also be carried out on the surface of stainless steel, with polishing grades divided into ordinary polishing, ordinary 6K, fine grinding 8K, and ultra strong fine grinding 10K. The mirror gives people a feeling of simplicity and fashion in the future.
Stainless steel mirror panels are widely used, architectural decoration, interior decoration, office decoration, elevator decoration, industrial decoration, equipment decoration and other decoration, decoration and decoration fields have been widely applied.
The main stainless steel mirror panel products are: 201 stainless steel mirror panel, 304 stainless steel mirror panel, 316 stainless steel mirror panel and a series of color stainless steel mirror panels.

Mirror / 6K
|
6K is equivalent to BA finish
6K with rough grinding and polishing is slightly less effective than a mirror

Mirror 8K
|
8K is after polishing and grinding, the surface of the stainless steel plate is as bright as a mirror and can reflect objects and people
