Stainless steel polished surface
No. 3: Represented by 3A and 3B. 3A: The surface is evenly ground with an abrasive particle size of 80-100. 3B: matte finish, the surface has a uniform straight, usually with a particle size of 180 to 200 in the 2A or 2B plate on the disposable polishing.
No.4: Unidirectional surface finish, poor reflectivity, this surface finish may be the most versatile in architectural applications. The process step is to use coarse abrasive polishing, and finally with a particle size of 180 abrasive grinding.
No.6: A further improvement on No. 4, polishing No.4 surface with Tampico polishing brush in abrasive and oil media. This surface finish is not available in British Standard 1449 but can be found in U.S. standards.
No.7: Known as Bright Polishing, it polishes a surface that has been finely ground but still scratches. 2A or 2B plates are usually used, using a fiber or cloth polishing wheel and the corresponding polishing paste.
No.8: Mirror polished surface, high reflectivity, usually referred to as mirror surface processing, because it reflects the image is very clear. Polishing the stainless steel with a fine abrasive and then grinding with a very fine polishing paste. It should be noted in architectural applications that such surfaces leave fingerprints for use in areas where there is a large flow of people or where people often touch. Fingerprints can certainly be erased, but sometimes affect the appearance.
