Base finishes are the first processed finishes on the industrial 2B or BA sheets raw material. They can be produced on one side or, on both sides of the sheet. Finishes like VIB, BB and Satin can be produced with various density, roughness and reflectivity, to match specified appearance.
Only at our factory, after the usual N8 Mirror polishing on the Automatic polishing lines, we do manual buffing with a special liquid of our own 30 years old recipe and custom made pads of the finest grit.

Surface Scan Test shows Ra=0.667uin (0.01 micron) This is the highest quality Mirror finish on stainless steel sheets in the world.
