Mirror Finish Stainless Steel Roll Forming Material Guide: Coil Sizes, Properties & Applications
Mirror Finish Stainless Steel Roll Forming Material
1. Overview of Mirror Finish Stainless Steel in Roll Forming
Mirror finish stainless steel is a highly polished surface finish that provides a reflective, glass-like appearance. It is typically achieved through mechanical polishing of stainless steel to create a smooth, highly reflective surface.
In roll forming, mirror finish stainless steel is used in high-end architectural, decorative, and design applications where appearance is critical.
Compared to BA and brushed finishes, mirror finish offers the highest level of reflectivity but requires careful handling during processing.
2. Material Composition & Structure
Mirror finish refers to the surface finish, not the material grade.
It is commonly applied to:
- 201 stainless steel
- 304 stainless steel
- 316 stainless steel
- 430 stainless steel
Structure
- Stainless steel base material
- Mechanically polished surface
- Highly reflective finish
