Product Description
Mirror finish refers to the surface condition of stainless steel, technically classified as "8K" in the industry. The mirror effect is achieved through multiple polishing stages, creating a highly reflective, smooth surface.

Application Areas
- Architectural Decoration: Wall cladding, columns, ceilings, elevator interiors. High reflectivity enhances spatial aesthetics and creates a modern, luxurious feel.
- Industrial Manufacturing: Automotive parts, chemical machinery, and food processing equipment. Mirror finish reduces friction and improves cleanability.
- Food-Grade Applications: Commercial kitchen equipment, food processing machinery, restaurant countertops and backsplashes.
Important Considerations
| Factor |
Recommendation |
| Thickness vs. Mirror Effect |
When the thickness exceeds 6mm, the mirror effect decreases noticeably, and the processing cost increases significantly. |
| Grade Selection |
8K is sufficient for most architectural decoration. 10K is recommended only for precision industrial or high-end medical applications. |
| Surface Protection |
Mirror surfaces are prone to fingerprints and scratches. Apply PVC protective film immediately after polishing and remove only before installation. |
