What is Good Quality NO.8 / 8K Mirror Stainless Steel?

 

8K stainless steel, also called mirror stainless steel, has a smooth, mirror-like surface. To assess its quality, consider these points:

1. Surface Quality

A good 8K sheet should be free of scratches, dents, or defects, with a clear reflection instead of a blurry one.

2. Clear Reflection

Place a paper with text in front of the sheet — the clearer the reflection, the better the quality.

3. Uniform Color

A quality sheet has a consistent metallic shine without dark spots or uneven shades.

4. Smooth Surface

Good 8K sheets should be flat and free of ripples, color bands, or streaks.

5. Corrosion Resistance

High-quality 8K stainless steel offers strong protection against rust and corrosion.

6. Precision Production

Top-quality 8K sheets are polished with advanced machines for a flawless finish with no streaks.

7. Protective Film

A good 8K sheet has a secure protective film that prevents scratches and is easy to remove.
