Product Description
Our SS 304 Mirror Finish Sheets (also known as No. 8 Finish or 8K Finish) are produced by polishing standard 2B or BA stainless steel sheets to achieve a highly reflective, mirror-like surface. The clarity and reflectivity are comparable to a glass mirror.
The base material is ASTM A240 Grade 304 stainless steel, which provides excellent corrosion resistance and formability. The ultra-smooth, glossy surface not only delivers aesthetic brilliance but also offers low dirt adhesion and easy cleaning – making it the preferred choice for both decorative and functional applications.
Product Aliases: No. 8 finish sheet, 8K mirror sheet, reflective stainless steel sheet, decorative stainless steel sheet.

Packing Method
To protect the mirror finish during transit and storage, we follow export-grade packing:
| Step | Description |
|---|---|
| 1. Interleaving | Kraft paper and foam paper between each sheet |
| 2. PVC Protection | White/blue PVC film on mirror side (low-tack, residue-free) |
| 3. Waterproofing | VCI paper + PE waterproof wrap |
| 4. Edge Protection | Cardboard or plastic edge protectors |
| 5. Bundling | Steel strapping on heavy-duty wooden pallets (heat-treated, ISPM-15 certified) |
| 6. Labeling | Mill test certificate number, grade, dimensions, and quantity |
✅ Shipping marks and handling instructions are clearly printed on each package.
