Poliertes Edelstahlblech
Polished stainless sheet metal includes multiple surface types such as 2B, BA, gebürstet (No.4/HL), and mirror (8K) endet. Darunter, 2B is the most common base surface used for further processing.
- Beschreibung
Polished stainless sheet metal refers to stainless steel sheets that have undergone surface finishing processes to achieve smooth, reflektierend, or semi-reflective appearances. These finishes are widely used in architecture, Geräte, Aufzüge, and decorative applications where surface quality and appearance are important.
Polished stainless steel is not a single surface type, but a group of different finishing levels ranging from matte industrial surfaces to high-gloss mirror finishes.
Common Surface Finishes of Stainless Steel Sheet
Stainless steel sheets can be produced or processed into several standard surface types:
1. 2B Fertig (Most Common Industrial Surface)
| Besonderheit | Beschreibung |
|---|---|
| Oberflächentyp | Kaltgewalzt, mattes Finish |
| Aussehen | Smooth but non-reflective |
| Reflexionsvermögen | Niedrig |
| Anwendung | Industrial and general fabrication |
2B is the most widely used base finish for stainless steel sheets.
2. BA-Abschluss (Blankgeglüht)
| Besonderheit | Beschreibung |
|---|---|
| Oberflächentyp | Bright heat-treated surface |
| Aussehen | Semi-gloss reflective |
| Reflexionsvermögen | Medium |
| Anwendung | Haushaltsgeräte, dekorative Paneele |
BA surface is already brighter than 2B.
3. Nr. 4 gebürstetes Finish
| Besonderheit | Beschreibung |
|---|---|
| Oberflächentyp | Linear brushed texture |
| Aussehen | Satin, directional grain |
| Reflexionsvermögen | Niedrig bis mittel |
| Anwendung | Elevators, Innenausstattung |
4. Hochglanzpoliert (8K Polished)
| Besonderheit | Beschreibung |
|---|---|
| Oberflächentyp | High mechanical polishing |
| Aussehen | Highly reflective like a mirror |
| Reflexionsvermögen | Sehr hoch |
| Anwendung | Luxuriöse Dekoration, Architektur |
5. Haaransatz-Finish (HL)
| Besonderheit | Beschreibung |
|---|---|
| Oberflächentyp | Long linear brushing |
| Aussehen | Fine directional lines |
| Reflexionsvermögen | Medium |
| Anwendung | Modern interior design |
Can 2B Stainless Steel Be Polished into Mirror Finish?
Yes — 2B stainless steel sheet can be polished into a mirror or polished surface, and this is a very common industrial process.
Why 2B Is Often Used as a Base Material
- Smooth and uniform surface from cold rolling
- Good thickness consistency
- Free from heavy texture or deep scratches
- Easy to further process (Polieren, Bürsten, Beschichtung)
Aufgrund dieser Eigenschaften, 2B is widely used as the starting surface for polished stainless steel products.
Polishing Process from 2B to Mirror Finish
Schritt 1: Oberflächenreinigung
- Remove oil, dust, and impurities
- Ensure uniform base surface
Schritt 2: Mechanical Grinding
| Stage | Funktion |
|---|---|
| Coarse grinding | Removes surface defects |
| Medium grinding | Smooths surface irregularities |
| Fine grinding | Prepares for polishing |
Schritt 3: Feines Polieren
- Uses polishing wheels and compounds
- Gradually increases surface reflectivity
- Eliminates grinding marks
Schritt 4: Spiegelveredelung (8K Level)
- Ultra-fine polishing process
- Produces high reflectivity surface
- Achieves mirror-like appearance
Important Notes About 2B Polishing
Although 2B can be polished into a mirror finish:
- Final quality depends on base steel quality
- Low-grade 2B may show defects after polishing
- Higher quality 2B (gute Ebenheit) gives better mirror results
- Not all 2B sheets are suitable for high-end mirror finishing
Comparison of Surface Finishes
| Oberfläche | Reflexionsvermögen | Processing Capability |
|---|---|---|
| 2B | Niedrig | Excellent base material |
| BA | Medium | Decorative use |
| Gebürstet | Medium | Scratch-hiding finish |
| Spiegel (8K) | Sehr hoch | High-end decorative use |
