ポリッシュステンレス板金
Polished stainless sheet metal includes multiple surface types such as 2B, BA, 起毛した (No.4/HL), and mirror (8K) 仕上げ. Among them, 2B is the most common base surface used for further processing.
- 説明
Polished stainless sheet metal refers to stainless steel sheets that have undergone surface finishing processes to achieve smooth, 反射性の, or semi-reflective appearances. These finishes are widely used in architecture, 家電製品, エレベーター, 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仕上げ (Most Common Industrial Surface)
| 特徴 | 説明 |
|---|---|
| 表面の種類 | コールドロール, マット仕上げ |
| 外観 | Smooth but non-reflective |
| 反射率 | 低い |
| 応用 | Industrial and general fabrication |
2B is the most widely used base finish for stainless steel sheets.
2. BA仕上げ (光輝焼鈍)
| 特徴 | 説明 |
|---|---|
| 表面の種類 | Bright heat-treated surface |
| 外観 | Semi-gloss reflective |
| 反射率 | 中くらい |
| 応用 | 家電製品, 装飾パネル |
BA surface is already brighter than 2B.
3. No.4 ブラッシュ仕上げ
| 特徴 | 説明 |
|---|---|
| 表面の種類 | Linear brushed texture |
| 外観 | サテン, directional grain |
| 反射率 | 低から中程度 |
| 応用 | エレベーター, interior decoration |
4. 鏡面仕上げ (8K Polished)
| 特徴 | 説明 |
|---|---|
| 表面の種類 | High mechanical polishing |
| 外観 | Highly reflective like a mirror |
| 反射率 | 非常に高い |
| 応用 | 豪華な装飾, 建築 |
5. ヘアライン仕上げ (HL)
| 特徴 | 説明 |
|---|---|
| 表面の種類 | Long linear brushing |
| 外観 | Fine directional lines |
| 反射率 | 中くらい |
| 応用 | 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 (研磨, ブラッシング, コーティング)
こういった性質があるため、, 2B is widely used as the starting surface for polished stainless steel products.
Polishing Process from 2B to Mirror Finish
ステップ 1: Surface Cleaning
- Remove oil, dust, and impurities
- Ensure uniform base surface
ステップ 2: Mechanical Grinding
| Stage | 関数 |
|---|---|
| Coarse grinding | Removes surface defects |
| Medium grinding | Smooths surface irregularities |
| Fine grinding | Prepares for polishing |
ステップ 3: 精密研磨
- Uses polishing wheels and compounds
- Gradually increases surface reflectivity
- Eliminates grinding marks
ステップ 4: 鏡面仕上げ (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 (良好な平坦度) gives better mirror results
- Not all 2B sheets are suitable for high-end mirror finishing
Comparison of Surface Finishes
| 表面 | 反射率 | Processing Capability |
|---|---|---|
| 2B | 低い | Excellent base material |
| BA | 中くらい | Decorative use |
| つや消し | 中くらい | Scratch-hiding finish |
| 鏡 (8K) | 非常に高い | High-end decorative use |
Applications of Polished Stainless Sheet Metal
Polished stainless steel sheets are widely used in:
- エレベーターの内装とドア
- ホテルのロビー装飾
- Architectural wall panels
- 厨房機器の表面
- Luxury retail displays
- Furniture decorative panels
- Signage and branding systems
