광택 스테인레스 판금
Polished stainless sheet metal includes multiple surface types such as 2B, 학사, 브러시 (No.4/HL), 그리고 거울 (8케이) 마무리. 그 중, 2B is the most common base surface used for further processing.
- 설명
Polished stainless sheet metal refers to stainless steel sheets that have undergone surface finishing processes to achieve smooth, 반사적, or semi-reflective appearances. These finishes are widely used in architecture, 가전제품, 엘리베이터, 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 마무리 (Most Common Industrial Surface)
| 특징 | 설명 |
|---|---|
| 표면 유형 | 콜드 롤, 무광택 마감 |
| 모습 | Smooth but non-reflective |
| 반사율 | 낮은 |
| 애플리케이션 | Industrial and general fabrication |
2B is the most widely used base finish for stainless steel sheets.
2. 학사 마무리 (밝은 소둔)
| 특징 | 설명 |
|---|---|
| 표면 유형 | Bright heat-treated surface |
| 모습 | Semi-gloss reflective |
| 반사율 | 중간 |
| 애플리케이션 | 가전제품, 장식 패널 |
BA surface is already brighter than 2B.
3. No.4 브러시 마감
| 특징 | 설명 |
|---|---|
| 표면 유형 | Linear brushed texture |
| 모습 | 공단, directional grain |
| 반사율 | 낮음 ~ 중간 |
| 애플리케이션 | 엘리베이터, 실내 장식 |
4. 거울 마감 (8K Polished)
| 특징 | 설명 |
|---|---|
| 표면 유형 | High mechanical polishing |
| 모습 | Highly reflective like a mirror |
| 반사율 | 매우 높음 |
| 애플리케이션 | 럭셔리 장식, 건축학 |
5. 헤어 라인 마감 (HL)
| 특징 | 설명 |
|---|---|
| 표면 유형 | Long linear brushing |
| 모습 | Fine directional lines |
| 반사율 | 중간 |
| 애플리케이션 | 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 (세련, 브러싱, 코팅)
이러한 속성으로 인해, 2B is widely used as the starting surface for polished stainless steel products.
Polishing Process from 2B to Mirror Finish
단계 1: 표면 청소
- Remove oil, 먼지, and impurities
- Ensure uniform base surface
단계 2: Mechanical Grinding
| Stage | 기능 |
|---|---|
| Coarse grinding | Removes surface defects |
| Medium grinding | Smooths surface irregularities |
| Fine grinding | Prepares for polishing |
단계 3: 미세연마
- Uses polishing wheels and compounds
- Gradually increases surface reflectivity
- Eliminates grinding marks
단계 4: 거울 마무리 (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 (좋은 평탄도) gives better mirror results
- Not all 2B sheets are suitable for high-end mirror finishing
Comparison of Surface Finishes
| 표면 | 반사율 | 처리 능력 |
|---|---|---|
| 2비 | 낮은 | Excellent base material |
| 학사 | 중간 | 장식용 |
| 솔질된 | 중간 | Scratch-hiding finish |
| 거울 (8케이) | 매우 높음 | High-end decorative use |
Applications of Polished Stainless Sheet Metal
Polished stainless steel sheets are widely used in:
- 엘리베이터 내부 및 문
- 호텔 로비 장식
- Architectural wall panels
- 주방 장비 표면
- Luxury retail displays
- Furniture decorative panels
- Signage and branding systems
