엣지 스틸 코르텐
Kantstål Corten can be manufactured from multiple weathering steel grades, each with different strength levels, 화학 성분, and application focuses. ASTM A588 provides high-strength structural performance, S355J2W offers balanced European standard properties, while SPA-H and Q355NH are widely used in industrial and landscaping applications. Selecting the correct grade ensures optimal performance, 내구성, and aesthetic stability in outdoor environments.
- 설명
Kantstål Corten refers to Corten steel edge strips or weathering steel flat bars used in landscaping, edging systems, and structural outdoor applications. These products are manufactured from different international weathering steel grades, each with slightly different chemical composition, 기계적 강도, and corrosion performance.
Understanding the differences between common Corten steel grades is important for selecting the right material for landscape edging, garden borders, and outdoor structural projects.
Overview of Common Corten Steel Grades
Corten steel is not a single grade but a group of weathering steels defined by different international standards.
Major Grades Used in Kantstål Corten Products
- ASTM A242
- ASTM A588
- ASTM A606 유형 4
- S355J2W (표준)
- S355J0W
- SPA-H (JIS standard)
- Q355NH (Chinese standard)
Each grade is designed for atmospheric corrosion resistance but differs in strength level and application focus.

내식성 성능
All Corten grades share the same weathering principle, but performance varies slightly:
- ASTM A588: Excellent long-term outdoor durability
- S355J2W: Strong performance in European climate conditions
- SPA-H: Stable performance in container environments
- Q355NH: Good performance in industrial and urban environments
- ASTM A606 유형 4: Suitable for thinner decorative applications
응용 프로그램의 차이점
| 등급 | 일반적인 응용 |
| ASTM A242 | 교량, structural steelwork |
| ASTM A588 | Heavy infrastructure, 교량, towers |
| ASTM A606 유형 4 | 장식 패널, architectural sheets |
| S355J2W | 건물 정면, construction projects |
| SPA-H | 선적 컨테이너, transport equipment |
| Q355NH | 산업구조, outdoor equipment |
Suitability for Kantstål Corten (Edge Steel)
For garden edging and landscape Kantstål applications, 가장 일반적으로 사용되는 등급은:
- S355J2W (most common in Europe)
- Q355NH (widely used in Asia)
- ASTM A606 유형 4 (for thinner decorative edging)
These grades offer a good balance of:
- Formability for bending and shaping
- Sufficient strength for soil pressure
- Stable weathering performance
- 장기간의 옥외 내구성
