- Описание
Corten steel sheets are weather-resistant steel plates designed to form a stable protective rust layer after exposure to the atmosphere. This oxidation layer helps reduce further corrosion and gives the steel its characteristic rusted appearance.
Corten steel is widely used in:
- Архитектурные фасады
- Landscape design
- Bridges and structural engineering
- Уличные скульптуры
- Garden screens and wall panels
- Промышленные структуры
The name “Corten” comes from:
- COR = corrosion resistance
- TEN = tensile strength
Why Different Corten Steel Grades Exist
Different weathering steel grades are developed for:
- Different strength requirements
- Structural engineering standards
- Atmospheric corrosion resistance levels
- Welding and fabrication performance
- Regional industry standards
Some grades focus more on decoration, while others are designed for heavy structural applications.
Common Grades of Corten Steel Sheets
1. Кортен А
Характеристики
- One of the most common weathering steel grades
- Отличная устойчивость к атмосферной коррозии
- Good decorative rust appearance
- Lower phosphorus structural limitation than structural grades
Приложения
- Architectural wall panels
- Decorative screens
- Ландшафтные сооружения
- Садовый бордюр
- Exterior cladding systems
Corten A is mainly used for architectural and decorative applications.
2. Кортен Б
Характеристики
- Higher structural strength than Corten A
- Better heavy-load performance
- Хорошая свариваемость
- Strong outdoor durability
Приложения
- Мосты
- Structural steel frameworks
- Железнодорожные вагоны
- Промышленные здания
- Heavy outdoor structures
Corten B is more suitable for structural engineering projects.
