- Penerangan
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.
Keluli Corten digunakan secara meluas dalam:
- Fasad seni bina
- Landscape design
- Jambatan dan kejuruteraan struktur
- Arca luar
- Garden screens and wall panels
- Struktur perindustrian
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.
