What is Weathered Steel Edging?
Weathered steel edging, also known as Corten steel border edging or classic corten steel edging, is a versatile landscaping solution that enhances both the aesthetics and functionality of outdoor spaces.

Made from a specialized steel alloy, it develops a distinctive rusted patina over time. This natural rusting process not only creates visual appeal but also forms a protective layer that increases durability and longevity.
Applications:
Separates flower beds from lawns
Defines garden pathways
Creates clean, structured borders for landscaping
Weathered steel is known for its resistance to corrosion, requiring minimal maintenance. It performs well in climates with annual rainfall from 250 mm to 2000 mm and temperatures ranging from -20°C to 50°C. Gnee core edge flexible steel lawn edging corten allows curved or straight designs, making it adaptable to any landscape layout.
