How long does Corten garden edging last?

Corten steel garden edging is highly durable and long-lasting. On average, it can last 50+ years depending on the environment and thickness of the steel.

Factors Affecting Lifespan:

Climate Conditions – In dry climates, Corten steel forms a protective rust layer and lasts longer. In humid or coastal areas, the lifespan may be reduced due to increased corrosion.

Steel Thickness – Thicker Corten steel (e.g., 3mm or more) lasts longer than thinner sheets.

Soil & Water Exposure – If constantly exposed to moisture and acidic soils, it may degrade faster.

Corten steel garden edging is highly durable and aesthetically appealing due to its unique rusted appearance. This weathering steel forms a protective oxide layer on its surface, preventing further corrosion and allowing it to last over 50 years in outdoor environments. Unlike traditional metals, Corten steel does not require additional coatings or frequent maintenance, making it ideal for long-term landscape use.

In dry climates, the oxidation layer stabilizes quickly, whereas in humid or coastal areas, higher moisture and salt levels may accelerate corrosion. To extend its lifespan, it is recommended to avoid prolonged water exposure and ensure proper drainage. Additionally, opting for thicker steel (such as 3mm or more) can enhance durability.

Overall, Corten steel garden edging is a low-maintenance and cost-effective choice, offering both structural strength and an attractive weathered look that enhances any outdoor space.
