Corten Steel

Origin

Australian-fabricated, weathering steel grade

Why we use it

Used for retaining edges, water containment, and precise garden geometries. Its oxidation forms a protective skin and a chromatic anchor in the planting.

Weathering

Reaches its terminal patina in roughly eighteen months. After that, it changes only with weather.

Maintenance

None. Allow weeping in the first year; protect adjacent paving where staining is unwanted.
