High-strength low-alloy steel, commonly known by the Corten trade name, left bare so it develops its own protective oxide surface.

About the material

Weathering steel is a low-alloy steel whose additions of copper, chromium, nickel and phosphorus change how it corrodes. Instead of the loose, flaking rust of plain carbon steel, it forms a dense, tightly adhering oxide layer that slows further corrosion.

That layer is the finish. The material is specified bare, for the deep russet surface it develops over the first years of exposure, and it is used architecturally for exactly that reason.

It needs the right conditions to work: cycles of wetting and drying. Sheltered, permanently damp or salt-laden locations prevent the oxide stabilising, and the runoff in the early years will stain adjacent concrete, masonry and paving.

Detailing — drainage, standoff, fastener compatibility and what sits below the panel — matters more with this material than with any coated product.
