My TRIPLE is rusting – is that normal?

Absolutely—this look is designed by nature. TRIPLE’s Corten steel develops its characteristic patina over time, making it not only more resilient, but also uniquely striking. When you first receive TRIPLE, you'll notice a matte black “mill scale” finish. This gradually transforms into a warm rust tone over about 1.5 to 2 years. Eager to accelerate the effect? A rust accelerator like CortenPlus can help speed up the process—simply order CortenPlus to get started.

Please note: During the early weathering stages, Corten steel may show uneven coloration or allow some rust particles to wash out. This is all part of the natural oxidation and will settle over time. Because of this, we recommend placing Corten products away from delicate or premium surfaces like natural stone or high-end tiles.
