We open our COR-TEN® steel line of products.

A natural beauty from the very beginning. Long lasting attraction, year after year, with practically zero need for maintenance. Use COR-TEN® steel to make your mark as an architect, and let it contribute to sustainability at the same time. Genuine COR-TEN® steel is produced under a license from US Steel Corporation.


While many admire the beauty of COR-TEN® steel very few understand its unique qualities and the extent of its full potential as interior furniture & design aesthetic. We seek to change that.

At first, the steel begins to rust in the same fashion as any other carbon steel, when exposed to wet and dry weather conditions. However, as time passes, the rust layer transforms into a dense patina layer, sealing-off the steel surface, resisting further corrosion. The color changes from fresh, newly developed orange-brown, to light and eventually dark brown.

The speed of change and the final color of the steel depend on the atmospheric conditions of a site and the surrounding air quality. Sulfur dense atmospheres will speed up the oxidation process and result in a darker patina. Frequent cycles of wet and dry weather conditions will also speed up oxidation.
