A NATURAL BEAUTY from the very beginning. Long lasting attraction, year after year, with practically zero need for maintenance. Use SSAB COR-TEN® steel to make your mark as an architect, and let it contribute to sustainability at the same time. Genuine SSAB COR-TEN® steel is produced by SSAB under a license from US Steel Corporation.
SSAB COR-TEN® steel is a versatile material that is manufactured under total process control. The steel’s purity, optimized chemical composition, consistent mechanical properties, tight dimensional tolerances and excellent surface quality allow for predictable and problem-free performance that gives you the freedom to truly express your vision as an architect. Bend it. Perforate it. Mix it. There are endless opportunities to bring a natural beauty to the environment it is located in. Buildings that use SSAB COR-TEN® steel have been rewarded many times over for innovative and sustainable design.
PATINA FORMATION PROCESS. 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.
