Naturally, you want to make a COR-TEN® façade look as good as possible during the years. Since COR-TEN® is self-protecting it needs no regular attention or maintenance, as is the case for almost all other façade materials. When installing COR-TEN® there are some things to consider:
The perfect patina
1.
The patina that protects the steel and gives it its distinctive color is formed when COR-TEN® is subjected to alternating wet and dry conditions.
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.
Best practice in the case of lap joints is to avoid direct contact between steel surfaces and leave a ventilation gap between steel sheets. Use screws of acid proof stainless steel in screw connections and EPDM or neoprene gasket to avoid galvanic corrosion.
COR-TEN® weathering steel sheets can be perforated in any way you like. Create your design using round, square, rectangular holes, customized texts, logos and images. Anything is possible. In these cases, it’s possible that run-off from these holes can affect the color of the patina.
Installing a beauty
2.
To maintain an even color, it’s recommended that water can run off freely and not stay on the surface.
