COR-TEN® is very resilient when coming in contact with most other materials. A word of caution is to avoid prolonged contact with wood, copper or other noble metals, chemicals or de-icing salts.
When installing COR-TEN® on a building, ensure a free airflow together with water running off freely and moisture escaping from the metal’s surfaces and back side. Ventilation space should be full-length and at least 30 mm in width.
Before installation, COR-TEN® should be stored in dry conditions to ensure a similar patina formation on all steel plates.
Use screws of acid proof stainless steel in screw connections and EPDM or neoprene gasket to avoid galvanic corrosion.
For best result, remove welding splashes or any other impurities from the surface.
Best practice in the case of lap joints is to avoid direct contact between steel surfaces and leave a ventilation gap between steel sheets.
