COR-TEN/CORTEN STEELS
Weather resistant structural steel. The anticorrosive properties of weather resistant steel are better than those of other structural steels in many applications. The steel is self-protecting: the rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion. The steel is an economical, long-lasting and fully recyclable material.
TYPICAL APPLICATIONS: The steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, building cladding, metal sculptures (Angel of the North), agricultural vans, railway wagons, chimneys, bridges, water pipes, fans, boilers, tanks and containers, exhaust systems, vehicles and equipment constructions.
All steel is supplied with full mill test certificates to DIN EN 10204-3.1.
