Like a fine wine, weathering steel is enriched by air and enhanced with age. When exposed to the natural environment, this magical steel develops a beautiful patina which serves as protective armour and is the basis for the steel’s trademark purplish brown colouring.
The marvellous paradox of
weathering steels
is that rust protects the steel from rust ! Weathering steel is also known as
corten steel
. This comes from the original brand name COR-TEN which was registered in 1933 by US Steel Corporation.
