Graepels have over 57 years experience in dealing with a wide range of metals. We manufacture a large selection of products in Corten.
In 2014 Graepels designed and manufactured a Perforated Walkway for Hugo Buggs’ Chelsea flower show garden which won gold. We understand the capabilities and considerations when choosing materials for their application and perforation.
SECULAR CHANGES IN RUST APPEARANCE
In the inital stage of application, COR-TEN shows a yellowish appearance. This is followed by a gradual change in the colour of the protective rust from brown to a ‘stablised’ dark brown after one to two years in ‘general’ application environments. Afterwards, the colouration shows no clear change, except perhaps to a deeper dark brown.
