Corten Rainscreen Cladding

A group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance. The corrosion process usually takes about 18-36 months.

Featured Project

Specified by Bond Bryan Architects the development sought to respond to the historical significance of the site whilst creating a modern and contemporary facility for the University. Sotech worked very closely with Horbury Building Systems Ltd to accommodate the client brief particularly around the perforated corten screens.  Over 1100m2 of 2mm corten steel rainscreen cladding cassettes and bespoke perforation screens were supplied to the project, along with 200m2 of Alucobond Soffits to the main entrance area. The ppc colours of the unique aluminium feature pods were selected to create the dramatic contrast between the pantone colour and the corten.

The building also features reveals and soffits, a solar voltaic support frame visible through the rainscreen and the copings to the glass and brick façades. The saw toothed soffits and fascia’s were provided in the university corporate colours to enhance the identity of the project. Corten is a self-protecting material, the rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion.  The material weathers to a natural brown colour which darkens gradually, the corrosion process usually takes 18-36 months.

Benefits

The anticorrosive properties of weather resistant steel are better than those of other structural steels.

The material is self-protecting, the rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion.

Corten Steel reaches a stable oxidation point where further oxidation may occur but does not effect the quality of the steel.

The material is economical, long-lasting and fully recyclable.

The use of un-coated weather resistant steel in steel structures saves surface treatment costs.

Weathers to a natural brown colour which darkens gradually.
