What finishes are suitable for exterior use ?
    For the Feron and Foundry collections, the Black and Patine have undergone an anti corrosion process and we guarantee these finishes provided our maintenance instructions are followed.  See Terms and Conditions 
Likewise, for the Ferramenta range, Antique Black and Silver Zinc are guaranteed. The Antique Grey Iron finish is a special anti corrosion paint which has proved durable when properly maintained.

Brass will eventually tarnish and the rust finish will rust !
