Stainless steel has been used in the last twenty years not only for new building projects, but also for renovations of buildings that feature glass, wood, or cement. The reason for this is not just an aesthetic choice, but also because stainless steel has many qualities that make it an ideal exterior material choice as it is strong, resistant to corrosion, easy to clean, and above all, does not require long term financial maintenance costs. Presently there are numerous examples of esteemed public and private buildings that feature stainless steel exteriors, most of which are to be found in northern Europe.
