Could've Should've is an interactive map showing the benefits of galvanizing. The map features a Flickr feed of images showing examples of galvanised and corroded steel which appear as markers on the map.
"Steel is all around us and plays a vital role in our everyday lives. It is used to build the places within which we live and work. We rely on it to carry our energy and communication networks, in fact without it, we would find it difficult to enjoy many activities that we take for granted."
