When rust goes right
If you were visiting any big city in the last ten or so years, you were probably noticed some buildings or modern art sculptures that look like they were terribly rusted. Those pieces of the urban landscape should stand out of their surroundings, because everything around them seem to be maintained pretty well. And the rusty building or sculptures don’t look neglected as well, but rather warm in their rustic antique appearance.
That’s because the rust on such objects, whether it’s a building facade, sculpture or a modern art installation, is, in fact, controlled. This is so called COR-TEN steel of which such objects are made. Being exposed to the weather the sheets of Corten steel are quickly covering in a thin layer of rust. However, this rust doesn’t go deeper into the steel. It’s forming a stable protective layer instead.
