It's reasonable for people to avoid rust in their home, but here's one instance that rust can be not only functional, but pretty cool looking, too — weathered steel siding.
A 242, A 588, and A 606, are all types of steel, more commonly known as weathering steel, or its trademarked name, COR-TEN. It was developed to eliminate the need for painting steel, and instead develops a layer of rust after a time of being exposed to the elements. This layer of continues to develop a rusty patina, which can vary depending on time and location. COR-TEN can come smooth or corrugated, as sheets or panels, and can be installed as a rain screen. Steel is made with recycled content, is recyclable, and used in this application, it can be a very durable, modern siding option.
