The Weathering Steel Finish<\/strong><\/span><\/h2>\n<\/div><\/div><\/div><\/div><\/div>

<\/u>Weathering steel, often known by the brand name ‘Corten’, works by deliberately rusting on the outside to protect itself on the inside. Regular steel rusts continuously because its outer layer of rust is porous, flaky, and allows air and moisture to keep soaking deeper until the metal degrades completely. Corten, however, is mixed with small amounts of specific alloys like copper, chromium, and nickel. When exposed to the elements – repeatedly wetting and drying, these extra elements react to form a dense, tightly bound surface oxide layer known as a patina. Instead of flaking away, this warm, orange-brown rust barrier seals the surface, blocking water and oxygen from penetrating any further and effectively stopping the corrosion process in its tracks without needing paint or protective coatings.<\/em><\/p>\n<\/div><\/div><\/div>
