![]() ![]() This process, known as bluing, will create a more corrosion-resistant surface, at least for interior exposures. Heating the steel surface in the presence of steam creates a blue tone. This black patina is created by chemically patinating the zinc surface to a blackened state. There are a number of patina solutions which can darken the steel for artistic effect. A blackened surface can be also created on galvanized steel sheet, which is essentially a steel with a zinc surface. These can be applied in a controlled environment to bring the steel to an artistic and blackened state. One such method uses blackening or bluing chemical agents. This is possible, but will require maintenance in exterior environments.īlackened steel is an artistic surface with a historic appearance. Many people want to reproduce the look of mill-finish steel. In addition to these natural appearance patina surfaces, there are a number of induced finishes which can be created on steels. Weathering Steel can be pre-weathered to reach deep and blues and maintain a more stable appearance and reduced staining. If your desire is a deep rusted aesthetic, this material provides a solution to the age-old issue of the deterioration of steels and bleeding of weathering steels. ![]() Weathering steel is also known as the product name “CORTEN” as well as copper-bearing steel for its copper alloying constituent. There are a number of steel alloys, some of which offer greater permanence, such as weathering steel. Steel’s natural oxide is soluble and thus it continues to seek oxygen and water until only dust remains. The problem to overcome with steel is its ever-changing, ever-deteriorating nature. While stunning in its possibilities of finish, steel brings difficulty in protecting these tones as weather and atmosphere pose challenges. If exposed to heat with chemicals, it can be blued or blackened. The surface can be polished, distressed, oiled, stained, and enhanced in ways many other metals only try to duplicate. Steel can be treated with wax or oils or they can be coated to maintain the surface finish and resist corrosion. When steel is first manufactured, its mill-finish has a blue-gray appearance. Steels, if exposed to moisture in liquid or gaseous state, will develop the characteristic red rust. However, steel can be a very intriguing surfacing material under the right conditions - and with the right alloys. Steel is usually considered a utilitarian material, better used as a skeleton, hidden from view by the beauty of another material. We selectively partner with vendors offering the highest quality materials available in many sizes and thicknesses. *Although we do not offer supply only sheets of steel, we are happy to custom fabricate based upon your project’s needs. ![]()
