However, the material is not suitable for direct fix installation and rail and bracket systems can be costly.Ĭorten steel is also sensitive to humid subtropical climates, and in such environments, it is possible that its natural protective patina may not stabilize but instead continue to corrode.īy using our PPC Corten cladding effect on aluminium panels we can create a facade with increased strength and stability whilst resembling the desired striking visual effect. The features of robustness and improved resistance to corrosion make Corten such a popular choice specification. Our polyester powder coating range includes a wide selection of interesting colours and textures as well as our corten cladding effect, including plain oxide, tile, soft, natural stone and crystal patina. The deep copper and dark brown tones of the powder coated finish layered over a textured surface creates an almost identical resemblance to natural corten. The PPC finish can be applied to our Unity rainscreen cladding panels and fire test rated Ultima aluminium insulated panels. We can replicate the natural oxidised appearance of corten steel using our polyester powder coating process. As a result, Corten steel is commonly used in outdoor applications or environments where normal steel would be inclined to rust. It is this combination that creates its unique rusting properties as well as its distinctive appearance. Unit 25 Cambridge Science Park – CambridgeĬorten Steel is created by combining a mixture of steels and alloys.3 Glass Wharf, Temple Quarter – Bristol.Ultima A1 & A2 Fire Rated Insulated Spandrel Panels.Consulting with experts in materials and design can ensure you make the right selection for your specific application. The choice between the two grades should be based on factors such as project requirements, availability, and design preferences. In summary, both Corten A and Corten B are excellent choices for projects requiring weathering steel properties and a distinctive appearance. Consulting with a materials expert or engineer can help determine which grade is most suitable for your application. Project Requirements: Consider the specific requirements of your project, including structural needs and environmental conditions. In some regions, one grade may be more readily available than the other. The choice between the two may come down to the specific hue and texture desired for the project.Īvailability: Availability may vary depending on your location and supplier. The formation of the protective rust layer is a key feature of both grades.Īesthetic Appeal: Both grades develop the characteristic rust patina, giving them their signature appearance. The choice between Corten A and Corten B may depend on factors such as availability, project requirements, and design preferences.Ĭorrosion Resistance: Both Corten A and Corten B offer excellent corrosion resistance when exposed to outdoor conditions. It forms a protective rust layer when exposed to the elements, which provides corrosion resistance and a unique appearance.Īpplications: Corten B is used in similar applications as Corten A, particularly in structural and architectural projects. Weathering Properties: Corten B shares the same weathering characteristics as Corten A. However, Corten B has a higher phosphorus content. It contains small amounts of copper, chromium, nickel, and phosphorus, similar to Corten A. Its aesthetic appeal, combined with its corrosion resistance, makes it a popular choice for outdoor and exposed environments.Ĭhemical Composition: Corten B has a slightly different chemical composition compared to Corten A. This patina acts as a barrier against atmospheric corrosion and can extend the material’s lifespan.Īpplications: Corten A is commonly used in architectural applications, outdoor sculptures, cladding, and structural components. ![]() When exposed to the elements, it develops a protective layer of rust on the surface, which not only prevents further corrosion but also gives the steel its distinctive reddish-brown appearance. Weathering Properties: Corten A is known for its excellent weathering properties. The presence of these alloying elements enhances the steel’s resistance to atmospheric corrosion. Selecting the right grade of Corten steel is crucial when working with this material, as it can impact the final appearance and performance of your project.Ĭhemical Composition: Corten A is primarily composed of iron, with small amounts of copper, chromium, nickel, and phosphorus. Understanding Corten Steel Grades – Corten A vs. ![]() Below, we’ll explore the differences between these two grades: ![]() The two most recognized grades used for Corten are Corten A and Corten B. Corten steel is often associated with its weathering steel properties, but there are different grades within the Corten family.
