Rust Finishes
Weathered steel and rusted steel are often desired for their warm, rich tones and surface textures, and architectural rust is no exception. Rust finishes add warmth, interest, and range to your project’s design, making them a popular choice for façades, cladding, and other architectural elements. To defy the oxidation process, we have developed a variety of corrosion-resistant rust finishes tailored for weathering steel architecture applications.
Created for weathering steel architecture, our finishes reproduce the rich patina and depth of aged steel on durable architectural aluminum. The result gives architects the appearance of authentic rusted steel with greater consistency, lighter weight, and significantly reduced maintenance.
Below is a sampling of our rust finishes, but we can also create custom, one-of-a-kind designs specific to your needs. If you don’t see exactly what you’re looking for, select the closest option and let us know how you would like to see it adjusted. We’ll work with you to create a unique material for your project.

How do I specify a Rust finish in my project documents?
We can provide finish names, color codes, product facts, and specification support so you can accurately reference the rust finish in your drawings and specifications. Visit our Specification Builder to walk you through our standard product offerings and show you the optimal sizes, options available and generate a copy-and-pasteable version sent directly to your email.
What are rusted steel and weathering steel finishes?
Traditional rusted steel develops when steel is exposed to the elements and oxidation creates a natural patina across the surface. Weathering steel was developed to use this oxidation as part of the material’s appearance and protective surface, making it a popular material in weathering steel architecture.
However, naturally weathered steel can continue to corrode in certain environments and may create staining or maintenance concerns. Pure + FreeForm recreates the appearance of rusted and weathered steel using high-performance finishes applied to architectural aluminum. Our rusted steel finishes provide the depth, color variation, matte texture, and character associated with naturally aged metal without relying on active corrosion.
These rust finishes can be used as weathered steel cladding, for millwork and any of our other product applications. To see examples of projects keep scrolling, or check out our systems to see what is the right fit for your project needs.
Frequently Asked Questions
Unlike traditional weathering steel that forms a protective rust layer through oxidation, Pure + FreeForm rust finishes are applied as high-performance coatings on aluminum substrates. They offer the desired patina aesthetic with lighter weight, improved durability, and no risk of continued corrosion.
The rust finish family includes a range of tones and textures — from earthy rust patinas like Serra and Mature Rust to more dynamic blends like Blue Rust and Parisian Rust, each with its own visual character and depth.
Yes. If you don’t find exactly the look you need in the standard collection, Pure + FreeForm offers custom finish development to tailor patina appearance to your project’s design intent.
Rusted steel is a broad term for steel that has developed an oxidized surface, while weathering steel is specifically designed to form a controlled protective patina when exposed to the environment. Both are valued for their warm, aged appearance in architecture. Pure + FreeForm recreates this aesthetic on architectural aluminum without relying on continued oxidation.
Using rusted steel in architecture provides the visual warmth and character of aged metal while offering long-term durability, color consistency, and reduced maintenance compared to traditional rusted materials.
