Etched Aluminum
Aluminum combines durability, lightweight construction, and corrosion resistance. Here’s the guide and resources to specify DMD etched aluminum for your project.
For architectural systems, aluminum offers numerous advantages, especially for structural systems. Its low density makes it easy to handle during construction, reducing labor and transportation costs, and it naturally forms a protective oxide layer that prevents corrosion and extends the lifespan of exterior components.
Most architectural aluminum is painted or anodized into uniformity. Dissimilar takes a different approach, providing etched and patinated surfaces that give aluminum the depth and character of a natural metal. We can keep its corrosion resistance and lightweight properties, and combine it with unique aeshtetics.
Dissimilar patina engineers work with your project to develop an aluminum surface that complements your desired visual end product.
