Anodized Cast Aluminum Sign Letters

Anodized cast aluminum sign letters suit the grandeur and longevity of landmark structures such as schools, universities, government buildings, museums, theaters, and monuments. These letters are cast from molten aluminum, and anodized for long-lasting durability against the elements.  

The thickness of the letters varies based on your selected font and letter height.  See the product image for your selected font for figures.

Anodization is an electrochemical process that creates a protective, thicker layer of aluminum oxide on the surface of aluminum. This process makes the aluminum surface harder, more durable, and resistant to corrosion. It also makes the surface porous, which allows us to color this oxide layer.

Anodized aluminum sign letters are a popular choice for outdoor applications for three main reasons:

1. Enhanced Durability and Protection: The anodized layer is significantly harder than raw aluminum, providing exceptional resistance to scratches, abrasion, and general wear and tear. This protective layer also makes the letters highly resistant to corrosion, including from harsh environments like salt spray (important for seaside locations) and chemicals.

2. Longer Lifespan: Due to the increased hardness and corrosion resistance, anodized aluminum sign letters generally last much longer than unanodized or painted aluminum.

3. Aesthetic Appeal and Color Stability: Anodization allows for a wide range of colors to be permanently integrated into the aluminum's surface, offering a consistent and appealing finish that won't chip, peel, or fade from UV exposure as easily as painted surfaces. The process also preserves the metal's natural metallic luster.
