Polished & Dark Bronze Coated Aluminum Sign Letters & Numbers

Polished and dark bronze coated aluminum sign letters are treated for greater durability, and resistance to scratches and corrosion. This is done through a process called anodization, which also allows us to tint letters into different colors (e.g., gold, bronze, black). 

The letters heights range from 2 inches to 96 inches tall, and from 1/8 to 1 inch thick.

Polished and dark bronze coated aluminum sign letters and numbers are easy to install with multiple mounting options and helpful installation guides that ensure hassle-free alignment for a perfect final look.

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.
