Cast aluminum letters are formed using precision molds to create flat or prismatic letter profiles with added depth and smooth, crisp edges. This added dimension delivers a more substantial presence and is a cost-effective alternative to flat-cut metal, especially for standard fonts and sizes. Commonly used for building signage, educational institutions, and municipal facilities, cast aluminum letters balance durability with classic appeal.

Available in natural satin with a horizontal grain, painted in your choice of color, or finished with a durable anodized coating. Each order includes stud mounting hardware and an installation template, with optional rail mounting available. Order online for standard options, or request a quote for custom fonts, unique layouts, or larger projects. Rush production and nationwide installation are available.

Frequently Asked Questions

What are cast aluminum letters used for?

Cast aluminum letters are ideal for building signage, institutional entrances, public spaces, and wayfinding where a clean, dimensional look is desired. The casting process adds depth and permanence for both indoor and exterior applications.

What finishes are available for cast aluminum letters?

We offer brushed, polished, painted, and anodized finishes. Brushed satin is the most popular, but painted finishes allow for vibrant or brand-specific colors. Clear anodized options add durability, especially in outdoor or coastal environments.

What sizes and depths (thicknesses) are available?

Cast aluminum letters are available in standard sizes from 2″ to 24″ tall, with depths typically ranging from ⅜″ to 1½″ depending on letter height and font. Larger letters are cast with more depth for a balanced appearance.

How are cast aluminum letters installed?

Most cast aluminum letters are stud-mounted for secure attachment to surfaces like concrete, brick, or wood. Spacers can be added for a dimensional effect. We include a mounting template and hardware with every order, and installation is available nationwide.

What’s the difference between cast and cut aluminum letters?

Cast aluminum letters are made in molds, resulting in thicker, dimensional letters with deeper profiles. Cut aluminum letters are waterjet-cut from flat sheets, offering a thinner, modern look with sharp edges. Cast is better for prismatic and traditional fonts.

What is a prismatic face on a cast aluminum letter?

A prismatic face features beveled slopes that angle toward the center of the letter, creating depth and visual interest. This classic style is available in standard fonts like Trajan and is often used on cast letters for a bold, architectural effect.

Can you make cast aluminum letters in a custom font?

Yes. We can create custom letterforms or logos in cast aluminum, including prismatic faces. Custom casting requires a unique mold, which increases cost and lead time, but results in a one-of-a-kind design.

Are cast aluminum letters weatherproof?

Yes. Cast aluminum is corrosion-resistant and well suited for long-term exterior use. We recommend a painted or anodized finish to protect against oxidation, especially in wet or coastal climates.

How does the design and proofing process work?

After receiving your deposit, we’ll send a detailed digital layout showing font, size, spacing, and mounting. You can request up to two revisions. Once approved, we begin production and ship your letters with all hardware and instructions.

What size letters should I get to fit my building?

Our online builder gives an approximate length based on your phrase and letter height. In the proofing phase, we’ll show the exact dimensions and can mock up your lettering on a photo of your building for scale reference.
