Dimensional Sign Letters — Custom 3D Lettering

Yes. Dimensional letters are fabricated from durable materials specifically suited for outdoor exposure. Metal options such as aluminum and stainless steel are corrosion-resistant, while high-impact acrylic letters are UV-stable and weather-resistant. All outdoor installations are designed to maintain a professional appearance over time with minimal maintenance.

Dimensional letters are typically mounted using a hidden stud system. Threaded studs are attached to the back of each letter and inserted into pre-drilled holes in the wall or substrate. This creates a clean, seamless appearance with no visible hardware, giving your signage a polished, professional look for both interior and exterior installations.

Dimensional letters can be produced in almost any font, size, and height. Whether you need letters that match an existing brand standard, a custom typeface, or a specific architectural aesthetic, Seiz Sign Company can fabricate letters to your exact specifications. A wide variety of thicknesses and finishes are also available to complement your design.

Dimensional letters are solid, non-illuminated 3D letters mounted directly to a wall or substrate, creating a raised, three-dimensional profile. Channel letters, by contrast, are hollow fabricated metal letters that house internal LED or neon illumination, making them visible at night. Both options provide a professional appearance, but channel letters offer added visibility for businesses in high-traffic areas.

In most jurisdictions, exterior signage — including dimensional letters — requires a sign permit to comply with local sign codes and ordinances. Seiz Sign Company provides sign code and permit assistance as part of its full-service offering, helping clients navigate local regulations efficiently so installations proceed without delays or compliance issues.

Dimensional sign letters are used across a broad range of industries including retail and storefront businesses, restaurants, hotels, healthcare facilities, universities, government buildings, and sports stadiums. They are also popular for architectural plaques, building directories, wayfinding systems, and monument signs where a professional, lasting impression is essential.
