Channel Letter Sign

They’re a great choice for a bold impression.

Why go with a Channel Letter sign? They’re very popular with our customers these days, and for good reason. They’re beautiful to look at, are highly visible both day and night, are energy efficient, and allow for some wonderfully creative 3D designs. They are found on building exteriors, as well as inside many high end malls. The bottom line is that Channel Letter signs are an excellent choice for many businesses.


Here are a few details about Channel Letter signs, so you can be more informed when you talk to our sign team.

A Channel Letter sign is made of individually constructed 3D letters and shapes. The letters are crafted by BSC Signs metal fabricators in our Metro Denver facility.  Aluminum is the preferred material for Channel Letter signs as it will not rust. The letters vary in depth from 2” to 6” inches or more, depending on the overall size of the sign. The face of each letter is capped with a translucent plastic material.

This type of sign uses high-efficiency LED lighting. The LEDs are mounted inside each letter and provide bright, even illumination. For daytime viewing, the channel letters are highly visible, while at night they really stand out.

Once the letters and shapes are ready, they are usually first mounted on a panel, although it’s possible to mount individual channel letters directly on an exterior wall. The designer may add other elements and accents to complete the overall look of the sign.

The faces of the letters can include various colors, with white being a popular choice. The letters can also have additional design elements, as you can see in the City Smiles sign we installed in Denver. Our sign designers can create custom shapes using the same techniques used to form the letters. The building shape in the City Smiles sign is a good example.

The Reverse Channel sign adds a beautiful, dramatic twist to this sign theme. Instead of directly illuminating the front of each letter, the light is directed towards the back, which is left open. Light spills onto the back panel or wall, creating a beautiful halo of light that surrounds each letter.

The letters in Reverse Channel signs are capped with aluminum and often painted black, so that all of the light is directed to the back. The dark letters create the contrast needed to achieve the glow effect.

If you live in Metro Denver, you can see the Reverse Channel sign we created for Unser Racing. It’s located along U.S. Hwy 36 near the I-25 interchange, close to downtown. You can’t miss it, as it’s visible from a long way off at night!
