What Is a Channel Letter Sign on the Outside?
Exterior channel letter signs are three-dimensional signs made for building facades and branding on the outside of buildings. This product is made up of individual letters that are attached directly to the outside of a building to show off business names, logos, or brand identities.
Businesses, wedding venues, hotels, retail brands, and corporate buildings all use channel letter signs a lot because they are easy to see and look professional.
Building and Materials
Exterior channel letter signs are made with strong materials that can withstand the weather.
Some common parts of a building are:
Letter bodies made of aluminum or metal
Choices for acrylic or metal faces
Finishes that are painted or coated
LED lights inside (optional, depending on design)
Each letter is made by hand to make sure the proportions are exact and the visual quality is always the same.
Different Ways to Light
Depending on what the project needs, channel letters can be made with or without lights.
There may be different ways to set up the lights, such as:
LED channel letters with lights in the front
Channel letters with backlighting (halo lighting)
Solid letters that don’t light up
Lighting makes things easier to see at night while keeping things clean during the day.
