- What are channel letters?
- Channel letter are dimensional signs that are made of metal, usually aluminum, and are generally lit to be seen at night. A flat sheet of aluminum is typically cut on a table by a computer-controlled router, creating the back of the letter and defining it's shape. The sides of the channel letter, called the returns, are then formed by bending a 3 to 6-inch-wide strip of aluminum sheet around the aluminum back. This return can be welded at the seam or flanged and riveted to the back to create a solid can, with sides and a bottom, in the shape of the letter. The letter can is painted and fitted with any lighting components necessary such as neon gas tubes or light-emitting diode (LED) modules. A translucent plastic face usually of 3/16" thick sheet acrylic fiber or polycarbonate is cut to fit the open face of the letter can. A trim cap border is applied to its edges which gives the letter face a finished appearance and creates a fastening surface to attach it to the letter can. When illuminated at night, channel letters draw the eye of passers-by. Source
- Channel letters are a good choice for building signs since they stand out on buildings, and can be illuminated to draw even more attention. Channel Letters withstand the weather well and are build to survive for years outside. At Impact Signs we've been building channel letters for over 30 years. Our letters are made of aluminum, with the backs and returns being welded together. We use quality plexiglass for the letter faces and can implement either LED or neon. Some letters have specially colored faces, which is acheived by using translucent colored, or printed vinyls. Our channel letter fabrication methods, including all wiring and electrical components meet UL standards. We can meet any code requirements set forth by local government or landlords.
