CHANNEL LETTER SIGNS Channel letters are custom-made metal or plastic letters that are commonly used on the buildings of businesses, churches, entertainment venues, and other organizations for exterior signage.
A standard channel letter is a 3 dimensional graphic sign element. Its channel is fabricated from sheet metal, most often aluminum since it will not rust.
The channel letter can is painted and fitted with any lighting components necessary such as neon gas tubes or light-emitting diode (LED) modules.
Exposed neon channel letter signs resemble standard letters, but the neon is covered with a clear acrylic face to keep birds from making a nest in a channel letter.
