Channel Letter

A standard channel letter is a 3 dimensional sign. Its channel is fabricated from sheet metal, most often aluminum, stainless steel, Brass or Titanium. A flat sheet of metal is typically cut by a computer controlled Laser Machine, Waterjet or CNC Router. This creates the shape of the letter. The sides of the channel letter, called the returns, are then formed by bending a 1 to 6-inch wide strip of metal sheet around the back. This return can be welded at the seam or flanged and riveted to the back to create a solid pan in the shape of the letter. The letter gets painted or various finish and fitted with any lighting components necessary such as LED modules. A translucent plastic face usually fit in the open face of the letter. When illuminated, channel letters draw the eye by frontlit, Backlit or a halo effect.
