The channel letters we manufacture are made of aluminum and cut by a CNC router. The router creates the back of the channel and is the basis for the letter shape. Returns, the sides of the letter, are then formed by bending a 3- to 6-inch-wide strip of aluminum sheet around the aluminum back. This return can be welded or bent depending on what type of letter is chosen. The shape made from bending is called the “can”. If welded, the letter can is then painted and fitted with LED modules. If preformed, the letter can isn’t painted because it comes pre-colored. Acrylic or polycarbonate is then cut to fit the face of the can and then trimmed on the edges. Trimming gives a finished appearance and fastens the face to the letter can.
