Standard channel letters are typically made from aluminum. A computer-controlled router table cuts a flat aluminum sheet to create the back of the letter and form its shape. The “returns” of the letter are made by bending and forming a strip of aluminum sheet, which is three to six inches in width, around the aluminum back. This return is then welded or riveted to the back to create a solid “can” in the shape of a letter or graphic. Once the letter has been fabricated, it is painted and fitted with LED modules. To finish the letter can, a 1/8″ thick acrylic sheet is cut to create a plastic face. A trim cap is then applied to the edges of the acrylic face to give it a nice border. At night, the acrylic is front illuminated by LEDs to give a pleasant lighted letter.
