Rimless frontlit channel letters are a type of illuminated 3D signage used for commercial branding, typically mounted on building exteriors or storefronts. Unlike traditional channel letters with a metal trim securing the face, rimless letters have a cleaner, more modern appearance, thanks to an acrylic face that is flush-mounted directly to the letter body without a metal border.
Construction Details:
1. Letter Face
1) Material: High-impact acrylic (usually 3mm–5mm thick)
2) Color: Customizable to brand colors; can be translucent for LED diffusion
3) Finish: Can be matte, gloss, or even custom printed
4) Mounting Style: Glued or laser-bonded directly to the returns (sides), with no rim around the edges
2. Letter Returns (Sides)
1) Material: Aluminum or stainless steel (standard), often 1"–5" deep
2) Color: Powder-coated or painted to match brand colors or face
3) Role: Encloses the sides of the letter and holds the face in place
3. Back (Letter Can)
1) Material: Aluminum or composite metal panel

3) Mounting: Flush mount to wall or raceway mount (optional for ease of installation)
4. Lighting (Illumination)
