Outdoor channel letters face weather every day, so material and sealing decide how long they look good. The build is straightforward when you specify the right front, backing and mount for exposure. Here is the spec guide.
Materials and protection
| Element | Recommendation |
|---|---|
| Face | Acrylic or polycarbonate, UV-stable |
| Body | Aluminium, corrosion-resistant |
| Sealing | Gasketed, moisture-resistant |
| Mount | Standoffs or raceway, secured |
Exposure notes
Match the face material to sun exposure (UV-stable acrylic resists yellowing) and secure the mount against wind. Low-voltage LED keeps the install safe.
Maintenance
LED letters need little service; occasional cleaning and a check of the driver enclosure keep them lit for years.
