Channel Letters
Visible by day, luminous at night — channel letters give a sign great depth and precision.
- Material
- Acrylic or PC face, metal returns
- Illumination
- Face-lit, 12V/24V LED
- Mounting
- Direct-to-facia or raceway
- Max letter size
- 1–2m standard, larger by arrangement
Each letter is generally lit from the inside, with light shining through the plastic sign face — or out the back of the letter, known as halo-lit or reverse channel letters. As with most of the signs we manufacture, channel letters are custom fabricated from metal and plastic.
Channel letters may be installed directly to the building facia, with each letter mounted individually, or on a raceway — a pre-fabricated metal box that runs the length of the sign and is mounted to the facia. Your installation type may be determined by city ordinance or the building owner's sign criteria.

Larger letters run deeper so the light source sits far enough back to spread evenly. Smaller letters use LED strip, larger ones use modules, and a letter-shaped board gives the most even result for premium and chain work.
Letters fix to concrete shear walls, load-bearing beams or columns. Never to hollow brick, aerated block, insulation layers or render alone — these fail over time and present a serious safety risk. Old or cavity walls are reinforced first with pre-embedded steel plate or box-section framing.
Large letters need an internal keel frame fixed back to the structure. High-rise letters mount to a support backing frame and require structural drawings, wind-load calculations and electrical schematics.

Face & lighting combinations
The face color and the light color are separate choices. A white face reads neutral by day and takes whichever light color you specify; a colored face keeps its color lit and unlit.

05Questions2 items
Can channel letters be made to match our exact brand fonts and shapes?
In principle, yes — we check stroke width, scale, and the finished effect against what the chosen material, fabrication method, and installation environment can safely support. If an exact match isn't feasible as designed, we'll work through practical alternatives, like widening a stroke that's too thin to illuminate or splicing an oversized letter, while staying as close to the original design as possible. Safety always takes priority.
What wall-mounting and electrical requirements should we plan for?
Letters should anchor to concrete shear walls, structural beams, or columns — never to hollow brick, aerated block, insulation, or a coating layer alone, which fails over time. Large letters need an internal support frame, and letters on tall buildings require a backing structure plus supporting documentation (structural drawings, wind-load calculations, electrical schematics). Power runs on low-voltage 12V or 24V through a weatherproof supply with ground-fault protection, sized at 1.3× the actual load, and routed through PVC or metal conduit rather than exposed wire.
