Signage Lighting Profiles

Acrylic profiles for light boxes, channel letters and edge-lit signs – UV-stable sections that hold clarity through years of exposure.

What this application demands from the profile

Signage is the one application where UV stability is non-negotiable. A sign face that yellows or hazes is a visible failure, and it fails in public. That is why acrylic is the material for signage rather than standard polycarbonate.

The second requirement is uniformity: an illuminated face has to read evenly, which makes diffusion and light-guide geometry the design problem rather than the shape of the section.

Profile requirements

  • UV-stable acrylic that keeps clarity over years of exposure
  • Diffusion tuned for even illumination across the face
  • Light-guide sections for edge-lit applications
  • Tinted and opal options for brand colours
  • Trim and frame geometry extruded into the section
  • Protective film so faces arrive unmarked

Frequently Asked Questions

UV stability. PMMA resists yellowing far better than standard PC, which matters when the face is exposed to daylight for years.
Yes. Light-guide profiles are extruded in acrylic with diffusion tuned for even illumination from the edge.
Yes. Tinted and opal options are available and colour can be matched to RAL or Pantone.
