Aluminium ceiling shadow-gap profile. C-2 White colour
Aluminium Ceiling Shadow Gap Profile C-2 (RAL 9003)
Indirect LED lighting and a crisp 25 mm perimeter shadow gap for modern minimalist interiors.
The C-2 RAL 9003 profile by ASP Profiles is designed to create a clean architectural shadow gap at the wall-to-ceiling junction. Its fixed geometry ensures a consistent 25 mm reveal around the perimeter, delivering a “floating ceiling” effect and crisp modern lines.
Made from 6063-T5 aluminium alloy, the profile offers high rigidity and a precise fit. The durable RAL 9003 powder coating provides a clean white finish; other RAL colours are available on request.
The profile is ideal for concealed LED lighting with reflected (indirect) light. Its geometry gently directs light onto the wall, creating a smooth, glare-free gradient. The profile is mechanically fixed, then finished with joint compound for a seamless, flush integration.
